THE COMPANY

Comfort Systems was founded in 1996 to become a leading national provider
of comprehensive HVAC installation services and maintenance, repair and
replacement of HVAC systems, focusing primarily on the commercial and industrial
markets. On July 2, 1997, the Company acquired in separate, concurrent
transactions twelve companies and since the IPO the Company has acquired
additional companies, all of which are engaged principally in the HVAC business.
See "Recent Developments." The Company's commercial and industrial applications
include office buildings, retail centers, apartment complexes, hotels,
manufacturing plants and government facilities. The Company also provides
specialized HVAC applications such as process cooling, control systems,
electronic monitoring and process piping. Approximately 90% of the Company's pro
forma combined 1996 revenues of $167.5 million was derived from commercial and
industrial customers, with approximately 53% of combined revenues attributable
to installation services and 47% attributable to maintenance, repair and
replacement services. Since the IPO, and through October 13, 1997, the Company
has acquired eleven additional mechanical contracting companies engaged
principally in the HVAC business.

The Company's commercial and industrial installation business targets
"design and build" projects where the Company is responsible for designing,
engineering and installing a cost-effective, energy-efficient system, customized
to meet the specific needs of the building owner. Management believes that the
"design and build" segment represents a faster growing and more profitable
segment of the HVAC business than traditional "plan and spec" installation,
which is generally awarded based on a bid process.

The Company also provides maintenance, repair and replacement of HVAC
systems. Growth in this segment is driven by a number of factors, particularly
(i) the aging of the installed base, (ii) the increasing energy efficiency,
sophistication and complexity of HVAC systems and (iii) the increasing
restrictions on

the use of refrigerants commonly used in older HVAC systems. The energy
efficiency and sophistication of new HVAC systems are encouraging building
owners to upgrade and reconfigure their current HVAC systems. Moreover, the
increasing sophistication and complexity of these HVAC systems are leading many
commercial and industrial building owners and property managers to outsource
maintenance and repair through service agreements with HVAC service providers.
Service agreements lead to better utilization of personnel, link the customer
with the Company should a major repair or replacement be needed and result in
recurring revenues. The Company believes there is also an opportunity to expand
its presence in the highly-fragmented residential maintenance, repair and
replacement market. The replacement segment of the residential HVAC market has
grown significantly in recent years as a result of the aging of the installed
base of residential HVAC systems, the introduction of more energy-efficient
systems and the upgrading of older homes with central air conditioning.

The Company plans to achieve its goal of becoming a leading national
provider of comprehensive HVAC services by improving operations, emphasizing
continued internal growth and expanding through acquisitions.

OPERATING STRATEGY. The Company believes there are significant
opportunities to increase its profitability and that of subsequently acquired
businesses. The key elements of the Company's operating strategy are:

FOCUS ON COMMERCIAL AND INDUSTRIAL MARKETS. The Company believes that
the commercial and industrial HVAC markets are attractive because of their
growth opportunities, diverse customer base, attractive margins and
potential for long-term relationships with building owners and managers,
general contractors and architects.

OPERATE ON DECENTRALIZED BASIS. The Company believes that, while
maintaining strong operating and financial controls, a decentralized
operating structure will retain the entrepreneurial spirit present in each
of the Founding Companies and will allow the Company to capitalize on the
considerable local and regional market knowledge and customer relationships
possessed by each Founding Company.

ACHIEVE OPERATING EFFICIENCIES. The Company intends to use its
increased purchasing power to gain volume discounts in areas such as HVAC
components, raw materials, service vehicles, advertising, bonding and
insurance. In addition, the Company will identify "best practices" that
can be successfully implemented throughout its operations.

ATTRACT AND RETAIN QUALITY EMPLOYEES. The Company intends to attract
and retain quality employees by providing them (i) an enhanced career path
from working for a larger public company, (ii) additional training,
education and apprenticeships to allow talented employees to advance to
higher-paying positions, (iii) the opportunity to realize a more stable
income and (iv) improved benefits packages.

INTERNAL GROWTH. A key component of the Company's strategy is to continue
the internal growth at the Founding Companies and subsequently acquired
businesses. The key elements of the Company's internal growth strategy are:

CAPITALIZE ON SPECIALIZED TECHNICAL AND MARKETING STRENGTHS. The
Company believes it will be able to expand the services it offers in its
local markets by leveraging the specialized technical and marketing
strengths of individual Founding Companies.

ESTABLISH NATIONAL MARKET COVERAGE. The Company believes that
significant demand exists from large national companies to utilize the
services of a single HVAC service provider and believes existing local and
regional relationships can be expanded as it develops a nationwide network.

4
<PAGE>
ACQUISITIONS. The Company believes that, due to the highly fragmented
nature of the HVAC industry, it has a significant opportunity to achieve its
acquisition strategy. The key elements of the Company's acquisition strategy
are:

ENTER NEW GEOGRAPHIC MARKETS. The Company will pursue acquisitions
that are located in new geographic markets, are financially stable, and
which will have the customer base, technical skills and infrastructure
necessary to be a core business into which other HVAC service operations
can be consolidated.

EXPAND WITHIN EXISTING MARKETS. Once the Company has entered a
market, it will seek to acquire other well-established HVAC businesses
operating within that region and will also pursue "tuck-in" acquisitions
of smaller companies, whose operations can be integrated into an existing
operation to leverage the Company's infrastructure.

ACQUIRE COMPLEMENTARY BUSINESSES. The Company will focus on the HVAC
industry and may also acquire companies providing complementary services to
the same customer base, such as commercial and industrial process piping
and plumbing and electrical companies.

RECENT DEVELOPMENTS

During late 1996 and early 1997, members of the Company's management team
and certain consultants were assembled to pursue the consolidation of the
Founding Companies. Notre, a consolidator of highly-fragmented industries,
provided the Company with expertise regarding the consolidation process and
advanced the Company the funds needed to pay organizational and Offering
expenses. In connection therewith, during 1996 and January and February 1997,
Comfort Systems sold an aggregate of 1,269,935 shares of Common Stock to
management of and consultants to the Company at a price of $0.01 per share. As a
result, the Company recorded a non-recurring, non-cash compensation charge of
$11.6 million (the "Compensation Charge") in the first quarter of 1997,
representing the difference between the amount paid for the shares and the
estimated fair value of the shares on the date of sale. This Compensation Charge
of $11.6 million is not included in pro forma combined net income.

On July 2, 1997, the Company consummated the IPO and the Mergers. In
connection therewith, the Company issued 7,015,000 shares of Common Stock at a
price of $13.00 per share (less underwriting discounts and commissions).

The aggregate consideration paid by Comfort Systems in the Mergers
consisted of $45.3 million in cash and 9,720,927 shares of Common Stock, plus
the assumption of $20.4 million of existing debt of the Founding Companies. The
consideration paid by Comfort Systems for each Founding Company was negotiated
by the parties and was based primarily upon the pro forma adjusted net income of
each Founding Company. For a more detailed description of these transactions,
see "Certain Transactions -- Organization of the Company."

Between January 1, 1997 and the date of the Mergers, each Founding Company
which was a C Corporation, except Atlas, distributed to its stockholders an
amount equal to its net income for the period from January 1, 1997 through the
date of the Mergers (the "Interim Earnings Distributions"). These aggregate
distributions were $1.5 million and were funded from the Founding Companies'
cash and from borrowings from existing sources available to the Founding
Companies.

Since the IPO, and through October 31, 1997, the Company has acquired
sixteen additional mechanical contracting companies engaged principally in the
HVAC business. The Company paid approximately $7.7 million in cash, issued
2,516,286 shares of Common Stock and issued $3.1 million in convertible
subordinated notes as consideration for these companies. The Company will
account for seven of these acquisitions as pooling-of-interests transactions and
the remaining four acquisitions will be accounted for as purchase transactions.
Annualized revenues were approximately $100 million for these acquisitions.

Comfort Systems USA, Inc. was incorporated in 1996 in Delaware. The
Company's executive offices are located at Three Riverway, Suite 200, Houston,
Texas 77056, and its telephone number is (800) 723-8431.

RISK FACTORS

AN INVESTMENT IN THE SHARES OF COMMON STOCK OFFERED BY THIS PROSPECTUS
INVOLVES A HIGH DEGREE OF RISK. IN ADDITION TO THE OTHER INFORMATION IN THIS
PROSPECTUS, THE FOLLOWING RISK FACTORS SHOULD BE CONSIDERED CAREFULLY IN
EVALUATING AN INVESTMENT IN THE COMMON STOCK. THIS PROSPECTUS CONTAINS CERTAIN
FORWARD-LOOKING STATEMENTS. ACTUAL RESULTS COULD DIFFER MATERIALLY FROM THOSE
PROJECTED IN THE FORWARD-LOOKING STATEMENTS AS A RESULT OF ANY NUMBER OF
FACTORS, INCLUDING THE RISK FACTORS SET FORTH BELOW AND ELSEWHERE IN THIS
PROSPECTUS.

ABSENCE OF COMBINED OPERATING HISTORY. Comfort Systems was founded in 1996
but conducted no operations and generated no revenues prior to the Mergers on
July 2, 1997. The Founding Companies operated as separate independent entities
prior to the IPO, and there can be no assurance that the Company will be able to
integrate the operations of these businesses successfully or to institute the
necessary systems and procedures, including accounting and financial reporting
systems, to manage the combined enterprise on a profitable basis. The Company's
management group has been assembled only recently, and there can be no assurance
that the management group will be able to effectively manage the combined entity
or successfully implement the Company's operating strategy, internal growth
strategy and acquisition program. The pro forma combined historical financial
results of the Founding Companies primarily cover periods when the Founding
Companies and Comfort Systems were not under common control or management and,
therefore, may not be indicative of the Company's future financial or operating
results. The inability of the Company to integrate the Founding Companies
successfully would have a material adverse effect on the Company's business,
financial condition and results of operations and would make it unlikely that
the Company's acquisition program will be successful. See
"Business -- Strategy" and "Management."

RISKS RELATED TO THE COMPANY'S ACQUISITION STRATEGY. The Company intends
to continue to grow significantly through the acquisition of additional HVAC and
complementary businesses. The Company expects to face competition for
acquisition candidates, which may limit the number of acquisition opportunities
and may lead to higher acquisition prices. There can be no assurance that the
Company will be able to identify, acquire or manage profitably additional
businesses or to integrate successfully any acquired businesses into the Company
without substantial costs, delays or other operational or financial problems.
Further, acquisitions involve a number of special risks, including failure of
the acquired business to achieve expected results, diversion of management's
attention, failure to retain key personnel of the acquired business and risks
associated with unanticipated events or liabilities, some or all of which could
have a material adverse effect on the Company's business, financial condition
and results of operations. Customer dissatisfaction or performance problems at a
single acquired company could have an adverse effect on the reputation of the
Company generally and render ineffective the Company's national sales and
marketing initiatives. The Company may consider acquiring complementary
businesses in the electrical, process piping and plumbing industries, and there
can be no assurance that these complementary businesses can be successfully
integrated. In addition, there can be no assurance that the Founding Companies
or other businesses acquired in the future will achieve anticipated revenues and
earnings. See "Business -- Strategy."

RISKS RELATED TO ACQUISITION FINANCING. The timing, size and success of
the Company's acquisition efforts and the associated capital commitments cannot
be readily predicted. The Company intends to continue to finance future
acquisitions by using shares of its Common Stock for all or a substantial
portion of the consideration to be paid. If the Common Stock does not maintain a
sufficient market value, or if potential acquisition candidates are otherwise
unwilling to accept Common Stock as part of the consideration for the sale of
their businesses, the Company may be required to utilize more of its cash
resources, if available, in order to initiate and maintain its acquisition
program. If the Company does not have sufficient cash resources, its growth
could be limited unless it is able to obtain additional capital through debt or
equity financings. The Company has obtained a bank line of credit of $75.0
million from Bank One, Texas, NA ("Bank One") as agent, and a group of other
banks, for working capital and acquisitions. As of October 31, 1997, borrowings
under the line of credit were $17.3 million, which was used to repay existing

9
<PAGE>
indebtedness of the Founding Companies. The line of credit is subject to
customary financial covenants and drawing conditions. See "Management's
Discussion and Analysis of Financial Condition and Results of
Operations -- Combined Liquidity and Capital Resources."

RISKS RELATED TO OPERATING AND INTERNAL GROWTH STRATEGY. Key elements of
the Company's strategy are to improve the profitability of the Founding
Companies and subsequently acquired businesses and to continue to expand the
revenues of the Founding Companies and any subsequently acquired businesses. The
Company intends to seek to improve the profitability of the Founding Companies
and any subsequently acquired businesses by various means, including increased
purchasing efficiencies and a reduction, in some cases, of duplicative operating
costs and overhead. The Company's ability to increase the revenues of the
Founding Companies and any subsequently acquired company will be affected by
various factors, including demand for new or replacement HVAC systems, the level
of new construction, the Company's ability to expand the range of services
offered to customers of individual Founding Companies and other acquired
businesses, the Company's ability to develop national accounts and other
marketing programs in order to attract new customers and the Company's ability
to attract and retain a sufficient number of qualified HVAC technicians and
other necessary personnel. Many of these factors are beyond the control of the
Company, and there can be no assurance that the Company's operating and internal
growth strategies will be successful or that it will be able to generate cash
flow adequate for its operation and to support internal growth. See
"Business -- Strategy."

COMPETITION. The HVAC industry is highly competitive and is served by
small, owner-operated private companies and several large companies. Certain of
these competitors may have lower overhead cost structures and may, therefore, be
able to provide their services at lower rates than the Company. The HVAC
industry is currently undergoing rapid consolidation on both a national and a
regional level by other companies which have acquisition objectives which are
the same as or similar to the Company's objectives. These companies and other
consolidators may have greater financial resources than the Company to finance
acquisition and internal growth opportunities and might be willing to pay higher
prices than the Company for the same acquisition opportunities. Additionally,
HVAC equipment manufacturers and certain public utilities are beginning to enter
the maintenance, repair and replacement segment of the HVAC industry. These
companies generally are better capitalized, have greater name recognition and
may be able to provide these services at a lower cost. Consequently, the Company
may encounter significant competition in its efforts to achieve both its
acquisition and internal growth objectives as well as its operating strategy to
increase the profitability of the Founding Companies and subsequently acquired
companies. See "Business -- Competition."

AVAILABILITY OF HVAC TECHNICIANS. The timely provision of high-quality
installation service and maintenance, repair and replacement of HVAC systems by
the Company requires an adequate supply of skilled HVAC technicians.
Accordingly, the Company's ability to increase its productivity and
profitability will be limited by its ability to employ, train and retain the
skilled technicians necessary to meet the Company's service requirements. From
time to time, there are shortages of qualified HVAC technicians, and there can
be no assurance that the Company will be able to maintain an adequate skilled
labor force necessary to operate efficiently, that the Company's labor expenses
will not increase as a result of a shortage in the supply of skilled technicians
or that the Company will not have to curtail its planned internal growth as a
result of labor shortages. See "Business -- Employees" and " -- Recruiting,
Training and Safety."

SEASONAL AND CYCLICAL NATURE OF THE HVAC INDUSTRY. The HVAC industry is
subject to seasonal variations. Specifically, the demand for new installations
is generally lower during the winter months due to reduced construction activity
during inclement weather and less use of air conditioning during colder months.
Demand for HVAC maintenance, repair and replacement services is generally higher
in the second and third calendar quarters due to the increased use of air
conditioning during warmer months. Accordingly, the Company expects its revenues
and operating results generally will be lower in the first and fourth quarters.
Historically, the construction industry has been highly cyclical. As a result,
the Company's volume

10
<PAGE>
of business may be adversely affected by declines in new installation projects
in various geographic regions of the United States.

REGULATION. HVAC systems are subject to various environmental statutes and
regulations, including the Clean Air Act and those regulating the production,
servicing and disposal of certain ozone depleting refrigerants used in HVAC
systems. There can be no assurance that the regulatory environment in which the
Company operates will not change significantly in the future. Various local,
state and federal laws and regulations impose licensing standards on technicians
who install and service HVAC systems. The Company's failure to comply with these
laws and regulations could subject it to substantial fines and the loss of its
licenses. See "Business -- Governmental Regulation and Environmental Matters."

RELIANCE ON KEY PERSONNEL. The Company will be highly dependent on the
continuing efforts of its executive officers and the senior management of the
Founding Companies, and the Company likely will depend on the senior management
of any significant business it acquires in the future. The business or prospects
of the Company could be affected adversely if any of these persons does not
continue in his management role until the Company is able to attract and retain
qualified replacements. See "Management."

CONTROL BY EXISTING MANAGEMENT AND STOCKHOLDERS. The Company's executive
officers and directors, former stockholders of the Founding Companies and
entities affiliated with them beneficially own approximately 58.9% of the
outstanding shares of Common Stock. These persons, if acting in concert, would
be able to exercise control over the Company's affairs, to elect the entire
Board of Directors and to control the outcome of any matter submitted to a vote
of stockholders. See "Principal Stockholders."

SUBSTANTIAL PROCEEDS OF OFFERING PAYABLE TO AFFILIATES OF FOUNDING
COMPANIES. Of the net proceeds of the IPO, $45.3 million, or approximately
53.4%, were paid as the cash portion of the purchase price for the Founding
Companies. Some of the recipients of these funds are directors of the Company or
holders of more than 5% of the Common Stock.

BENEFITS TO NOTRE AND MANAGEMENT. Notre, management and certain
consultants to the Company own in the aggregate 4,239,847 shares of Common
Stock. These stockholders acquired their Common Stock at a price of $0.01 per
share. These parties own, in the aggregate, approximately 20% of the outstanding
Common Stock. Of these shares of Common Stock, 2,742,912 shares are Restricted
Common Stock, which are entitled to elect one member of the Company's Board of
Directors and to 0.55 of one vote for each share held on all other matters on
which they are entitled to vote. Holders of Restricted Common Stock are not
entitled to vote on the election of any other directors and control in the
aggregate 8.8% of the votes of all shares of Common Stock. See "Principal
Stockholders."

NO PRIOR PUBLIC MARKET. The Company went public on July 2, 1997 and the
market price of the Common Stock may be subject to significant fluctuations in
response to numerous factors, including the timing of any acquisitions by the
Company, variations in the Company's annual or quarterly financial results or
those of its competitors, changes by financial research analysts in their
estimates of the future earnings of the Company, conditions in the economy in
general or in the Company's industry in particular, unfavorable publicity or
changes in applicable laws and regulations (or judicial or administrative
interpretations thereof) affecting the Company or the HVAC, process piping and
plumbing and electrical services industries. From time to time, the stock market
experiences significant price and volume volatility, which may affect the market
price of the Common Stock for reasons unrelated to the Company's performance.

POTENTIAL EFFECT OF SHARES ELIGIBLE FOR FUTURE SALE ON PRICE OF COMMON
STOCK. As of October 31, 1997 there were 23,492,060 shares of Common Stock
outstanding. The 7,015,000 shares sold in the IPO, 34,496 shares issued in
acquisitions and 583,878 shares registered hereunder (other than shares that may
have been or that may subsequently be purchased by affiliates of the Company)
are freely tradable. The remaining outstanding shares may be resold publicly
only following their registration under the Securities Act of 1933, as amended
(the "Securities Act"), or pursuant to an available exemption from
registration (such as provided by Rule 144 following a one year holding period
for previously unregistered shares), or upon the expiration of contractual
restrictions. Certain of the holders of these remaining shares have certain

11
<PAGE>
rights to have their shares registered in the future under the Securities Act,
but may not exercise such registration rights, and have agreed with the Company
that they will not sell, transfer or otherwise dispose of any of their shares
prior to July 2, 1998. See "Shares Eligible for Future Sale." In addition,
1,550,424 shares issued in acquisitions since the IPO will become tradeable on
the first anniversaries of such acquisitions late in the third quarter and early
in the fourth quarter of 1998, 252,292 of such shares will become tradeable
during the same period in 1999, 69,879 of such shares will become tradeable
during the same period in 2000, and 25,317 of such shares will become tradeable
during the same period in 2001. The Company also has outstanding options to
purchase up to a total of 2,258,653 shares of Common Stock. In addition, up to
7,807,374 shares issuable pursuant to a shelf registration statement for use in
connection with acquisitions may be freely traded after their issuance by
persons not affiliated with the Company unless the Company contractually
restricts their resale. The market price of the Common Stock might be adversely
affected by the sale, or availability for sale, of substantial amounts of the
Common Stock in the public market as described above.

POSSIBLE ANTI-TAKEOVER EFFECT OF CERTAIN CHARTER PROVISIONS. Comfort
Systems' Amended and Restated Certificate of Incorporation (the "Certificate of
Incorporation"), authorizes the Board of Directors to issue, without
stockholder approval, one or more series of preferred stock having such
preferences, powers and relative, participating, optional and other rights
(including preferences over the Common Stock respecting dividends and
distributions and voting rights) as the Board of Directors may determine. The
issuance of this "blank-check" preferred stock could render more difficult or
discourage an attempt to obtain control of the Company by means of a tender
offer, merger, proxy contest or otherwise. In addition, the Certificate of
Incorporation provides for a classified Board of Directors, which may also have
the effect of inhibiting or delaying a change in control of the Company. Certain
provisions of the Delaware General Corporation Law may also discourage takeover
attempts that have not been approved by the Board of Directors. See
"Description of Capital Stock."

DILUTION. Purchasers of Common Stock will experience immediate,
substantial dilution in the net tangible book value of their stock.

PRICE RANGE OF COMMON STOCK

The Company's Common Stock has traded on the New York Stock Exchange since
June 27, 1997. On October 31, 1997, the last sale price of the Common Stock was
$17 per share, as published in THE WALL STREET JOURNAL on November 3, 1997.
At October 31, 1997 there were approximately 130 stockholders of record of the
Company's Common Stock. The following table sets forth the range of high and low
sale prices for the Common Stock for the period from June 27, 1997, the date of
the IPO, through June 30, 1997, from July 1, 1997, through September 30, 1997,

Selling Stockholders of the Common Stock offered hereby. Any or all of the
shares of Common Stock may be sold from time to time (i) to or through
underwriters or dealers, (ii) directly to one or more other purchasers, (iii)
through agents on a best-efforts basis, or (iv) through a combination of any
such methods of sale.

The shares of the Common Stock offered hereby (the "Shares") may be sold
from time to time by the Selling Stockholders, or by pledgees, donees,
transferees or other successors in interest. Such sales may be made on one or
more exchanges or in the over-the-counter market, or otherwise at prices and at
terms then prevailing or at prices related to the then current market price, or
in negotiated transactions. The Shares may be sold by one or more of the
following: (a) a block trade in which the broker or dealer so engaged will
attempt to sell the Shares as agent but may position and resell a portion of the
block as principal to facilitate the transaction; (b) purchases by a broker or
dealer as principal and resale by such broker or dealer for its account pursuant
to this Prospectus; (c) an exchange distribution in accordance with the rules of
such exchange; and (d) ordinary brokerage transactions and transactions in which
the broker solicits purchasers. In effecting sales, brokers or dealers engaged
by the Selling Stockholders may arrange for other brokers or dealers to
participate. Brokers or dealers will receive commissions or discounts from
Selling Stockholders in amounts to be negotiated prior to the sale.

The Selling Stockholders and any such underwriters, dealers or agents that
participate in the distribution of the Common Stock may be deemed to be
underwriters within the meaning of the Securities Act, and any profit on the
sale of the Common Stock by them and any discounts, commissions or concessions
received by them may be deemed to be underwriting discounts and commissions
under the Securities Act. The Common Stock may be sold from time to time in one
or more transactions at a fixed offering price, which may be changed, or at
varying prices determined at the time of sale or at negotiated prices. Such
prices will be determined by the Selling Stockholders or by an agreement between
the Selling Stockholders and underwriters or dealers. Brokers or dealers acting
in connection with the sale of Common Stock contemplated by this Prospectus may
receive fees or commissions in connection therewith.

At the time a particular offer of Common Stock is made, to the extent
required, a supplement to this Prospectus will be distributed which will
identify and set forth the aggregate number of shares of Common Stock being
offered and the terms of the offering, including the name or names of any
underwriters, dealers or agents, the purchase price paid by any underwriter for
Common Stock purchased from the Selling Stockholders, any discounts, commissions
and other items constituting compensation from the Selling Stockholders and/or
the Company and any discounts, commissions or concessions allowed or reallowed
or paid to dealers, including the proposed selling price to the public. Such
supplement to this Prospectus and, if necessary, a post-effective amendment to
the Registration Statement of which this Prospectus is a part, will be filed
with the Commission to reflect the disclosure of additional information with
respect to the distribution of the Common Stock.

Under applicable rules and regulations under the Exchange Act, any person
engaged in a distribution of the Common Stock may not simultaneously engage in
market making activities with respect to the Common Stock for a period of nine
business days prior to the commencement of such distribution. In addition and
without limiting the foregoing, the Selling Stockholders and any person
participating in the distribution of the Common Stock will be subject to
applicable provisions of the Exchange Act and the rules and regulations
thereunder, including without limitation rules 10b-6 and 10b-7, which provisions
may limit the timing of purchases and sales of the Common Stock by the Selling
Stockholders or any such other person.

In order to comply with certain states' securities laws, if applicable, the
Common Stock will be sold in such jurisdictions only through registered or
licensed brokers or dealers. In certain states the Common Stock may not be sold
unless it has been registered or qualified for sale in such state, or unless an
exemption from registration or qualification is available.

DIVIDEND POLICY

The Company intends to retain all of its future earnings, if any, to
finance the expansion of its business and for general corporate purposes,
including future acquisitions, and does not anticipate paying any cash dividends

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
CONDITION AND RESULTS OF OPERATIONS

The following discussion should be read in conjunction with "Selected
Financial Data" and the Founding Companies' Financial Statements and related
Notes thereto appearing elsewhere in this Prospectus.

This discussion contains statements regarding future financial performance
and results. The realization of outcomes consistent with these forward-looking
statements is subject to numerous risks and uncertainties to the Company
including, but not limited to, the availability of attractive acquisition
opportunities, the successful integration and profitable management of acquired
businesses, improvement of operating efficiencies, the availability of working
capital and financing for future acquisitions, the Company's ability to grow
internally through expansion of services and customer bases and reduction of
overhead, seasonality and other risk factors discussed in the Registration
Statement.

INTRODUCTION

The Company's revenues are derived from providing comprehensive HVAC
installation services and maintenance, repair and replacement of HVAC systems
primarily for commercial and industrial customers. The Company's commercial and
industrial applications include office buildings, retail centers, apartment
complexes, hotels, manufacturing plants and government facilities. The Company
also provides specialized HVAC applications such as process cooling, control
systems, electronic monitoring and process piping. Approximately 90% of the
Company's pro forma combined 1996 revenues of $167.5 million was derived from
commercial and industrial customers, with approximately 53% of total revenues
attributable to installation services and 47% attributable to maintenance,
repair and replacement services.

Revenues related to commercial and industrial installation are of two
types: "design and build" and "plan and spec." Approximately 80% of the
commercial and industrial installation revenues for 1996 were generated from
"design and build" projects, which generally yield higher margins than "plan
and spec" projects because the Company is responsible for designing,
engineering and installing a cost-effective, energy-efficient system that is
customized to the specific needs of the building owner. This enables the Company
to control the customer's cost and reduce overall design and installation time.
Additionally, the costs and other terms of "design and build" projects are
normally established through relationship-based negotiation with the building
owner or its representative rather than through a competitive bid process.
"Plan and spec" installation projects typically yield lower margins than
"design and build" projects because the building's architect or consulting
engineer designs the HVAC system and the installation project is put out for
bid.

Most installation and reconfiguration projects are completed within one
year. Generally, these contracts are accounted for under the
percentage-of-completion method of accounting. Revenues are recorded based on
the percentage of costs incurred during a particular period, in proportion to
total estimated costs for each contract. Maintenance, repair and replacement
service revenues are recorded as services are performed. Costs of services
consist primarily of HVAC components, parts and materials related to new
installation, equipment maintenance and rental, salaries and benefits payable to
service and repair technicians, as well as supervisory and subcontract labor.
Selling, general and administrative expenses consist primarily of compensation
and benefits to owners as well as to sales and administrative employees, fees
for professional services, depreciation of equipment and other general office
expenses. Selling, general and administrative expenses also include incentive
and discretionary bonuses paid to owners, significant portions of which were
paid in lieu of S Corporation distributions to enable stockholders to meet their
income tax obligations.

The Founding Companies have operated throughout the periods presented as
independent, privately-owned entities, and their results of operations reflect
varying tax structures (S Corporations or C Corporations) which have influenced
the historical level of owners' compensation. Gross profit margins and selling,
general and administrative expenses as a percentage of revenues may not be
comparable among the individual Founding Companies. The owners of the Founding
Companies have agreed to certain reductions in their compensation and benefits
in connection with the organization of the Company. The Compensation

19
<PAGE>
Differential for 1996 of $6.6 million and $2.5 million for the six months ended
June 30, 1997 has been reflected as a pro forma adjustment in the Unaudited Pro
Forma Combined Statements of Operations.

The Company anticipates that following the Mergers it will realize savings
from (i) greater volume discounts from suppliers of HVAC components, parts and
raw materials; (ii) consolidation of insurance and bonding programs; (iii) other
general and administrative areas such as training and advertising; and (iv) the
Company's ability to borrow at lower interest rates than most of the Founding
Companies. It is anticipated that these savings will be offset by costs related
to the Company's new corporate management and by the costs associated with being
a public company. The Company believes that neither these savings nor the costs
associated therewith can be quantified because the Mergers have not occurred,
and there have been no combined operating results upon which to base any
assumptions. As a result, they have not been included in the pro forma financial
information included herein.

During January and February 1997, Comfort Systems sold an aggregate of
1,269,935 shares of Common Stock to management and consultants. As a result, the
Company recorded a non-recurring, non-cash Compensation Charge of $11.6 million
in the first quarter of 1997, representing the difference between the amount
paid for the shares and the estimated fair value of the shares on the date of
sale. This Compensation Charge of $11.6 million is not included in pro forma
financial information or Combined Results of Operations.

In July 1996, the Securities and Exchange Commission issued Staff
Accounting Bulletin No. 97 ("SAB 97") relating to business combinations
immediately prior to an initial public offering. SAB 97 requires that these
combinations be accounted for using the purchase method of acquisition
accounting. Under the purchase method, one of the companies must be designated
as the accounting acquirer. For the remaining companies, $139.3 million,
representing the excess of the fair value of the Merger consideration received
over the fair value of the net assets to be acquired, will be recorded as
"goodwill" on the Company's balance sheet. Goodwill will be amortized as a
non-cash charge to the income statement over a 40-year period. The pro forma
impact of this amortization expense, which is non-deductible for tax purposes,
is $3.5 million per year on an after-tax basis. Prior to the issuance of SAB 97,
goodwill and related amortization expense were not required to be recorded for
most business combinations similar to the Mergers. See "Certain
Transactions -- Organization of the Company."

COMBINED RESULTS OF OPERATIONS

The combined results of operations of the Founding Companies for the
periods presented do not represent combined results of operations presented in
accordance with generally accepted accounting principles, but are only a
summation of the revenues, cost of services and selling, general and
administrative expenses of the individual Founding Companies on a historical
basis. The combined results also exclude the effect of pro forma adjustments and
may not be comparable to, and may not be indicative of, the Company's
post-combination results of operations because (i) the Founding Companies were
not under common control or management during the periods presented; (ii) the
Founding Companies used different tax structures (S Corporations or C
Corporations) during the periods presented; (iii) the Company will incur
incremental costs related to its new corporate management and the costs of being
a public company; (iv) the Company will use the purchase method to record the
Mergers, resulting in the recording of goodwill which will be amortized over 40
years; and (v) the combined data do not reflect the Compensation Differential
and potential benefits and cost savings the Company expects to realize when
operating as a combined entity.

(2) The financial data for 1995 and 1996 both include Quality's results for the
three months ended March 31, 1996 which were as follows: revenues of $6.3
million, cost of services of $4.3 million, and selling, general and
administrative expenses of $1.6 million.

COMBINED RESULTS FOR THE SIX MONTHS ENDED JUNE 30, 1997 COMPARED TO THE SIX
MONTHS ENDED JUNE 30, 1996

REVENUES. Pro forma combined revenues increased $8.2 million, or 10.4%
million from $78.7 million for the six months ended June 30, 1996, to $86.9
million for the six months ended June 30, 1997. This resulted primarily from
increases in revenues at Tri-City, Lawrence and Quality, net of a decline at
Accurate. Revenues at Tri-City increased $5.8 million primarily due to two
design/build installation projects. One of these projects is for a large
nationally-known healthcare organization and involves the first major facility
on what is expected to be a medical campus covering more than 100 acres. The
second project is at a new fabrication facility for a major semiconductor
manufacturer. Revenues at Lawrence increased $2.2 million over the same six
month period as a result of a "design and build" installation project at a
manufacturing facility in North Carolina and a "design and build" installation
project for a nationally known consumer products company. Quality's revenues
increased $1.4 million over 1996 due to broad-based growth in its design/build
activity and its maintenance, repair and replacement service. These increases
were partially offset by a decline of $1.2 million at Accurate due to inclement
and unseasonably cool weather in Houston, its primary market, during the first
six months of 1997.

GROSS PROFIT. Combined gross profit as a percentage of revenues for the
six months of increases at Atlas, Lawrence, Quality and Eastern, net of a
decline at Tri-City. Atlas' gross margin increased as a result of its ability to
be more selective in accepting projects in design/build installation for
multi-unit facilities. Lawrence's gross margin was up as a result of its ability
to earn better margins on design/build work from a growing client base.
Quality's gross margin improved due to increasing demand for its services in its
market and because its gross margin during the first half of 1996 was somewhat
lower due to narrower margins on a large automotive industry project it
completed in the second quarter of 1996. These increases were partially offset
by a decrease in gross margin at Tri-City where the medical facility project
referred to above included a significant amount of revenue related to
subcontract work and procured equipment, both of which typically carry lower
margins. In addition, Accurate also contributed to the increase in six-month
gross margin through the use of less subcontracting.

SELLING, GENERAL AND ADMINISTRATIVE EXPENSES. Combined SG&A expenses
increased $1.1 million, or 6.7%, from $16.3 million for the six months ended
June 30, 1996, to $17.4 million for the six months ended June 30, 1997. This
increase was principally due to additions to personnel and infrastucture at
Quality, Atlas, Lawrence and Tri-City to support growth in their commercial and
industrial "design and build" installation activity. As a percentage of
revenues, SG&A decreased from 20.7% for the first half of 1996 to 20.1% for the
first half of 1997.

COMBINED RESULTS FOR 1996 COMPARED TO 1995

REVENUES. Combined revenues increased approximately $21.0 million, or
14.3%, from $146.5 million in 1995 to $167.5 million in 1996. The increase in
combined revenues occurred primarily at Atlas,

21
<PAGE>
Accurate and Lawrence. This increase in combined revenues was primarily
attributable to an increase in commercial and industrial "design and build"
revenues of approximately 15% and an increase in maintenance, repair and
replacement revenues of approximately 30%. Revenues for Atlas increased $7.6
million from 1995 to 1996 due to increasing demand by several large national
customers for HVAC "design and build" installation services provided by Atlas
for multi-unit facilities. Revenues for Accurate increased $4.6 million from
1995 to 1996 reflecting the success of an increased marketing effort along with
the addition of sales personnel and project managers. Revenues at Lawrence
increased by $4.6 million from 1995 to 1996 due to a management decision in 1995
to expand the number of general contractors for which Lawrence provides
industrial installation services and due to a large "design and build"
installation contract obtained in 1996 for a food processing facility. Seven of
the other Founding Companies reported an increase in revenues from 1995 and
1996, partially offset by a decline in revenues at Quality and Tri-City.

GROSS PROFIT. Combined gross profit increased $6.3 million, or 15.3%, from
$41.5 million in 1995 to $47.8 million in 1996, due principally to increases in
gross profit of $2.2 million at Atlas, $1.5 million at Lawrence and $1.1 million
at Western. As a percentage of revenues, combined gross profit increased from
28.3% in 1995 to 28.5% in 1996. Gross profit as a percentage of revenues at
Atlas increased from 12.5% of revenues in 1995 to 16.5% of revenues in 1996 as
increasing demand for Atlas' specialized installation services enabled Atlas to
earn higher margins. Gross profit as a percentage of revenues at Accurate
decreased from 26.1% of revenues in 1995 to 21.0% of revenues in 1996 as a
result of an increase in overtime and subcontract labor necessary to support the
increased number of "design and build" projects. Gross profit as a percentage
of revenues at Western increased from 17.1% to 28.2% from 1995 to 1996, which
resulted in part from Western's participation in an incentive program sponsored
by the Public Service Company of Colorado during 1996. Western does not intend
to participate in this program during 1997.

SELLING, GENERAL AND ADMINISTRATIVE EXPENSES. Combined selling, general
and administrative expenses increased $3.4 million, or 10.8%, from $31.0 million
in 1995 to $34.4 million in 1996. Selling, general and administrative expenses
increased $1.4 million at Lawrence, approximately one-half of which was related
to increases in salary and incentive compensation paid to the owners, and the
other half of which was related to increases in incentive compensation and
discretionary profit sharing contributions for employees. Selling, general and
administrative expenses increased $0.7 million at Tri-City as a result of a $1.1
million increase in compensation to the owners in lieu of S Corporation
distributions, offset by $0.4 million of reductions in other overhead expenses.
As a percentage of combined revenues, selling, general and administrative
expenses decreased from 21.2% in 1995 to 20.5% in 1996.

COMBINED RESULTS FOR 1995 COMPARED TO 1994

REVENUES. Combined revenues increased approximately $21.8 million, or
17.5%, from $124.7 million in 1994 to $146.5 million in 1995, primarily due to
an increase in commercial and industrial "design and build" revenues of
approximately 40% and an increase of approximately 10% in maintenance, repair
and replacement revenues. Revenues at Quality increased $8.2 million from 1994
to 1995 as a result of management's focus on obtaining more "design and build"
projects and related service work. Revenues at Tri-City increased $8.1 million
from 1994 to 1995 as a result of a strategy implemented in late 1994 to focus on
larger "design and build" projects and the related service relationships. To
accomplish its strategy, Tri-City increased the size of its sales and project
management staff.

GROSS PROFIT. Combined gross profit increased $9.1 million, or 28.0%, from
$32.4 million in 1994 to $41.5 million in 1995. Gross profit increased $3.1
million at Tri-City and $2.9 million at Quality. As a percentage of revenues,
combined gross profit increased from 26.0% in 1994 to 28.3% in 1995. Gross
profit as a percentage of revenues at Tri-City increased from 15.5% in 1994 to
22.9% in 1995 as a result of an increase in the number of higher-margin "design
and build" installation projects. Gross profit as a percentage of revenues at
Lawrence increased from 23.2% in fiscal 1994 to 27.3% in fiscal 1995 as
management emphasized higher-margin "design and build" projects and
successfully implemented an incentive program for project managers to control
project costs.

SELLING, GENERAL AND ADMINISTRATIVE EXPENSES. Combined selling, general
and administrative expenses increased $3.6 million, or 13.3%, from $27.4 million
in 1994 to $31.0 million in 1995. Selling, general and

22
<PAGE>
administrative expenses increased $1.0 million at Tri-City from 1994 to 1995
primarily due to a $0.8 million increase in compensation to its owners. Selling,
general and administrative expenses at Lawrence increased $0.6 million primarily
due to an increase in salary and incentive compensation to its owners. As a
percentage of combined revenues, combined selling, general and administrative
expenses decreased from 22.0% in 1994 to 21.2% in 1995.

COMBINED LIQUIDITY AND CAPITAL RESOURCES

During the six months ended June 30, 1997, net cash provided by operating
activities was $4.8 million, capital expenditures were $1.1 million and net
borrowings of debt amounted to $11.8 million. Additionally, payments for S
Corporation Distributions were $20.6 million. At June 30, 1997, the combined
Founding Companies had working capital of $21.4 million and total debt of $20.5
million, including $1.9 million of debt to stockholders.

In connection with and prior to the Mergers, certain Founding Companies
made S Corporation Distributions to their owners of substantially all of their
previously-taxed undistributed earnings. The pro forma combined financial
statements as of March 31, 1997 and for the three months then ended, included
elsewhere in this Prospectus, reflect pro forma adjustments for the estimated
amount of these S Corporation Distributions and additional debt needed to fund
these distributions had they occurred in their entirety as of March 31, 1997.
These pro forma adjustments reflect $16.8 million of S Corporation Distributions
and $11.0 million of additional debt.

On a combined basis, the Founding Companies generated $9.0 million of net
cash from operating activities during fiscal 1996, primarily at Quality,
Tri-City and CSI/Bonneville. Net cash used in investing activities was $3.0
million on a combined basis, primarily for equipment purchases. Net cash used in
financing activities was $7.3 million on a combined basis, consisting of net
reductions in long-term debt of $1.6 million and distributions to stockholders
of $5.7 million. At December 31, 1996, the combined Founding Companies had
working capital of $18.9 million and total debt of $8.6 million, including debt
to stockholders.

The Company intends to pursue acquisition opportunities. The Company
expects to fund future acquisitions through the issuance of additional Common
Stock, borrowings, including use of amounts available under its credit facility
executed in connection with the IPO and cash flow from operations. The Company
anticipates that its cash flow from operations will provide cash in excess of
the Company's normal working capital needs, debt service requirements and
planned capital expenditures for equipment. On a combined basis, the Founding
Companies made capital expenditures of $2.3 million in fiscal 1996.

The Company has obtained a revolving line of credit of $75.0 million from
Bank One. The facility will be used for acquisitions, capital expenditures,
refinancing of debt not paid out of the proceeds of the IPO and for general
corporate purposes. The credit facility requires the Company to comply with
various loan covenants including (i) maintenance of certain financial ratios,
(ii) restrictions on additional indebtedness, and (iii) restrictions on liens,
guarantees, advances and dividends. As of October 31, 1997, borrowings under the
line of credit were $17.3 million, which was used to repay existing indebtedness
of the Founding Companies.

QUALITY RESULTS OF OPERATIONS

Quality, headquartered in Grand Rapids, Michigan, was founded in 1968 and
operates primarily throughout western Michigan. Quality focuses on providing
"design and build" installation services and maintenance, repair and
replacement of HVAC systems, primarily for medium and large commercial
facilities.

(1) The financial data for the year ended December 31, 1996 and the year ended
March 31, 1996 both include results for the three months ended March 31,
1996, which were as follows: revenues of $6.3 million, cost of services of
$4.3 million and selling, general and administrative expenses of $1.6
million.

QUALITY RESULTS FOR SIX MONTHS ENDED JUNE 30, 1997 COMPARED TO SIX MONTHS
ENDED JUNE 30, 1996

REVENUES. Revenues increased $1.4 million, or 8.8%, from $15.4 million for
the six months ended June 30, 1996 to $16.7 million for the six months ended
June 30, 1997 due to broad based growth in its commercial "design and build"
installation activity and maintenance, repair and replacement revenues.

GROSS PROFIT. Gross profit increased $1.3 million, or 23.6%, from $5.6
million for the six months ended June 30, 1996 to $6.9 million for the six
months ended June 30, 1997. As a percentage of revenues, gross profit increased
from 36.2% to 41.2%. Quality's gross margin improved due to increasing demand
for its services in its market and because its gross margin during the first
half of 1996 was somewhat lower due to narrower margins on a large automotive
"design and build" installation it completed in the second quarter of 1996.

SELLING, GENERAL AND ADMINISTRATIVE EXPENSES. Selling, general and
administrative expenses increased $0.7 million, or 21.8%, from $3.2 million for
the six months ended June 30, 1996 to $3.9 million for the six months ended June
30, 1997. The increase in selling, general and administrative expenses was
primarily attributable to additions in personnel and infrastructure to support
the growth in commercial "design and build" installation activity. As a
percentage of revenues, selling, general and administrative expenses increased
from 20.7% to 23.2%.

QUALITY RESULTS FOR NINE MONTHS ENDED DECEMBER 31, 1996 COMPARED TO NINE MONTHS
ENDED DECEMBER 31, 1995

REVENUES. Revenues decreased $3.0 million, or 11.4%, from $26.3 million
for the nine months ended December 31, 1995 to $23.3 million for the nine months
ended December 31, 1996 due to a decrease in Quality's volume of commercial
"design and build" installation projects. Quality's decline in revenues from
1995 to 1996 resulted from management's decision to be more selective in
accepting installation projects. Management continues to emphasize project
selectivity and expansion of capacity through the addition of technical staff
and management rather than through subcontract labor and employee overtime.

GROSS PROFIT. Gross profit decreased $0.6 million, or 6.3%, from $9.7
million for the nine months ended December 31, 1995 to $9.1 million for the nine
months ended December 31, 1996. As a percentage of revenues, gross profit
increased from 37.0% to 39.1% due to management's emphasis on project selection
and a decrease in the use of subcontract labor, employee overtime and outside
services.

SELLING, GENERAL AND ADMINISTRATIVE EXPENSES. Selling, general and
administrative expenses decreased $0.2 million, or 2.9%, from $5.2 million for
the nine months ended December 31, 1995 to $5.0 million for the nine months
ended December 31, 1996. As a percentage of revenues, these expenses increased
from 19.7% to 21.6% due to the decline in revenues.

QUALITY RESULTS FOR YEAR ENDED DECEMBER 31, 1996 COMPARED TO YEAR ENDED MARCH
31, 1996

REVENUES. Revenues decreased $3.0 million, or 9.2%, from $32.6 million for
the year ended March 31, 1996 to $29.6 million for the year ended December 31,
1996, for the reasons described above.

24
<PAGE>
GROSS PROFIT. Gross profit decreased $0.6 million, or 5.2%, from $11.7
million for the year ended March 31, 1996 to $11.1 million for the year ended
December 31, 1996. As a percentage of revenues, gross profit increased from
36.0% to 37.6% due to management's emphasis on project selection and a decrease
in the use of subcontract labor, employee overtime and outside services.

SELLING, GENERAL AND ADMINISTRATIVE EXPENSES. Selling, general and
administrative expenses decreased $0.2 million, or 2.2%, from $6.8 million for
the year ended March 31, 1996 to $6.6 million for the year ended December 31,
1996. As a percentage of revenues, selling, general and administrative expenses
increased from 20.8% to 22.4% due to the decline in revenues.

QUALITY RESULTS FOR YEAR ENDED MARCH 31, 1996 COMPARED TO YEAR ENDED MARCH 31,
1995

REVENUES. Revenues increased $8.2 million, or 33.4%, from $24.4 million
for the fiscal year ended March 31, 1995 to $32.6 for the fiscal year ended
March 31, 1996. This increase in revenues was primarily attributable to
management's emphasis on obtaining more "design and build" installation
projects and the related service work.

GROSS PROFIT. Gross profit increased $2.9 million, or 33.5%, from $8.8
million for the fiscal year ended March 31, 1995 to $11.7 million for the fiscal
year ended March 31, 1996. As a percentage of revenues, gross profit remained
unchanged at 36.0% as the benefits associated with higher revenues were offset
by an increase in subcontract labor, employee overtime and outside services.

SELLING, GENERAL AND ADMINISTRATIVE EXPENSES. Selling, general and
administrative expenses increased $0.2 million, or 2.2%, from $6.6 million for
the fiscal year ended March 31, 1995 to $6.8 million for the fiscal year ended
March 31, 1996. As a percentage of revenues, selling, general and administrative
expenses decreased from 27.2% to 20.8% as the Company successfully leveraged its
infrastructure to support the significant increase in volume.

QUALITY LIQUIDITY AND CAPITAL RESOURCES

Quality generated $1.9 million in net cash from operating activities for
the six months ended June 30, 1997. Net cash used in investing activities was
approximately $0.2 million, principally from purchases of equipment. Net cash
used in financing activities was $3.8 million, representing borrowings of
long-term debt of $6.1 million and distributions to shareholders of $9.9
million.

At June 30, 1997, Quality had working capital of $6.2 million and $7.4
million of total debt outstanding.

Quality generated $4.5 million in net cash from operating activities for
the twelve months ended December 31, 1996. Net cash used in investing activities
was approximately $0.4 million, principally for equipment purchases. Net cash
used in financing activities was $4.4 million, of which $3.5 million was
distributed to shareholders and $0.9 million was used to repay long-term debt.

At December 31, 1996, Quality had working capital of $4.9 million and $1.3
million of total debt outstanding.

ATLAS RESULTS OF OPERATIONS

Atlas, headquartered in Houston, Texas, was founded in 1947 and operates
primarily in the southwest, northeast and mid-Atlantic regions of the United
States. Atlas is a leading provider of HVAC installation services for apartment
complexes, condominiums, hotels and elder care facilities in the United States

ATLAS RESULTS FOR SIX MONTHS ENDED JUNE 30, 1997 COMPARED TO SIX MONTHS ENDED
JUNE 30, 1996

REVENUES. Revenues decreased $0.5 million, or 3.6%, from $14.5 million for
the six months ended June 30, 1996 to $14.0 million for the six months ended
June 30, 1997.

GROSS PROFIT. Gross profit increased $0.9 million, or 45.4%, from $1.9
million for the six months ended June 30, 1996 to $2.8 million for the six
months ended June 30, 1997. As a percentage of revenues, gross profit increased
from 13.3% to 20.0%. Atlas' gross margin increased as a result of its ability to
be more selective in accepting "design and build" projects for multi-unit
facilities.

TRI-CITY RESULTS FOR SIX MONTHS ENDED JUNE 30, 1997 COMPARED TO SIX MONTHS
ENDED JUNE 30, 1996

REVENUES. Revenues increased $5.8 million, or 51.9%, from $11.2 million
for the six months ended June 30, 1996 to $17.0 million for the six months ended
June 30, 1997 due primarily to two "design and build" installation projects.
One of these projects is for a nationally-known healthcare organization, and
represents the first major facility on what is expected to be a medical campus
covering more than 100 acres. Tri-City pursued this project to expand its
presence in its regional healthcare HVAC market. Tri-City was

27
<PAGE>
selected as the lead mechanical contractor on this project. Installation of the
HVAC and process piping systems on this project began in October 1996 and
accounted for approximately 48% of the revenues in the six months ended June 30,
1997.The second project is at a new fabrication facility for a major
semiconductor manufacturer.

GROSS PROFIT. Gross profit decreased $0.3 million, or 10.6%, from $2.8
million for the six months ended June 30, 1996 to $2.5 million for the six
months ended June 30, 1997. As a percentage of revenues, gross profit decreased
from 24.8% to 14.6%. In its role as lead mechanical contractor on this major
healthcare project Tri-City is responsible for arranging a significant amount of
subcontract work as well as for procuring most of the HVAC equipment on this
project. Margins on subcontract work and procured equipment are typically lower
than margins on work performed directly by Tri-City.

SELLING, GENERAL AND ADMINISTRATIVE EXPENSES. Selling, general and
administrative expenses decreased $0.6 million, or 32.1%, from $2.0 million for
the six months ended June 30, 1996 to $1.3 million for the six months ended June
30, 1997 due to a decrease in owners' compensation. This decrease was partially
offset by an increase in personnel and infrastructure to support growth in their
commercial "design and build" installation activity. As a percentage of
revenues, selling, general and administrative expenses decreased from 17.7% to
7.9% due to the decrease in owners' compensation.

TRI-CITY RESULTS FOR YEAR ENDED DECEMBER 31, 1996 COMPARED TO YEAR ENDED
DECEMBER 31, 1995

REVENUES. Revenues decreased $0.8 million, or 3.2%, from $25.0 million in
1995 to $24.2 million in 1996, primarily due to a decrease in "plan and spec"
revenues from 1995 to 1996 of approximately $2.0 million, partially offset by an
increase of approximately $1.2 million in commercial HVAC maintenance, repair
and replacement service revenues.

GROSS PROFIT. Gross profit remained constant at $5.7 million for 1995 and
1996. As a percentage of revenues, gross profit increased from 22.9% to 23.4%,
due to a decrease in lower margin "plan and spec" projects in 1996.

SELLING, GENERAL AND ADMINISTRATIVE EXPENSES. Selling, general and
administrative expenses increased $0.7 million, or 22.2%, from $3.2 million in
1995 to $3.9 million in 1996 due to a $1.1 million increase in compensation to
owners in lieu of S Corporation distributions, offset by a $0.4 million
reduction in other overhead expenses. As a percentage of revenues, selling,
general and administrative expenses increased from 12.8% in 1995 to 16.1% in
1996, primarily as a result of the increase in owners' compensation.

TRI-CITY RESULTS FOR YEAR ENDED DECEMBER 31, 1995 COMPARED TO YEAR ENDED
DECEMBER 31, 1994

REVENUES. Revenues increased $8.1 million, or 48.2%, from $16.9 million in
1994 to $25.0 million in 1995 as a result of a strategy implemented in 1994 to
emphasize "design and build" projects. To implement its strategy, Tri-City
increased its sales and project management staff.

GROSS PROFIT. Gross profit increased $3.1 million, or 119.4%, from $2.6
million in 1994 to $5.7 million in 1995. As a percentage of revenues, gross
profit increased from 15.5% in 1994 to 22.9% in 1995 as a result of an increase
in the proportion of "design and build" installation projects.

SELLING, GENERAL AND ADMINISTRATIVE EXPENSES. Selling, general and
administrative expenses increased $1.0 million, or 43.9%, from $2.2 million in
1994 to $3.2 million in 1995. The increase in selling, general and
administrative expenses in 1995 was primarily attributable to a $0.8 million
increase in compensation to owners in lieu of S Corporation distributions and an
increase in the number of the sales personnel and project managers. As a
percentage of revenues, selling, general and administrative expenses decreased
from 13.2% in 1994 to 12.8% in 1995 as Tri-City was able to substantially
increase its volume without a commensurate increase in overhead expenses.

TRI-CITY LIQUIDITY AND CAPITAL RESOURCES

Tri-City generated $1.8 million in net cash from operating activities for
the six months ended June 30, 1997. Net cash provided by investing activities
was $0.5 million from the sale of investments. Net cash used in financing

SEASONAL AND CYCLICAL NATURE OF THE HVAC INDUSTRY

The HVAC industry is subject to seasonal variations. Specifically, the
demand for new installations is generally lower during the winter months due to
reduced construction activities during inclement weather and less use of air
conditioning during the colder months. Demand for HVAC services is generally
higher in the second and third quarters due to the increased use of air
conditioning during the warmer months. Accordingly, the Company expects its
revenues and operating results generally will be lower in the first and fourth
quarters. Historically, the construction industry has been highly cyclical. As a
result, the Company's volume of business may be adversely affected by declines
in new installation projects in various geographic regions of the United States.

INFLATION

Inflation did not have a significant effect on the results of operations of
the combined Founding Companies for 1994, 1995 or 1996 or the six months ended
June 30, 1997.

37
<PAGE>
BUSINESS

Comfort Systems was founded in 1996 to become a leading national provider
of comprehensive HVAC installation services and maintenance, repair and
replacement of HVAC systems, focusing primarily on the commercial and industrial
markets. The Company's commercial and industrial applications include office
buildings, retail centers, apartment complexes, hotels, manufacturing plants and
government facilities. The Company also provides specialized HVAC applications
such as process cooling, control systems, electronic monitoring and process
piping. Approximately 90% of the Company's pro forma combined 1996 revenues of
$167.5 million was derived from commercial and industrial customers, with
approximately 53% of combined revenues attributable to installation services and
47% attributable to maintenance, repair and replacement services.

INDUSTRY OVERVIEW

Based on available industry data, the Company believes that the HVAC
industry is highly fragmented with over 40,000 companies, most of which are
small, owner-operated businesses with limited access to capital for
modernization and expansion. The overall HVAC industry, including the
commercial, industrial and residential markets, is estimated to generate annual
revenues in excess of $75 billion, over $35 billion of which is in the
commercial and industrial markets. HVAC systems have become a necessity in
virtually all commercial and industrial buildings as well as homes. Because most
commercial buildings are sealed, HVAC systems provide the primary method of
addressing air quality concerns and injecting fresh air. Older industrial
facilities often have poor air quality as well as inadequate air conditioning,
factors which are causing industrial facility owners to consider replacement
options. Operation of older HVAC systems represents a significant cost due to
their energy inefficiency. In many instances, the replacement of an aging system
with a modern, energy-efficient system will significantly reduce a building's
operating costs while also improving the effectiveness of the HVAC system and
air quality.

Growth in the HVAC industry is being positively affected by a number of
factors, particularly (i) the aging of the installed base, (ii) the increasing
efficiency, sophistication and complexity of HVAC systems and (iii) the
increasing restrictions on the use of refrigerants commonly used in older HVAC
systems. These factors are expected to increase demand for the reconfiguration
or replacement of existing HVAC systems. These factors also mitigate the effect
on the HVAC industry of the cyclicality inherent in the traditional construction
industry.

The HVAC industry can be broadly divided into the installation segment and
the maintenance, repair and replacement segment.

INSTALLATION SEGMENT. The installation segment consists of "design and
build" and "plan and spec" projects. In "design and build" projects, the
commercial HVAC firm is responsible for designing, engineering and installing a
cost-effective, energy-efficient system customized to meet the specific needs of
the building owner. Costs and other project terms are normally negotiated
between the building owner or its representative and the HVAC firm. Firms which
specialize in "design and build" projects generally have specially-trained
HVAC engineers, CAD/CAM design systems, in-house sheet metal and prefabrication
capabilities. These firms utilize a consultative approach with customers and
tend to develop long-term relationships with building owners and developers,
general contractors, architects and property managers. "Plan and spec"
installation refers to projects where an architect or a consulting engineer
designs the HVAC system and the installation project is put out for bid. The
Company believes that "plan and spec" projects usually take longer to complete
than "design and build" projects because the preparation of the system design
and the bid process often take months to complete. Furthermore, in "plan and
spec" projects, the HVAC firm is not responsible for project design and changes
must be approved by several parties, thereby increasing overall project time and
cost.

MAINTENANCE, REPAIR AND REPLACEMENT SEGMENT. This segment includes the
maintenance, repair, replacement, reconfiguration and monitoring of previously
installed HVAC systems and controls. Growth in this segment has been fueled by
the aging of the installed base of HVAC systems and the increasing demand for
more efficient, sophisticated and complex systems and controls. The increasing
sophistication

38
<PAGE>
and complexity of these HVAC systems is leading many commercial and industrial
building owners and property managers to outsource maintenance and repair, often
through service agreements with HVAC service providers. In addition, increasing
restrictions are being placed on the use of certain types of refrigerants used
in HVAC systems, which, along with air quality concerns, are expected to
increase demand for the reconfiguration and replacement of existing HVAC
systems. State-of-the-art control and monitoring systems feature electronic
sensors and microprocessors and require specialized training to install,
maintain and repair, which the typical building engineer does not have.
Increasingly, HVAC systems in commercial and industrial buildings are being
remotely monitored through PC-based communications systems to improve energy
efficiency and expedite problem diagnosis and correction.

The Company believes that the majority of business owners in the HVAC
industry have limited access to capital for expansion of their businesses and
that few have attractive liquidity options. In addition, the increasing
complexity of HVAC systems has led to a need for better trained technicians to
install, monitor and service these systems. The cost of recruiting, training and
retaining a sufficient number of qualified technicians makes it more difficult
for smaller HVAC companies to expand their businesses. The Company believes that
significant opportunities exist for a well-capitalized, national company
operating in the commercial, industrial and residential markets of the HVAC
industry and that the highly fragmented nature of this industry should allow it
to consolidate existing HVAC businesses.

STRATEGY

The Company plans to achieve its goal of becoming a leading national
provider of comprehensive HVAC services by implementing its operating strategy,
emphasizing continued internal growth and expanding through acquisitions.

OPERATING STRATEGY. The Company believes there are significant
opportunities to increase the profitability of the Founding Companies and
subsequently acquired businesses. The key elements of the Company's operating
strategy are:

FOCUS ON COMMERCIAL AND INDUSTRIAL MARKETS. The Company intends to
focus principally on the commercial and industrial markets with particular
emphasis on the "design and build" installation and the maintenance,
repair and replacement segments. The Company believes that the commercial
and industrial HVAC markets are attractive because of their growth
opportunities, diverse customer base, attractive margins and potential for
long-term relationships with building owners and managers, general
contractors and architects.

OPERATE ON DECENTRALIZED BASIS. The Company intends to manage the
Founding Companies on a decentralized basis, with local management assuming
responsibility for the day-to-day operations, profitability and growth of
the business. The Company believes that, while maintaining strong operating
and financial controls, a decentralized operating structure will retain the
entrepreneurial spirit present in each of the acquired companies and will
allow the Company to capitalize on the considerable local and regional
market knowledge and customer relationships possessed by each acquired
company.

ACHIEVE OPERATING EFFICIENCIES. The Company believes there are
significant opportunities to achieve operating efficiencies and cost
savings through purchasing economies and the adoption of "best practices"
operating programs. The Company intends to use its increased purchasing
power to gain volume discounts in areas such as HVAC components, raw
materials, service vehicles, advertising, bonding and insurance. Moreover,
the Company will review its operations and training programs at the local
and regional operating levels in order to identify those "best practices"
that can be successfully implemented throughout its operations.

39
<PAGE>
INTERNAL GROWTH. A key component of the Company's strategy is to continue
the internal growth at the Founding Companies and subsequently acquired
businesses. The key elements of the Companys internal growth strategy are:

CAPITALIZE ON SPECIALIZED TECHNICAL AND MARKETING STRENGTHS. The
Company believes it will be able to expand the services it offers in its
markets by leveraging the specialized technical and marketing strengths of
individual acquired companies. For example, one of the acquired companies
has developed significant industry recognition for its technical expertise
within apartment complexes, condominiums, hotels and elder care facilities
which may be transferable to other acquired companies. A number of acquired
companies currently focus primarily on installation and, therefore, have
only limited maintenance, repair and replacement operations. The Company
believes there are significant opportunities for these acquired companies
to provide maintenance, repair and replacement services, particularly by
offering those services to its "design and build" customers. Several of
the acquired companies have specific expertise in HVAC control and
monitoring systems, process cooling, replacement and other service
strengths, many of which can be shared with other acquired companies and
subsequently acquired businesses.

ESTABLISH NATIONAL MARKET COVERAGE. The Company believes that
significant demand exists from large national companies to utilize the
services of a single HVAC service company capable of providing
comprehensive commercial and industrial services on a regional or national
basis. Many of the acquired companies already provide local or regional
coverage to companies with nationwide locations, such as commercial real
estate developers and managers, retailers and manufacturers. The Company
believes these existing relationships can be expanded as it develops a
nationwide network since these customers often desire a single source for
all of their HVAC needs to promote consistency, improve control and reduce
cost.

ACQUISITIONS. The Company believes the HVAC industry is highly fragmented
with over 40,000 companies, most of which are small, owner-operated businesses
with limited access to adequate capital for modernization and expansion. The key
elements of the Company's acquisition strategy are:

ENTER NEW GEOGRAPHIC MARKETS. In new markets, the Company intends to
target one or more leading local or regional companies providing HVAC or
complementary services. The acquisition target will have the customer base,
technical skills and infrastructure necessary to be a core business into
which other HVAC service operations can be consolidated. The Company will
choose businesses that are located in attractive markets, are financially
stable, are experienced in the industry and have management willing to
participate in the future growth of the Company.

EXPAND WITHIN EXISTING MARKETS. Once the Company has entered a
market, it will seek to acquire other well-established HVAC businesses to
expand its market penetration and range of services offered. The Company
also will pursue "tuck-in" acquisitions of smaller companies, whose
operations can be integrated into an existing Company operation to leverage
the existing infrastructure.

ACQUIRE COMPLEMENTARY BUSINESSES. The Company will focus on its
traditional markets in the HVAC industry and may acquire companies
providing complementary services to the same customer base, such as
commercial and industrial process piping and plumbing as well as electrical
companies. This will enable the Company to offer, on a comprehensive basis
and from a single provider, HVAC, mechanical and electrical services in
certain markets.

ACQUISITION PROGRAM

The Company believes it will be regarded by acquisition candidates as an
attractive acquirer because of: (i) the Company's strategy for creating a
national, comprehensive and professionally managed HVAC service provider that
capitalizes on cross-marketing and business development opportunities; (ii) the
Company's decentralized operating strategy; (iii) the Company's increased
visibility and access to financial resources as a public company; (iv) the
potential for increased profitability due to certain centralized administrative
functions, enhanced systems capabilities and access to increased marketing
resources; and

40
<PAGE>
(v) the potential for the owners of the businesses being acquired to participate
in the Company's planned internal growth and growth through acquisitions, while
realizing liquidity.

As consideration for future acquisitions, the Company intends to use
various combinations of its Common Stock, cash and notes. The consideration for
each future acquisition will vary on a case-by-case basis. The major factors in
establishing the purchase price for each acquisition will be historical
operating results, future prospects of the acquiree and the ability of that
business to complement the services offered by the Company. Management believes
that companies providing commercial and industrial HVAC services are larger than
those providing residential services, with commercial and industrial companies
generating annual revenues ranging from $5 million to $35 million, compared to
companies providing residential HVAC services which generally have annual
revenues ranging from $500,000 to $3 million.

OPERATIONS AND SERVICES PROVIDED

The Company provides a wide range of installation, maintenance, repair and
replacement services for HVAC systems in commercial, industrial and residential
properties. Daily operations are managed on a local basis by the management team
at each acquired company. In addition to senior management, the acquired
companies' personnel generally include design engineers, sales personnel,
customer service personnel, installation service technicians, sheet metal and
prefabrication technicians, estimators and administrative personnel. The Company
manages the acquired companies on a decentralized basis, with local management
being responsible for day-to-day operating decisions. The Company intends to
centralize certain administrative functions to enable the management of each
acquired company to focus on pursuing new business opportunities and to improve
operating efficiencies. Administrative functions which the Company expects to
centralize include Company-wide training and safety programs, accounting
programs, risk management programs, purchasing programs and employee benefits.

INSTALLATION SEGMENT. The Company's installation business comprised
approximately 53% of the Company's 1996 revenues. This segment consists of the
design, engineering, integration, installation and start-up of HVAC systems. The
commercial and industrial installation services performed by the Company consist
primarily of "design and build" systems for office buildings, retail centers,
apartment complexes, hotels, manufacturing plants and government facilities. In
a "design and build" project, the customer typically has an overall design for
the facility prepared by an architect or a consulting engineer who then enlists
the Company's sales and engineering personnel to prepare a specific design for
the HVAC system. The Company determines the needed capacity, energy efficiency
and type of controls that best suit the proposed facility. The Company's
engineer then estimates the amount of time, labor, materials and equipment
needed to build the specified system. Materials and equipment for a typical
commercial or industrial project include ductwork, compressors, blowers,
chillers, cooling towers, air handling equipment and the associated pumps and
piping necessary to complete the system. The Company utilizes CAD/CAM systems in
the design and engineering phases of the project to calculate the material and
labor costs of the project based on previously established Company standards and
to generate mechanical drawings for each project. The drawings are prepared in a
format appropriate for submission to local building inspectors. The final
design, terms, price and timing of the project are then negotiated with the
customer or its representatives, after which any necessary modifications are
made to the system.

Once an agreement has been reached, the Company orders the necessary
materials and equipment for delivery to meet the project schedule. In most
instances, the Company fabricates in its own facilities the ductwork and piping
and assembles certain components for the system based on the mechanical drawing

41
<PAGE>
specifications, thereby eliminating the need to subcontract ductwork or piping
fabrication. The Company's CAD/CAM systems are capable of automatically cutting
ductboard, sheet metal and piping, thereby reducing the amount of labor
necessary to produce the ductwork and piping for the system. Project specific
components are then fabricated at the Company's facilities in sections small
enough to be transported to the job site. This enables the Company to limit the
amount of field work required for installation, reduce the labor associated with
the actual installation process and meet the shorter time requirements
increasingly demanded by commercial and industrial customers. The Company
installs the system at the project site, working closely with the general
contractor. Most commercial and industrial installation projects last from two
weeks to one year and generate revenues from $25,000 to $2,000,000 per project.
These projects are generally billed periodically as costs are incurred
throughout the project, with a 10% retainage until completion and successful
start-up of the HVAC system.

The Company also performs selected "plan and spec" installation services
when a bidder prequalification process has been used by the customer to limit
the number of potential bidders for an attractive project. The Company may use
these projects when "design and build" projects are in lower demand and to
provide additional on-the-job training to apprentice or less-experienced
technicians.

The Company also installs process cooling systems, control and monitoring
systems and industrial process piping. Process cooling systems are utilized
primarily in industrial facilities to provide heating and/or cooling to precise
temperature and climate standards for products being manufactured and for the
manufacturing equipment. Control systems are used in HVAC and process cooling
systems in order to maintain pre-established temperature or climate standards
for commercial or industrial facilities. These systems use direct digital
technology integrated with computer terminals. HVAC control systems are capable
not only of controlling a facility's entire HVAC system, often on a room-by-room
basis, but can be programmed to integrate energy management, security, fire,
card key access, lighting and overall facility monitoring. Monitoring can be
performed on-site or remotely through a PC-based communications system. The
monitoring system will sound an alarm when the HVAC system is operating outside
pre-established parameters. Diagnosis of potential problems can be performed
from the computer terminal which often can remotely adjust the control system.
Industrial process piping is utilized in manufacturing facilities to convey
required raw materials, support utilities and finished products.

The Company's residential services consist of installing complete central
HVAC systems in new and existing homes, often through agreements with housing
developers. In 1996, residential installation comprised approximately 2% of the
Company's revenues.

The Company's subsidiaries generally warrant their labor for the first
year after installation on new HVAC systems and for 30 days after servicing of
existing HVAC systems. A reserve for warranty costs is recorded based on a
percentage of material costs.

MAINTENANCE, REPAIR AND REPLACEMENT SEGMENT. The Company's maintenance,
repair and replacement segment comprised approximately 47% of the Company's 1996
combined revenues and includes the maintenance, repair, replacement,
reconfiguration and monitoring of HVAC systems and industrial process piping.
Over one-half of the Company's maintenance, repair and replacement segment
revenues were derived from reconfiguring existing HVAC systems for commercial
and industrial customers. Reconfiguration often utilizes consultative expertise
similar to that provided in the "design and build" installation market. The
Company believes that the reconfiguration of an existing system results in a
more cost-effective, energy-efficient system that better meets the specific
needs of the building owner. The reconfiguration also enables the Company to
utilize its design and engineering personnel as well as its sheet metal and
pre-fabrication facilities.

42
<PAGE>
Maintenance and repair services are provided either in response to service
calls or pursuant to a service agreement. Service calls are coordinated by
customer service representatives or dispatchers that use computer and
communications technology to process orders, arrange service calls, communicate
with customers, dispatch technicians and invoice customers. Service technicians
work out of service vans equipped with commonly used parts, supplies and tools
to complete a variety of jobs.

Commercial and industrial service agreements usually have terms of one to
three years, with automatic annual renewals, and typically provide fees from
$3,000 to $20,000 per year. The Company also provides remote monitoring of
temperature, pressure, humidity and air flow for HVAC systems for commercial and
industrial customers. If the system is not operating within the specifications
set forth by the customer and cannot be remotely adjusted, a service crew is
dispatched to analyze and repair the system, as appropriate. Residential service
agreements generally have one year terms, automatic renewal provisions and
provide annual fees between $100 and $200 per system.

SOURCES OF SUPPLY

The raw materials and components used by the Company include HVAC system
components, ductwork, steel, sheet metal and copper tubing and piping. These raw
materials and components are generally available from a variety of domestic or
foreign suppliers at competitive prices. Delivery times are typically short for
most raw materials and standard components, but during periods of peak demand
may take a month or more to obtain. Chillers for large units typically have the
longest delivery time and generally have lead times of up to six months. The
major components of HVAC systems are compressors and chillers that are
manufactured primarily by York Heating and Air Conditioning Corporation
("York"), Carrier Corporation and Trane Air Conditioning Company. The major
suppliers of control systems are Honeywell Inc., Johnson Controls Inc., York and
Andover Control Corporation. The Company believes that it will be able to reduce
costs on raw materials and components through volume purchases. The Company does
not currently have any significant contracts for the supply of raw materials or
components.

SALES AND MARKETING

The Company has a diverse customer base, with no single customer accounting
for more than 4% of the Company's pro forma combined 1996 revenues. Management
and a dedicated sales force at the acquired companies have been responsible for
developing and maintaining successful long-term relationships with key
customers. Customers of the acquired companies generally include building owners
and developers and property managers, as well as general contractors, architects
and consulting engineers. The Company intends to continue its emphasis on
developing and maintaining long-term relationships with its customers by
providing superior, high-quality service in a professional manner. Moreover, the
dedicated sales force will receive additional technical and sales training to
enhance the comprehensive selling skills necessary to serve the HVAC needs of
its customers.

The Company also intends to capitalize on cross-marketing and business
development opportunities that management believes will be available to the
Company as a national provider of comprehensive commercial, industrial and
residential HVAC services. Management believes that it will be able to leverage
the diverse technical and marketing strengths of individual acquired companies
to expand the services offered in other local markets. Eventually, the Company
intends to offer comprehensive services from many of its regional locations.

EMPLOYEES

As of September 30, 1997 the Company had 2,156 employees, including 127
management personnel, 1,698 engineers and service and installation technicians,
89 sales personnel and 242 administrative personnel. The Company does not
anticipate any reductions in staff as a result of the recent consolidation of
the Founding Companies. Rather, as it implements its internal growth and
acquisition strategies, the Company expects that the number of employees will
increase. Certain of the Company's subsidiaries have collective bargaining
agreements which cover, in the aggregate, approximately 350 employees. Under
these agreements, these subsidiaries generally make payments to multi-employer
pension plans. The Company

43
<PAGE>
has not experienced any strikes or work stoppages and believes its relationship
with its employees and union representatives is satisfactory.

RECRUITING, TRAINING AND SAFETY

The Company's future success will depend, in part, on its ability to
continue to attract, retain and motivate qualified service technicians, field
supervisors and project managers. The Company believes that its success in
retaining qualified employees will be based on the quality of its recruiting,
training, compensation, employee benefits programs and opportunities for
advancement. The Company recruits at local technical schools and community
colleges where students focus on learning basic HVAC and related skills, and
provides on-the-job training, apprenticeship programs, improved benefit
packages, steady employment and opportunities for advancement.

The Company intends to establish "best practices" throughout its
operations to ensure that all technicians comply with safety standards
established by the Company, its insurance carriers and federal, state and local
laws and regulations. The Company's employment screening process seeks to
determine that prospective employees have the requisite skills, sufficient
background references and acceptable driving records, if applicable. The Company
believes that these employment criteria effectively identify potential employees
committed to safety and quality. Additionally, the Company intends to implement
a "best practices" safety program throughout its operations, which will
provide employees with incentives to improve safety performance and decrease
workplace accidents. The Company intends to implement job site safety meetings
and instruct personnel in proper lifting techniques and eye safety in an effort
to reduce the number of preventable accidents.

FACILITIES AND VEHICLES

All of the Company's facilities are leased. See "Certain
Transactions -- Leases of Real Property by Founding Companies." The Company
believes that its facilities are sufficient for its current needs. The Company
operates a fleet of more than 750 owned or leased service trucks, vans and
support vehicles. It believes these vehicles generally are well-maintained and
adequate for the Company's current operations. The Company leases its principal
executive and administrative offices in Houston, Texas.

RISK MANAGEMENT, INSURANCE AND LITIGATION

The primary risks in the Company's operations are bodily injury, property
damage and injured workers' compensation. The Company has obtained and intends
to maintain liability insurance for bodily injury and third party property
damage which it considers sufficient to insure against these risks, subject to
self-insured amounts.

The Company is, from time to time, a party to litigation arising in the
normal course of its business, most of which involves claims for personal injury
and property damage incurred in connection with its operations. The Company is
not currently involved in any litigation, nor is the Company aware of any
threatened litigation, that the Company believes is likely to have a material
adverse effect on its financial condition or results of operations.

The Company generally offers one year warranties on labor it performs and
passes to the customer warranties on equipment purchased from manufacturers. The
Company does not expect warranty claims to have a material effect on its results
of operations or financial condition.

COMPETITION

The HVAC industry is highly competitive. The Company believes that
purchasing decisions in the commercial and industrial markets are based on (i)
long-term customer relationships, (ii) quality, timeliness and reliability of
services provided, (iii) competitive price, (iv) range of services provided, and
(v) scale of operation. The Company believes its strategy of becoming a leading
national provider of comprehensive HVAC installation services as well as
maintenance, repair and replacement of HVAC systems directly addresses these
factors. Specifically, the Company's strategy to focus on the highly
consultative "design and build" installation segment and the maintenance,
repair and replacement segment, as well as its strategy

44
<PAGE>
to operate on a decentralized basis, should promote the development and
strengthening of long-term customer relationships. In addition, the Company's
focus on attracting, training and retaining quality employees by utilizing
professionally managed recruiting, training and benefits programs should allow
it to offer high quality, comprehensive HVAC services at a competitive price.

Most of the Company's competitors are small, owner-operated companies that
typically operate in a limited geographic area. There are a few public companies
focused on providing HVAC services in some of the same services lines provided
by the Company. In addition, there are a number of private companies attempting
to consolidate HVAC companies on a regional or national basis. In the future,
competition may be encountered from new entrants, such as public utilities and
HVAC manufacturers. Certain of the Company's competitors and potential
competitors may have greater financial resources than the Company to finance
acquisition and development opportunities, to pay higher prices for the same
opportunities or to develop and support their own operations.

GOVERNMENTAL REGULATION AND ENVIRONMENTAL MATTERS

The Company's operations are subject to various federal, state and local
laws and regulations, including, (i) licensing requirements applicable to
service technicians, (ii) building and HVAC codes and zoning ordinances, (iii)
regulations relating to consumer protection, including those governing
residential service agreements and (iv) regulations relating to worker safety
and protection of the environment. The Company believes it has all required
licenses to conduct its operations and is in substantial compliance with
applicable regulatory requirements. Failure of the Company to comply with
applicable regulations could result in substantial fines or revocation of the
Company's operating licenses.

Many state and local regulations governing the HVAC services trades require
permits and licenses to be held by individuals. In some cases, a required permit
or license held by a single individual may be sufficient to authorize specified
activities for all the Company's service technicians who work in the state or
county that issued the permit or license. The Company intends to implement a
policy to ensure that, where possible, any such permits or licenses that may be
material to the Company's operations in a particular geographic region are held
by at least two Company employees within that region.

The Company's operations are subject to the federal Clean Air Act, as
amended (the "Clean Air Act"), which governs air emissions and imposes
specific requirements on the use and handling of chlorofluorocarbons ("CFCs")
and certain other refrigerants. Clean Air Act regulations require the
certification of service technicians involved in the service or repair of
equipment containing these refrigerants and also regulate the containment and
recycling of these refrigerants. These requirements have increased the Company's
training expenses and expenditures for containment and recycling equipment. The
Clean Air Act is intended ultimately to eliminate the use of CFCs in the United
States and to require alternative refrigerants to be used in replacement HVAC
systems. As a result, the number of conversions of existing HVAC systems which
use CFCs to systems using alternative refrigerants is expected to increase.

Prior to entering into the agreements relating to the Mergers, the Company
evaluated the properties owned or leased by the acquired companies and engaged
an independent environmental consulting firm to conduct or review assessments of
environmental conditions at these properties. No material environmental problems
were discovered in these reviews, and the Company is not aware of any material
environmental liabilities associated with these properties.

EXECUTIVE COMPENSATION; EMPLOYMENT AGREEMENTS; COVENANTS-NOT-TO-COMPETE

The Company was incorporated in December 1996 and did not pay any of its
executive officers compensation during 1996. The Company anticipates that during
1997 its five most highly compensated executive officers will be Messrs.
Ferreira, Beittenmiller, George, Nothum and Powers.

Each of Messrs. Ferreira, Beittenmiller and George has entered into an
employment agreement with the Company providing for an annual base salary of
$150,000. Each employment agreement is for a term of three years, and unless
terminated or not renewed by the Company or not renewed by the employee, the
term will continue thereafter on a year-to-year basis on the same terms and
conditions existing at the time of renewal. Each of these agreements provides
that, in the event of a termination of employment by the Company without cause,
the employee will be entitled to receive from the Company an amount equal to one
year's salary, payable in one lump sum on the effective date of termination. In
the event of a change in control of the Company (as defined in the agreement)
during the initial three-year term, if the employee is not given at least five
days' notice of such change in control, the employee may elect to terminate his
employment and receive in one lump sum three times the amount he would receive
pursuant to a termination without cause during such initial term. The
non-competition provisions of the employment agreement do not apply to a
termination without such notice. In the event the employee is given at least
five days' notice of such change in control, the employee may elect to terminate
his employment and receive in one lump sum three times the amount he would
receive pursuant to a termination without cause during such initial term. In
such event, the non-competition provisions of the employment agreement would
apply for two years from the effective date of termination. Each employment
agreement contains a covenant not to compete with the Company for a period of
two years immediately following termination of employment or, in the case of a
termination by the Company without cause in the absence of a change in control,
for a period of one year following termination of employment.

Each of Messrs. Nothum and Powers has entered into an employment agreement
with their respective Founding Company providing for an annual base salary of
$150,000. Each employment agreement is for a term of five years, and unless
terminated or not renewed by the Founding Company or not renewed by the
employee, the term will continue thereafter on a year-to-year basis on the same
terms and conditions existing at the time of renewal. Each of these agreements
provides that, in the event of a termination of employment by the Founding
Company without cause during the first three years of the employment term (the
"Initial Term"), the employee will be entitled to receive from the Founding
Company an amount equal to his then current salary for the remainder of the
Initial Term or for one year, whichever is greater. In the event of a
termination of employment with cause during the final two years of the initial
five year term of the employment agreement, the employee will be entitled to
receive an amount equal to his then current salary for one year. In either case,
payment is due in one lump sum on the effective date of termination. In the
event of a change in control of the Company (as defined in the agreement) during
the Initial Term, if the employee is not given at least five days' notice of
such change in control, the employee may elect to terminate his employment and
receive in one lump sum three times the amount he would receive pursuant to a
termination without cause during the Initial Term. The non-competition
provisions of the employment agreement do not apply to a termination without
such notice. In the event the employee is given at least five days' notice of
such change in control, the employee may elect to terminate his employment
agreement and receive in one lump sum two times the amount he would receive
pursuant to a termination without cause during the Initial Term. In such event,
the non-competition provisions of the employment agreement would apply for two
years from the effective date of termination. Each employment agreement contains
a covenant not to compete with the Company for a period of two years immediately
following termination of employment or, in the case of a termination by the
Company without cause in the absence of a change in control, for a period of one
year following termination of employment.

At least one principal executive officer of each of the other Founding
Companies has entered into an employment agreement, containing substantially the
same provisions, including a covenant not to compete, as Messrs. Nothum's and
Power's employment agreements.

1997 LONG-TERM INCENTIVE PLAN

No stock options were granted to, or exercised by or held by any executive
officer in 1996. In March 1997, the Board of Directors and the Company's
stockholders approved the Company's 1997 Long-Term Incentive Plan (the
"Plan"). The purpose of the Plan is to provide directors, officers, key
employees, consultants and other service providers with additional incentives by
increasing their ownership interests in the Company. Individual awards under the
Plan may take the form of one or more of: (i) either incentive stock options
("ISOs") or non-qualified stock options ("NQSOs"), (ii) stock appreciation
rights ("SARs"), (iii) restricted or deferred stock, (iv) dividend equivalents
and (v) other awards not otherwise provided for, the value of which is based in
whole or in part upon the value of the Common Stock.

The Compensation Committee will administer the Plan and select the
individuals who will receive awards and establish the terms and conditions of
those awards. The maximum number of shares of Common Stock that may be subject
to outstanding awards, determined immediately after the grant of any award, may
not exceed the greater of 2,500,000 shares or 13% of the aggregate number of
shares of Common Stock outstanding. Shares of Common Stock which are
attributable to awards which have expired, terminated or been canceled or
forfeited are available for issuance or use in connection with future awards.

The Plan will remain in effect until terminated by the Board of Directors.
The Plan may be amended by the Board of Directors without the consent of the
stockholders of the Company, except that any amendment, although effective when
made, will be subject to stockholder approval if required by any Federal or
state law or regulation or by the rules of any stock exchange or automated
quotation system on which the Common Stock may then be listed or quoted.

At the closing of the IPO, NQSOs to purchase a total of 675,000 shares of
Common Stock were granted as follows: 200,000 shares to Mr. Ferreira, 100,000
shares to Mr. Beittenmiller, 100,000 shares to Mr. Busbee, 100,000 shares to Mr.
Lemmon, 75,000 shares to Mr. George, 50,000 shares to Mr. Honeycutt and 50,000
shares to Mr. Vensel. In addition, options to purchase 1,583,653 shares have
been granted to certain employees of the Company. Each of the foregoing options
has an exercise price equal to the stock price on the date of grant. These
options will vest at the rate of 20% per year, commencing on the first
anniversary of the date of grant and will expire at the earlier of seven years
from the date of grant or three months following termination of employment.

1997 NON-EMPLOYEE DIRECTORS' STOCK PLAN

The Company's 1997 Non-Employee Directors' Stock Plan (the "Directors'
Plan"), which was adopted by the Board of Directors and approved by the
Company's stockholders in March 1997, provides for (i) the automatic grant to
each non-employee director serving at the consummation of the IPO of an option
to purchase 10,000 shares, (ii) the automatic grant to each non-employee
director of an option to purchase 10,000 shares upon such person's initial
election as a director and (iii) an automatic annual grant to each non-employee
director of an option to purchase 5,000 shares at each annual meeting of
stockholders thereafter at which such director is re-elected or remains a
director, unless such annual meeting is held within three months of such
person's initial election as a director. All options have an exercise price per
share equal to the fair market value of the Common Stock on the date of grant
and are immediately vested and expire on the earlier of ten years from the date
of grant or one year after termination of service as a director. The Directors'
Plan also permits non-employee directors to elect to receive, in lieu of cash
directors' fees, shares or credits representing "deferred shares" at future
settlement dates, as selected by the director. The number of shares or deferred
shares received will equal the number of shares of Common Stock which, at the
date the fees would otherwise be payable, will have an aggregate fair market
value equal to the amount of such fees.

CERTAIN TRANSACTIONS

ORGANIZATION OF THE COMPANY

In connection with the formation of Comfort Systems, Comfort Systems issued
to Notre a total of 2,969,912 shares of Common Stock for an aggregate cash
consideration of $29,699. Mr. Harter is the President of Notre and a director of
the Company. In March 1997, Notre exchanged 2,742,912 shares of Common Stock for
an equal number of shares of Restricted Common Stock. Notre advanced $1.4
million to provide funds necessary to effect the Mergers and the IPO. All of
Notre's advances were repaid from the net proceeds of the IPO.

In January and February 1997, the Company issued a total of 902,435 shares
of Common Stock at $.01 per share to various members of management, as follows:
Mr. Ferreira -- 479,435 shares, Mr. Beittenmiller -- 116,000 shares, Mr.
Busbee -- 116,000 shares, Mr. George -- 75,000 shares, Mr. Honeycutt -- 58,000

shares of Common Stock under the Directors' Plan, effective upon the
consummation of the IPO, to Mr. Harter, a Director of the Company, and to
Messrs. Mercadante and Martin, who became directors of the Company upon the
closing of the IPO.

In connection with the IPO, Comfort Systems acquired by merger or share

of which is now a wholly-owned subsidiary of the Company. The aggregate
consideration paid by Comfort Systems in the Mergers consisted of $45.3 million
in cash and 9,720,927 shares of Common Stock. In addition, prior to the Mergers,
Accurate distributed to Thomas J. Beaty real property having a net book value of
approximately $370,000.

Company for five years, commencing on the date of consummation of the IPO.

LEASES OF REAL PROPERTY BY FOUNDING COMPANIES

Atlas leases its office space in Houston, Texas, as well as mobile homes
located in Austin, Texas; Phoenix, Arizona; and Antioch, Tennessee. These
properties are owned by M & B Interests, Inc. ("M & B"), a corporation
wholly-owned by Mr. Brian S. Atlas, who is a director of the Company, and his
brother, Mr. Michael Atlas. The lease for the real property in Houston expires
on September 30, 1997 and provides for an annual rental of $90,000. The three
single family residences are leased on a month-to-month basis, at an annual
aggregate rental of $36,780. The Company has also agreed with M & B to lease a
recently constructed office and warehouse facility constructed by M & B in
Houston for an annual rental of $204,000. This new office and warehouse facility
replaced Atlas' existing facility. The Company believes that the rent for these
properties does not exceed fair market value.

Tri-City leases its office space in Tempe, Arizona from Mr. Nothum, Jr. and
his father. Mr. Nothum, Jr. is a trustee of a family trust that is a
stockholder of Tri-City and will become a director of the Company upon
consummation of this Offering. The lease expires on June 30, 1998 and provides
for an annual rental of $120,000. Additionally, Tri-City provides liability
insurance on the property and is responsible for any increases in real property
taxes due to its improvement of the leased property. Tri-City has entered into
an agreement with a limited liability corporation owned by Mr. Nothum, Jr. and
his father to lease office, operations and warehouse facilities which are being
constructed, for a ten year term at annual rental of $530,100. The Company
believes that the rent for these properties does not and will not exceed fair
market value.

Lawrence leases its office space and fabrication facility in Jackson,
Tennessee from the father of Mr. Samuel M. Lawrence III, who is Lawrence's Chief
Executive Officer and a director of the Company. The lease expires on October
31, 1997 and provides for an annual rental of $110,400. Additionally, Lawrence
provides liability insurance on the property and pays its proportionate share of
ad valorem taxes, utilities and maintenance costs. The Company believes that the
rent for this property does not exceed fair market value.

52
<PAGE>
Accurate leases two parcels of real property in Houston, Texas owned by Mr.
Beaty, who is a director of the Company. One of the leased premises is used by
Accurate for office and warehouse space. The lease on one of these premises
expires on June 30, 2002 and provides for an annual rental of $38,000. The other
leased premise is used by Accurate as a sheet metal shop under a lease dated
July 1, 1997, that will expire on June 30, 2002 and will provide for an annual
rental of $46,700. The rental rate on these premises in subsequent years of the
lease term will be adjusted in accordance with the Consumer Price Index.
Additionally, Accurate will pay all utility, taxes and insurance costs on both
leased premises. Accurate has options to renew each lease for two additional
five-year terms. The Company believes that the rent for both properties does not
and will not exceed fair market value. Accurate previously owned the property it
uses for its sheet metal shop. Prior to the Mergers, Accurate distributed this
property having a net book value of approximately $370,000 to Mr. Beaty.

Eastern leases its office and warehouse space in Albany, New York from 60
Loudonville Road Associates ("Loudonville"), a partnership of Mr. Alfred J.
Giardenelli, Jr., who is a director of the Company, and his brother. The lease
provides for annual rental of $55,000 and payment by Eastern of taxes,
maintenance, repairs, utilities and insurance costs on the leased premises. The
Company believes that the rent for this property does not exceed the fair market
value. The lease expires on December 31, 1999. Prior to expiration, however,
Eastern intends to enter into a 10-year lease with Loudonville for a new
building and to terminate the existing lease. Eastern has agreed to install the
HVAC systems in the new building at a price which the Company believes to be at
a fair market value. The Company's annual rental in the new building will be at
fair market value, as determined by an appraisal.

CSI/Bonneville leases its office and warehouse space in Salt Lake Valley,
Utah from J & J Investments, a joint venture partly owned by Mr. Phillips, who
is a director of the Company. This lease expires on February 28, 2002 and
provides for an annual rental in 1997 of $120,720, increasing annually by 5%.
CSI/Bonneville is responsible for ad valorem taxes, maintenance, insurance and
third-party management costs related thereto. CSI/Bonneville has options to
renew the lease for two additional five-year terms at a fair market value, as
determined by an appraisal. The Company believes that the rent for this property
does not exceed fair market value.

Tech leases its office and warehouse space in Solon, Ohio from Mr. Cook,
who is a director of the Company. The lease expires on April 2, 2000, and
provides for an annual rental of $84,000. Tech is responsible for its utility
costs, 15% of common utility costs and 50% of the landlord's cost of servicing
and maintaining the premises and providing comprehensive liability insurance for
the leased premises. The Company believes that the rent for such property does
not exceed fair market value.

Quality leases its warehouse facility in Grand Rapids, Michigan from Mr.
Powers, who is a director of the Company. Construction of the warehouse facility
was financed with the proceeds of a public bond issue. The lease expires on
April 30, 2005, and provides for an annual rental of the greater of $216,000 or
Mr. Powers' costs for the leased warehouse, including bond debt service or
mortgage payments, utilities, insurance, ad valorem taxes, maintenance and
repairs. Quality has an option to renew the lease for one additional three-year
term on the same terms. The Company believes that the rent for such property
does not exceed fair market value. Quality has guaranteed the payment of two
series of public bonds issued in 1985 and 1990, respectively, by the Michigan
Strategic Fund on behalf of two real property development entities owned by Mr.
Powers, the proceeds of which were used to fund the construction of Quality's
leased warehouse facility and a second adjacent warehouse. After the IPO, these
bonds were repaid.

The Company has adopted a policy that, whenever possible, it will not own
any real estate. Accordingly, in connection with future acquisitions, the
Company may require the distribution of real property owned by acquired
companies to its stockholders and the leaseback of such property at fair market
value.

DESCRIPTION OF CAPITAL STOCK

GENERAL

The authorized capital stock of the Company consists of 57,969,912 shares
of capital stock, consisting of 50,000,000 shares of Common Stock, 2,969,912
shares of Restricted Common Stock and 5,000,000 shares of Preferred Stock. The
Company has outstanding 23,492,060 shares of Common Stock, which includes
2,742,912 shares of Restricted Common Stock and no shares of Preferred Stock.
The following discussion is qualified in its entirety by reference to the
Restated Certificate of Incorporation of Comfort Systems, which is included as
an exhibit to the Registration Statement of which this Prospectus is a part.

COMMON STOCK AND RESTRICTED COMMON STOCK

The holders of Common Stock are each entitled to one vote for each share
held on all matters to which they are entitled to vote, including the election
of directors. The holders of Restricted Common Stock, voting together as a
single class, are entitled to elect one member of the Company's Board of
Directors and to 0.55 of one vote for each share held on all other matters on
which they are entitled to vote. Holders of Restricted Common Stock are not
entitled to vote on the election of any other directors. Upon consummation of
this Offering, the Board of Directors will be classified into three classes as
nearly equal in number as possible, with the term of each class expiring on a
staggered basis. The classification of the Board of Directors may make it more
difficult to change the composition of the Board of Directors and thereby may
discourage or make more difficult an attempt by a person or group to obtain
control of the Company. Cumulative voting for the election of directors is not
permitted. Any director, or the entire Board of Directors, may be removed at any
time, with cause, by of a majority of the aggregate number of votes which may be
cast by the holders of all of the outstanding shares of Common Stock and
Restricted Common Stock entitled to vote for the election of directors, except
that only the holder of the Restricted Common Stock may remove the director such
holder is entitled to elect.

Subject to the rights of any then outstanding shares of Preferred Stock,
holders of Common Stock and Restricted Common Stock are together entitled to
participate pro rata in such dividends as may be declared in the discretion of
the Board of Directors out of funds legally available therefor. Holders of
Common Stock and Restricted Common Stock together are entitled to share ratably
in the net assets of the Company upon liquidation after payment or provision for
all liabilities and any preferential liquidation rights of any Preferred Stock
then outstanding. Holders of Common Stock and holders of Restricted Common Stock
have no preemptive rights to purchase shares of stock of the Company. Shares of
Common Stock are not subject to any redemption provisions and are not
convertible into any other securities of the Company. Shares of Restricted
Common Stock are not subject to any redemption provisions and are convertible
into Common Stock as described below. All outstanding shares of Common Stock and
Restricted Common Stock are, and the shares of Common Stock to be issued
pursuant to this Offering will be, upon payment therefor, fully paid and
non-assessable.

Each share of Restricted Common Stock will automatically convert to Common
Stock on a share-for-share basis (i) in the event of a disposition of such share
of Restricted Common Stock by the holder thereof (other than a distribution by a
holder to its partners or beneficial owners, or a transfer to a related party of
such holders (as defined in Sections 267, 707, 318 and/or 4946 of the Internal
Revenue Code of 1986, as amended)), (ii) in the event any person acquires
beneficial ownership of 15% or more of the total number of outstanding shares of
Common Stock, or (iii) in the event any person offers to acquire 15% or more of
the total number of outstanding shares of Common Stock. After July 1, 1998, the
Board of Directors may elect to convert any remaining shares of Restricted
Common Stock into shares of Common Stock in the event 80% or more of the
originally outstanding shares of Restricted Common Stock have been previously
converted into shares of Common Stock.

The Common Stock is listed on The New York Stock Exchange under the symbol
"FIX." The Restricted Common Stock is not listed on any exchange.

56
<PAGE>
PREFERRED STOCK

The Preferred Stock may be issued from time to time by the Board of
Directors in one or more series. Subject to the provisions of the Company's
Certificate of Incorporation and limitations prescribed by law, the Board of
Directors is expressly authorized to adopt resolutions to issue the shares, to
fix the number of shares and to change the number of shares constituting any
series and to provide for or change the voting powers, designations, preferences
and relative, participating, optional or other special rights, qualifications,
limitations or restrictions thereof, including dividend rights (including
whether dividends are cumulative), dividend rates, terms of redemption
(including sinking fund provisions), redemption prices, conversion rights and
liquidation preferences of the shares constituting any series of the Preferred
Stock, in each case without any further action or vote by the stockholders. The
Company has no current plans to issue any shares of Preferred Stock.

One of the effects of undesignated Preferred Stock may be to enable the
Board of Directors to render more difficult or to discourage an attempt to
obtain control of the Company by means of a tender offer, proxy contest, merger
or otherwise, and thereby to protect the continuity of the Company's management.
The issuance of shares of the Preferred Stock pursuant to the Board of
Directors' authority described above may adversely affect the rights of the
holders of Common Stock. For example, Preferred Stock issued by the Company may
rank prior to the Common Stock and Restricted Common Stock as to dividend
rights, liquidation preference or both, may have full or limited voting rights
and may be convertible into shares of Common Stock. Accordingly, the issuance of
shares of Preferred Stock may discourage bids for the Common Stock or may
otherwise adversely affect the market price of the Common Stock.

STATUTORY BUSINESS COMBINATION PROVISION

The Company is subject to Section 203 of the DGCL which, with certain
exceptions, prohibits a Delaware corporation from engaging in any of a broad
range of business combinations with any "interested stockholder" for a period
of three years following the date that such stockholder became an interested
stockholder, unless: (i) prior to such date, the Board of Directors of the
corporation approved either the business combination or the transaction which
resulted in the stockholder becoming an interested stockholder, (ii) upon
consummation of the transaction which resulted in the stockholder becoming an
interested stockholder, the interested stockholder owned at least 85% of the
voting stock of the corporation outstanding at the time the transaction
commenced, excluding for purposes of determining the number of shares
outstanding those shares owned (a) by persons who are directors and officers and
(b) by employee stock plans in which employee participants do not have the right
to determine confidentially whether shares held subject to the plan will be
tendered in a tender or exchange offer, or (iii) on or after such date, the
business combination is approved by the Board of Directors and authorized at an
annual or special meeting of stockholders by the affirmative vote of at least
66 2/3% of the outstanding voting stock which is not owned by the interested
stockholder. An "interested stockholder" is defined as any person that is (a)
the owner of 15% or more of the outstanding voting stock of the corporation or
(b) an affiliate or associate of the corporation and was the owner of 15% or
more of the outstanding voting stock of the corporation at any time within the
three-year period immediately prior to the date on which it is sought to be
determined whether such person is an interested stockholder.

CERTAIN PROVISIONS OF THE CERTIFICATE OF INCORPORATION AND BYLAWS

Pursuant to the Company's Certificate of Incorporation and as permitted by
Delaware law, directors of the Company are not liable to the Company or its
stockholders for monetary damages for breach of fiduciary duty, except for
liability in connection with a breach of duty of loyalty, for acts or omissions
not in good faith or which involve intentional misconduct or a knowing violation
of law, for dividend payments or stock repurchases illegal under Delaware law or
any transaction in which a director has derived an improper personal benefit.

Additionally, the Certificate of Incorporation of the Company provides that
directors and officers of the Company shall be, and at the discretion of the
Board of Directors non-officer employees and agents may be, indemnified by the
Company to the fullest extent authorized by Delaware law, as it now exists or
may in

57
<PAGE>
the future be amended, against all expenses and liabilities actually and
reasonably incurred in connection with service for or on behalf of the Company,
and further permits the advancing of expenses incurred in defense of claims.

The Certificate of Incorporation also provides that any action required or
permitted to be taken by the stockholders of the Company at an annual or special
meeting of stockholders must be effected at a duly called meeting and may not be
taken or effected by a written consent of stockholders in lieu thereof. The
Company's Bylaws provide that a special meeting of stockholders may be called
only by the Chief Executive Officer, by a majority of the Board of Directors, or
by a majority of the Executive Committee of the Board of Directors. The Bylaws
provide that only those matters set forth in the notice of the special meeting
may be considered or acted upon at that special meeting. To amend or repeal the
Company's Bylaws, an amendment or repeal thereof must first be approved by the
Board of Directors or by affirmative vote of the holders of at least 66 2/3% of
the total votes eligible to be cast by holders of voting stock with respect to
such amendment or repeal.

The Company's Bylaws establish an advance notice procedure with regard to
the nomination, other than by or at the direction of the Board of Directors or a
committee thereof, of candidates for election as directors (the "Nomination
Procedure") and with regard to other matters to be brought by stockholders
before an annual meeting of stockholders of the Company (the "Business
Procedure"). The Nomination Procedure requires that a stockholder give prior
written notice, in proper form, of a planned nomination for the Board of
Directors to the Secretary of the Company. The requirements as to the form and
timing of that notice are specified in the Company's Bylaws. If the Chairman of
the Board of Directors determines that a person was not nominated in accordance
with the Nomination Procedure, such person will not be eligible for election as
a director. Under the Business Procedure, a stockholder seeking to have any
business conducted at an annual meeting must give prior written notice, in
proper form, to the Secretary of the Company. The requirements as to the form
and timing of that notice are specified in the Company's Bylaws. If the Chairman
of the Board of Directors determines that the other business was not properly
brought before such meeting in accordance with the Business Procedure, such
business will not be conducted at such meeting.

Although the Company's Bylaws do not give the Board of Directors any power
to approve or disapprove stockholder nominations for the election of directors
or of any other business desired by stockholders to be conducted at an annual or
any other meeting, the Company's Bylaws (i) may have the effect of precluding a
nomination for the election of directors or precluding the conduct of business
at a particular meeting if the proper procedures are not followed or (ii) may
discourage or deter a third party from conducting a solicitation of proxies to
elect its own slate of directors or otherwise attempting to obtain control of
the Company, even if the conduct of such solicitation or such attempt might be
beneficial to the Company and its stockholders.

TRANSFER AGENT AND REGISTRAR

The Transfer Agent and Registrar for the Common Stock is American Stock
Transfer & Trust Company, 40 Wall Street, New York, New York, 10005.

<PAGE>
SHARES ELIGIBLE FOR FUTURE SALE

The Company has outstanding 23,492,060 shares of Common Stock. The
7,015,000 shares sold in the IPO, 34,496 shares issued in acquisitions and
583,878 shares registered hereunder will be freely tradeable without restriction
unless acquired by affiliates of the Company. The remaining outstanding shares
of Common Stock or Restricted Common Stock either have not been registered under
the Securities Act, which means that they may be resold publicly only upon
registration under the Securities Act or in compliance with an exemption from
the registration requirements of the Securities Act, including the exemption
provided by Rule 144 thereunder, or are otherwise subject to contractual
restrictions on transfer.

In general, under Rule 144, if a period of at least one year has elapsed
between the later of the date on which restricted securities were acquired from
the Company or the date on which they were acquired from an affiliate, the
holder of such restricted securities (including an affiliate) is entitled to
sell a number of shares within any three-month period that does not exceed the
greater of (i) one percent of the then outstanding shares of the Common Stock or
(ii) the average weekly reported volume of trading of the Common Stock during
the four calendar weeks preceding such sale. Sales under Rule 144 are also
subject to certain requirements pertaining to the manner of such sales, notices
of such sales and the availability of current public information concerning the
Company. Affiliates may sell shares not constituting restricted securities in
accordance with the foregoing volume limitations and other requirements but
without regard to the one year holding period. Under Rule 144(k), if a period of
at least two years has elapsed between the later of the date on which restricted
securities were acquired from the Company and the date on which they were
acquired from an affiliate, a holder of such restricted securities who is not an
affiliate at the time of the sale and has not been an affiliate for a least
three months prior to the sale is entitled to sell the shares immediately
without regard to the volume limitations and other conditions described above.

The Company and its officers, directors and certain stockholders, who
beneficially own 4,239,947 shares in the aggregate, have agreed not to sell or
otherwise dispose of any shares of Common Stock or Restricted Common Stock for a
period of 180 days after the date of this Prospectus without the prior written
consent of Alex. Brown & Sons Incorporated, except that the Company may issue
Common Stock in connection with acquisitions, in connection with its 1997
Long-Term Incentive Plan and its 1997 Non-Employee Directors' Stock Plan (the
"Plans") or upon conversion of shares of the Restricted Common Stock. See
"Underwriting." In addition, all of the stockholders of the Founding
Companies, the Company's officers and directors and certain stockholders,
holding in the aggregate 13,960,874 shares of Common Stock, have agreed with the
Company that they will not sell any of their shares for a period of one year
after the closing of the IPO. These stockholders, however, have the right, in
the event the Company proposes to register under the Securities Act any Common
Stock for its own account or for the account of others, subject to certain
exceptions, to require the Company to include their shares in the registration,
subject to the right of the Company to exclude some or all of the shares in the
offering upon the advice of the managing underwriter. In addition, certain of
such stockholders have certain limited demand registration rights to require the
Company to register shares held by them following the first anniversary of the
closing of the IPO. In addition, 1,550,424 shares issued in acquisitions since
the IPO will become tradeable on the first anniversaries of such acquisitions
late in the third quarter and early in the fourth quarter of 1998, 252,292 of
such shares will become tradeable during the same period in 1999, 68,879 of such
shares will become tradeable during the same period in 2000, and 25,317 of such
shares will become tradeable during the same period in 2001.

The Company registered 8,000,000 shares of its Common Stock under the
Securities Act for use by the Company in connection with future acquisitions.
After the effective date of such registration, any such shares that may be
issued will generally be freely tradeable, unless acquired by persons who become
affiliates of the Company. In some instances, however, the Company may
contractually restrict the sale of shares issued in connection with future
acquisitions. As of October 31, 1997, 7,682,333 shares remained available for
use in future acquisitions under such shelf. The piggyback registration rights
described above do not apply to the registration statement relating to these
8,000,000 shares or to this registration statement.

No prediction can be made as to the effect, if any, that the sale of shares
or the availability of shares for sale will have on the market price for the
Common Stock prevailing from time to time. Nevertheless, sales, or the
availability for sale of, substantial amounts of the Common Stock in the public
market could adversely affect prevailing market prices and the future ability of
the Company to raise equity capital and complete any additional acquisitions for
Common Stock.

COMFORT SYSTEMS USA, INC. AND FOUNDING COMPANIES
UNAUDITED PRO FORMA COMBINED FINANCIAL STATEMENTS
BASIS OF PRESENTATION

The following unaudited pro forma combined financial statements give effect
to the acquisitions by Comfort Systems USA, Inc. ("Comfort Systems") of the
outstanding capital stock of Quality, Atlas, Tri-City, Lawrence, Accurate,
Eastern, CSI/Bonneville, Seasonair, Tech, Western, Freeway and Standard
(together, the "Founding Companies"). These acquisitions (the "Mergers")
occurred concurrently with the closing of Comfort Systems' initial public
offering (the "IPO") and were accounted for using the purchase method of
accounting. Comfort Systems has been identified as the accounting acquirer for
financial statement presentation purposes.

The unaudited pro forma combined balance sheet gives effect to the Mergers
and the IPO as if they had occurred on June 30, 1997. The unaudited pro forma
combined statements of operations give effect to these transactions as if they
had occurred on January 1, 1996.

Comfort Systems has preliminarily analyzed the savings that it expects to
be realized from reductions in salaries and certain benefits to the owners. To
the extent the owners of the Founding Companies have agreed prospectively to
reductions in salary, bonuses and benefits, these reductions have been reflected
in the pro forma combined statements of operations. With respect to other
potential cost savings, Comfort Systems has not and cannot quantify these
savings until completion of the combination of the Founding Companies. It is
anticipated that these savings will be offset by costs related to Comfort
Systems' new corporate management and by the costs associated with being a
public company. However, because these costs cannot be accurately quantified at
this time, they have not been included in the pro forma financial information of
Comfort Systems.

The pro forma adjustments are based on estimates, available information and
certain assumptions and may be revised as additional information becomes
available. The pro forma financial data do not purport to represent what Comfort
Systems' financial position or results of operations would actually have been if
such transactions in fact had occurred on those dates and are not necessarily
representative of the Comfort Systems' financial position or results of
operations for any future period. Since the Founding Companies were not under
common control or management, historical combined results may not be comparable
to, or indicative of, future performance. The unaudited pro forma combined
financial statements should be read in conjunction with the other financial
statements and notes thereto included elsewhere in this Prospectus. See "Risk
Factors" included elsewhere herein.

COMFORT SYSTEMS USA, INC. AND FOUNDING COMPANIES
NOTES TO UNAUDITED PRO FORMA COMBINED FINANCIAL STATEMENTS

1. GENERAL:

Comfort Systems USA, Inc. ("Comfort Systems") was founded to become a
leading national provider of comprehensive heating, ventilation and air
conditioning ("HVAC") installation services as well as maintenance, repair and
replacement of HVAC systems, focusing primarily on commercial and industrial
markets. Comfort Systems conducted no operations prior to the IPO and acquired
the Founding Companies concurrently with and as a condition to the closing of
the Offering.

The historical financial statements reflect the financial position and
results of operations of the Founding Companies and were derived from the
respective Founding Companies' financial statements where indicated. The periods
included in these financial statements for the individual Founding Companies are
as of and for the six months ended June 30, 1997 and for the year ended December
31, 1996, with the exception of Lawrence for which the period is as of and for
the fiscal year ended October 31, 1996. The audited historical financial
statements included elsewhere herein have been included in accordance with
Securities and Exchange Commission ("SEC") Staff Accounting Bulletin No. 80.

2. ACQUISITION OF FOUNDING COMPANIES:

Concurrently with and as a condition to the closing of the IPO, Comfort
Systems acquired all of the outstanding capital stock of the Founding Companies.
The acquisitions were accounted for using the purchase method of accounting with
Comfort Systems being treated as the accounting acquirer.

The following table sets forth the consideration paid (a) in cash and (b)
in shares of Common Stock to the common stockholders of each of the Founding
Companies. For purposes of computing the estimated purchase price for accounting
purposes, the value of the shares was determined using an estimated fair value
of $10.40 per share (or $101.1 million), which represents a discount of twenty
percent from the initial public offering price of $13.00 due to restrictions on
the sale and transferability of the shares issued. The total estimated purchase
price of $146.4 million for the acquisitions is based upon preliminary estimates
and is subject to certain purchase price adjustments at and following closing.
The table does not reflect the distributions totaling $20.9 million as of June
30, 1997 constituting substantially all of the Founding Companies undistributed
earnings previously taxed to their stockholders ("S Corporation
Distributions").

NOTES TO FINANCIAL STATEMENTS

1. BUSINESS AND ORGANIZATION:

Comfort Systems USA, Inc., a Delaware corporation, ("Comfort Systems" or
the "Company") was founded in December 1996 to become a national provider of
comprehensive HVAC installation services and maintenance, repair and replacement
of HVAC systems, focusing primarily on the commercial and industrial markets.
Comfort intends to acquire 12 U.S. businesses (the "Mergers"), complete an
initial public offering (the "Offering") of its common stock and, subsequent
to the Offering, continue to acquire through merger or purchase, similar
companies to expand its national operations.

Comfort Systems has not conducted any operations, and all activities to
date have related to the Offering and the Mergers. The Company's cash balances
were generated from the initial capitalization of the Company (see Note 3). All
other expenditures to date have been funded by the primary stockholder, Notre
Capital Ventures II, L.L.C. ("Notre"), on behalf of the Company. Since there
were no revenues, expenses or cash flows from Inception (December 12, 1996)
through December 31, 1996, statements of operations and cash flows have been
omitted for this period. Notre has committed to fund the organization expenses
and offering costs. As of December 31, 1996 and June 30, 1997, costs of
approximately $177,000 and $4,936,000 (unaudited), respectively have been
incurred by Notre in connection with the Offering. Comfort Systems has treated
these costs as deferred offering costs.

2. INTERIM FINANCIAL INFORMATION:

The interim financial statements as of June 30, 1997, and for the six
months then ended are unaudited, and certain information and footnote
disclosures, normally included in financial statements prepared in accordance
with generally accepted accounting principles, have been omitted. In the opinion
of management, all adjustments, consisting only of normal recurring adjustments,
necessary to fairly present the financial position, results of operations and
cash flows with respect to the interim financial statements, have been included.
The results of operations for the interim period is not necessarily indicative
of the results for the entire fiscal year.

3. STOCKHOLDER'S EQUITY:

COMMON STOCK AND PREFERRED STOCK

Comfort Systems effected a 121.1387-for-one stock split on March 19, 1997
for each share of common stock of the Company ("Common Stock") then
outstanding. In addition, the Company increased the number of authorized shares
of Common Stock to 52,969,912 and authorized 5,000,000 shares of $.01 par value
preferred stock. The effects of the Common Stock split and the increase in the
shares of authorized Common Stock have been retroactively reflected on the
balance sheet and in the accompanying notes.

In connection with the organization and initial capitalization of Comfort
Systems, the Company issued 121,139 shares of common stock at $.01 per share to
Notre. In January 1997, the Company issued 2,848,773 additional shares to Notre
for $.01 per share.

In January and February 1997, the Company issued a total of 1,269,935
shares of Common Stock to management and consultants to the Company at a price
of $.01 per share. As a result, the Company recorded a non-recurring, non-cash
compensation charge of $11.6 million (unaudited) in the first quarter of 1997,
representing the difference between the amount paid for the shares and an
estimated fair value of the shares on the date of sale.

RESTRICTED COMMON STOCK

In March 1997, the primary stockholder exchanged its 2,742,912 shares of
Common Stock for an equal number of shares of restricted voting common stock
("Restricted Common Stock"). The holder of Restricted Common Stock is entitled
to elect one member of the Company's Board of Directors and to 0.55

F-16
<PAGE>
COMFORT SYSTEMS USA, INC.
NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)

of one vote for each share on all other matters on which they are entitled to
vote. Holders of Restricted Common Stock are not entitled to vote on the
election of any other directors.

Each share of Restricted Common Stock will automatically convert to Common
Stock on a share-for-share basis (i) in the event of a disposition of such share
of Restricted Common Stock by the holder thereof (other than a distribution
which is a distribution by a holder to its partners or beneficial owners, or a
transfer to a related party of such holders (as defined in Sections 267, 707,
318 and/or 4946 of the Internal Revenue of 1986, as amended)), (ii) in the event
any person acquires beneficial ownership of 15% or more of the total number of
outstanding shares of Common Stock of the Company, or (iii) in the event any
person offers to acquire 15% or more of the total number of outstanding shares
of Common Stock of the Company. After July 1, 1998, the Board of Directors may
elect to convert any remaining shares of Restricted Common Stock into shares of
Common Stock in the event 80% or more of the originally outstanding shares of
Restricted Common Stock have been previously converted into shares of Common
Stock.

LONG-TERM INCENTIVE PLAN

In March 1997, the Company's stockholders approved the Company's 1997
Long-Term Incentive Plan (the "Plan"), which provides for the granting or
awarding of incentive or non-qualified stock options, stock appreciation rights,
restricted or deferred stock, dividend equivalents and other incentive awards to
directors, officers, key employees and consultants to the Company. The number of
shares authorized and reserved for issuance under the Plan is the greater of
2,500,000 shares or 13% of the aggregate number of shares of Common Stock
outstanding. The terms of the option awards will be established by the
Compensation Committee of the Company's Board of Directors. The Company intends
to file a registration statement on Form S-8 under the Securities Act
registering the issuance of shares upon exercise of options granted under this
Plan. The Company expects to grant non-qualified stock options to purchase a
total of 675,000 shares of Common Stock to key employees of the Company at the
initial public offering price upon consummation of the Offering. In addition,
the Company expects to grant options to purchase a total of 1,271,953 shares of
Common Stock to certain employees of the Founding Companies at the initial
public offering price per share. These options will vest at the rate of 20% per
year, commencing on the first anniversary of the IPO and will expire seven years
from the date of grant or three months following termination of employment.

NON-EMPLOYEE DIRECTORS STOCK PLAN

In March 1997, the Company's stockholders approved the 1997 Non-Employee
Directors' Stock Plan (the "Directors' Plan"), which provides for the granting
or awarding of stock options and stock appreciation rights to nonemployees. The
number of shares authorized and reserved for issuance under the Stock Plan is
250,000 shares. The Directors' Plan provides for the automatic grant of options
to purchase 10,000 shares to each non-employee director serving at the
commencement of the Offering.

Each non-employee director will be granted options to purchase an
additional 10,000 shares at the time of the initial election. In addition, each
director will be automatically granted options to purchase 5,000 shares at each
annual meeting of the stockholders occurring more than two months after the date
of the director's initial election. All options will be exercised at the fair
market value at the date of grant and are immediately vested upon grant.

Options will be granted to each of two future and one current member of the
board of directors to purchase 10,000 shares of Common Stock at the initial
Offering price per share effective upon the consummation of this Offering. These
options will expire the earlier of 10 years from the date of grant or one year
after termination of service as a director.

F-17
<PAGE>
COMFORT SYSTEMS USA, INC.
NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)

The Directors' Plan allows non-employee directors to receive shares
("deferred shares") at future settlement dates in lieu of cash. The number of
deferred shares will have an aggregate fair market value equal to the fees
payable to the directors.

4. STOCK BASED COMPENSATION:

Statement of Financial Accounting Standards ("SFAS") No. 123,
"Accounting for Stock-Based Compensation," allows entities to choose between a
new fair value based method of accounting for employee stock options or similar
equity instruments and the current intrinsic, value-based method of accounting
prescribed by Accounting Principles Board Opinion No. 25 ("APB No. 25").
Entities electing to remain with the accounting in APB Opinion No. 25 must make
pro forma disclosures of net income and earnings per share as if the fair value
method of accounting had been applied. The Company will provide pro forma
disclosure of net income and earnings per share, as applicable, in the notes to
future consolidated financial statements.

5. EVENTS SUBSEQUENT TO THE DATE OF AUDITORS' REPORT OF INDEPENDENT PUBLIC
ACCOUNTANTS (UNAUDITED):

Wholly-owned subsidiaries of Comfort Systems have acquired by merger or
share exchange 12 companies ("Founding Companies"). The companies are Accurate
Air Systems, Inc., Atlas Comfort Services USA, Inc. and Subsidiary, Contract
Service, Inc., Eastern Heating and Cooling, Inc., Freeway Heating and Air
Conditioning, Inc., Quality Air Heating & Cooling, Inc., Seasonair, Inc., S.M.
Lawrence Inc. and Related Company, Standard Heating and Air Conditioning
Company, Tech Heating and Air Conditioning, Inc. and Related Company, Tri-City
Mechanical, Inc. and Western Building Services, Inc. The aggregate consideration
paid by Comfort Systems to acquire the Founding Companies was approximately
$45.3 million in cash and 9,720,927 shares of Common Stock.

On June 27, 1997, Comfort Systems completed the Offering, which involved
the sale by Comfort Systems of 6,100,000 shares of Common Stock at a price to
the public of $13.00 per share. The net proceeds to Comfort Systems from the
Offering (after deducting underwriting discounts and commissions and offering
expenses) were approximately $69.7 million. Of this amount, $45.3 million was
used to pay the cash portion of the purchase prices relating to the acquisitions
for the Founding Companies. On July 9, 1997, Comfort Systems sold an additional
915,000 shares of Common Stock at $13.00 per share (which represents net
proceeds to the Company of $11.1 million after underwriting discounts and
commissions) pursuant to an overallotment option granted by Comfort Systems to
the underwriters in connection with the Offering. See "Risk Factors" included
elsewhere herein.

The Company has obtained a revolving line of credit of $75.0 million. The
facility is intended to be used for acquisitions, capital expenditures,
refinancing of debt not paid out of the proceeds of the Offering and for general
corporate purposes. The credit facility requires the Company to comply with
various loan covenants including (i) maintenance of certain financial ratios,
(ii) restrictions on additional indebtedness, and (iii) restrictions on liens,
guarantees, advances and dividends. The line of credit is subject to customary
drawing conditions. As of October 13, 1997, borrowings under the line of credit
were $18.9 million which was used to repay existing indebtedness of the Founding
Companies.

The Company also has outstanding options to purchase up to a total of
2,258,653 shares of Common Stock. Each of these options has an exercise price
equal to the stock price on the date of grant and will vest at the rate of 20%
per year, commencing on the first anniversary of the date of grant and will
expire at the earlier of seven years from the date of grant or three months
following termination of employment.

Since the IPO, and through October 13, 1997, the Company has acquired
eleven additional mechanical contracting companies engaged principally in the
HVAC business. The Company paid approximately $1.6 million in cash and 2,250,449
shares of Common Stock. The Company will account for seven of these acquisitions
as pooling-of-interests transactions and the remaining four acquisitions will be
accounted for as purchase transactions. Annualized revenues for these
acquisitions were approximately $70 million.

QUALITY AIR HEATING & COOLING, INC.
NOTES TO FINANCIAL STATEMENTS

1. BUSINESS AND ORGANIZATION:

Quality Air Heating & Cooling, Inc., a Michigan corporation, (the
"Company") focuses on providing "design and build" installation services and
maintenance, repair and replacement of HVAC systems primarily for mid-sized to
large commercial facilities. Quality primarily operates throughout western
Michigan.

The Company and its shareholders intend to enter into a definitive
agreement with Comfort Systems USA, Inc. ("Comfort Systems"), pursuant to
which all outstanding shares of the Company's common stock will be exchanged for
cash and shares of Comfort Systems common stock concurrently with the
consummation of the initial public offering (the "Offering") of the common
stock of Comfort Systems.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

INTERIM FINANCIAL INFORMATION

The interim financial statements as of June 30, 1997, and for the six
months ended June 30, 1996 and 1997, are unaudited, and certain information and
footnote disclosures, normally included in financial statements prepared in
accordance with generally accepted accounting principles, have been omitted. In
the opinion of management, all adjustments, consisting only of normal recurring
adjustments, necessary to fairly present the financial position, results of
operations and cash flows with respect to the interim financial statements, have
been included. The results of operations for the interim periods are not
necessarily indicative of the results for the entire fiscal year.

CASH AND CASH EQUIVALENTS

The Company considers all highly liquid investments purchased with an
original maturity of three months or less to be cash equivalents.

INVENTORIES

Inventories consist of parts and supplies held for use in the ordinary
course of business and are stated at the lower of cost or market using the
first-in, first-out (FIFO) method.

PROPERTY AND EQUIPMENT

Property and equipment are stated at cost, and depreciation is computed
using the straight-line method over the estimated useful lives of the assets.
Leasehold improvements are capitalized and amortized over the lesser of the life
of the lease or the estimated useful life of the asset.

Expenditures for repairs and maintenance are charged to expense when
incurred. Expenditures for major renewals and betterments, which extend the
useful lives of existing equipment, are capitalized and depreciated. Upon
retirement or disposition of property and equipment, the cost and related
accumulated depreciation are removed from the accounts and any resulting gain or
loss is recognized in the statement of operations.

REVENUE RECOGNITION

The Company recognizes revenue when services are performed except when work
is being performed under a construction contract. Revenues from construction
contracts are recognized on the percentage-of-completion method measured by the
percentage of costs incurred to total estimated costs for each contract.
Provisions for the total estimated losses on uncompleted contracts are made in
the period in which such losses are determined. Changes in job performance, job
conditions, estimated profitability and final contract settlements may result in
revisions to costs and income and their effects are recognized in the period in
which the revisions are determined.

F-24
<PAGE>
QUALITY AIR HEATING & COOLING, INC.
NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)

The balances billed but not paid by customers pursuant to retainage
provisions in construction contracts will be due upon completion of the
contracts and acceptance by the customer. Based on the Company's experience with
similar contracts in recent years, the retention balance will be billed and
collected in the upcoming fiscal year.

WARRANTY COSTS

The Company warrants labor for the first year after installation on new air
conditioning and heating systems. The Company generally warrants labor for 30
days after servicing of existing air conditioning and heating systems. A reserve
for warranty costs is recorded upon completion of installation or service.

INCOME TAXES

The Company has elected S Corporation status as defined by the Internal
Revenue Code, whereby the Company is not subject to taxation for federal
purposes. Under S Corporation status, the shareholders report their share of the
Company's taxable earnings or losses in their personal tax returns. The Company
will terminate its S Corporation status concurrently with the effective date of
this Offering. Included in current assets are deposits to prepay certain of the
shareholders' federal income taxes.

USE OF ESTIMATES

The preparation of financial statements in conformity with generally
accepted accounting principles requires the use of estimates and assumptions by
management in determining the reported amounts of assets and liabilities and
disclosures of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.

NEW ACCOUNTING PRONOUNCEMENT

Effective January 1, 1996, the Company adopted Statement of Financial
Accounting Standards (SFAS) No. 121, "Accounting for the Impairment of
Long-Lived Assets and for Long-Lived Assets to Be Disposed Of." Accordingly, in
the event that facts and circumstances indicate that property and equipment or
other assets may be impaired, an evaluation of recoverability would be
performed. If an evaluation is required, the estimated future undiscounted cash
flows associated with the asset are compared to the asset's carrying amount to
determine if a write-down to market value is necessary. Adoption of this
standard did not have a material effect on the financial position or results of
operations of the Company.

3. PROPERTY AND EQUIPMENT:

Property and equipment consist of the following (dollars in thousands):

We have audited the accompanying consolidated balance sheets of Atlas
Comfort Services USA, Inc. (a Texas corporation) and its subsidiary (the

consolidated statements of operations, shareholders' equity and cash flows for
the years ended June 30, 1994, 1995 and 1996 and the six months ended December
31, 1996. These consolidated financial statements are the responsibility of the
Company's management. Our responsibility is to express an opinion on these
consolidated financial statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the consolidated financial statements are
free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the consolidated financial
statements. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the consolidated financial position of
Atlas Comfort Services USA, Inc., and its subsidiary as of June 30, 1995 and
1996, and December 31, 1996, and the consolidated results of their operations

ATLAS COMFORT SERVICES USA, INC. AND SUBSIDIARY
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. BUSINESS AND ORGANIZATION:

Atlas Comfort Services USA, Inc., a Texas corporation, and its subsidiary
(the "Company") is a leading provider of HVAC installation services for
apartment complexes, condominiums and hotels in the United States and also
provides maintenance, repair and replacement of HVAC systems. Atlas primarily
operates in the southwest, northeast, and the mid-Atlantic regions of the United
States.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

BASIS OF PRESENTATION

The consolidated financial statements include the accounts and results of
operations of the Company and its subsidiary which are under common control and
management of two individuals. All significant intercompany transactions and
balances have been eliminated in combination.

INTERIM FINANCIAL INFORMATION

The interim consolidated financial statements as of June 30, 1997, and for
the six months ended June 30, 1996 and 1997, are unaudited, and certain
information and footnote disclosures, normally included in financial statements
prepared in accordance with generally accepted accounting principles, have been
omitted. In the opinion of management, all adjustments, consisting only of
normal recurring adjustments, necessary to fairly present the financial
position, results of operations and cash flows with respect to the consolidated
interim financial statements, have been included. The results of operations for
the interim periods are not necessarily indicative of the results for the entire
fiscal year.

CASH AND CASH EQUIVALENTS

The Company considers all highly liquid investments purchased with an
original maturity of three months or less to be cash equivalents.

INVENTORIES

Inventories consist of duct materials, air conditioning equipment,
refrigeration supplies and accessories held for use in the ordinary course of
business and are stated at the lower of cost or market using the first-in,
first-out (FIFO) method.

PROPERTY AND EQUIPMENT

F-34
<PAGE>
ATLAS COMFORT SERVICES USA, INC. AND SUBSIDIARY
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

REVENUE RECOGNITION

The Company recognizes revenue when services are performed except when work
is being performed under a construction contract. Revenues from construction
contracts are recognized on the percentage-of-completion method measured by the
percentage of costs incurred to total estimated costs for each contract.
Provisions for the total estimated losses on uncompleted contracts are made in
the period in which such losses are determined. Changes in job performance, job
conditions, estimated profitability and final contract settlements may result in
revisions to costs and income and are recognized in the period in which the
revisions are determined.

WARRANTY COSTS

The Company warrants labor for the first year after installation on new air
conditioning and heating units. The Company generally warrants labor for 30 days
after servicing of existing air conditioning and heating units. A reserve for
warranty costs is recorded upon completion of installation or service.

INCOME TAXES

The Company follows the liability method of accounting for income taxes in
accordance with Statement of Financial Accounting Standards (SFAS) No. 109.
Under this method, deferred income taxes are recorded based upon the differences
between the financial reporting and tax bases of assets and liabilities and are
measured using the enacted tax rates and laws that will be in effect when the
underlying assets or liabilities are recovered or settled.

USE OF ESTIMATES

GOODWILL

Goodwill, in the amount of $33,000, represents the excess of cost over the
fair value of net assets acquired and is amortized using the straight-line
method over 40 years. The Company assesses the recoverability of its goodwill
whenever adverse events occur and believes that no material impairment exists.

NEW ACCOUNTING PRONOUNCEMENTS

Effective July 1, 1996, the Company adopted SFAS No. 121, "Accounting for
the Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed
Of." Accordingly, in the event that facts and circumstances indicate that
property and equipment, and intangible or other assets may be impaired, an
evaluation of recoverability would be performed. If an evaluation is required,
the estimated future undiscounted cash flows associated with the asset are
compared to the asset's carrying amount to determine if a write-down to market
value is necessary. Adoption of this standard did not have a material effect on
the financial position or results of operations of the Company.

9. COMMITMENTS AND CONTINGENCIES:

LITIGATION

The Company is involved in legal actions arising in the ordinary course of
business. Management does not believe the outcome of such legal action will have
a material adverse effect on the Company's financial position or consolidated
results of operations.

INSURANCE

The Company carries a broad range of insurance coverage, including general
and business auto liability, commercial property, workers' compensation and a
general umbrella policy. The Company has not incurred significant claims or
losses on any of its insurance policies.

10. EMPLOYEE BENEFIT PLAN

The Company sponsors a Profit Sharing and Savings Plan (the "Plan") which
covers substantially all employees. The employees who participate in the Plan
may contribute 1 percent to 20 percent of their base compensation, and the
Company may make discretionary matching contributions. The Company did not make
any contributions for the years ended December 31, 1994 and 1995. The Company
made $18,248 in contributions for the year ended June 30, 1996 and $12,667 for
the six months ended December 31, 1996.

11. FINANCIAL INSTRUMENTS:

The Company's financial instruments consist of cash and cash equivalents,
notes receivable, notes payable, a line of credit and long-term debt. The
Company believes that the carrying value of these instruments on the
accompanying balance sheet approximates their fair value.

12. SIGNIFICANT CUSTOMERS AND VENDORS:

Significant customers are those that account for greater than ten percent
of the Company's revenues. For the year ended June 30, 1996 and the six months
ended December 31, 1996, one customer, a publicly traded Real Estate Investment
Trust, accounted for 14% and 20% of the Company's revenues, respectively.
Receivables outstanding from this customer represented 13% and 12% of the
Company's trade and retainage receivables as of June 30, 1996 and December 31,
1996, respectively. In addition, one of the Company's shareholders has less than
1% ownership in this customer.

During the years ended June 30, 1994, 1995 and 1996 and the six months
ended December 31, 1996, two vendors accounted for 12% and 11%; 29% and 17%; 20%
and 17%; and 15% and 12% of the Company's purchases, respectively.

13. EVENT SUBSEQUENT TO DATE OF AUDITORS' REPORT OF INDEPENDENT PUBLIC
ACCOUNTANTS (UNAUDITED):

In March 1997, the Company and its shareholders entered into a definitive
agreement with a wholly-owned subsidiary of Comfort Systems providing for the
merger of the Company with the subsidiary of Comfort Systems. On July 2, 1997,
Comfort Systems completed its initial public offering and the merger with the
Company.

Concurrently with the merger, the Company entered into agreements with the
shareholders to lease land and buildings used in the Company's operations for
negotiated amounts and terms.

In connection with the merger, Comfort Systems assumed all debt of the
Company. Subsequent to the IPO, substantially all of the debt has been repaid.

Effective January 1, 1996, the Company adopted Statement of Financial
Accounting Standards (SFAS) No. 121, "Accounting for the Impairment of
Long-Lived Assets and for Long-Lived Assets to Be Disposed Of." Accordingly, in

write-down to market value is necessary. Adoption of this standard did not have
a material effect on the financial position or results of operations of the
Company.

opinion on these combined financial statements based on our audits.

We conducted our audits in accordance with generally accepted auditing

estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.

In our opinion, the combined financial statements referred to above present
fairly, in all material respects, the financial position of S. M. Lawrence Inc.

1. BUSINESS AND ORGANIZATION:

S.M. Lawrence Inc., a Tennessee corporation (the "Company") focuses on
providing "design and build" installation services and process piping
primarily for industrial facilities and maintenance, repair and replacement of
commercial and industrial HVAC systems. S.M. Lawrence primarily operates in
Tennessee and the immediately surrounding states.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

BASIS OF PRESENTATION

The financial statements include the accounts and results of operations of
S.M. Lawrence Inc. and Lawrence Services, Inc. which are under common control
and management of two individuals. All significant intercompany transactions and
balances have been eliminated in combination.

INTERIM FINANCIAL INFORMATION

The interim combined financial statements as of June 30, 1997, and for the
eight months ended June 30, 1996 and 1997, are unaudited, and certain
information and footnote disclosures, normally included in financial statements
prepared in accordance with generally accepted accounting principles, have been
omitted. In the opinion of management, all adjustments, consisting only of
normal recurring adjustments, necessary to fairly present the financial
position, results of operations and cash flows with respect to the combined
interim financial statements, have been included. The results of operations for
the interim periods are not necessarily indicative of the results for the entire
fiscal year.

CASH AND CASH EQUIVALENTS

The Company considers all highly liquid investments purchased with an
original maturity of three months or less to be cash equivalents.

INVENTORIES

using an accelerated method of depreciation. Leasehold improvements are
capitalized and amortized over the lesser of the life of the lease or the
estimated useful life of the asset.

REVENUE RECOGNITION

is being performed under a construction contract. Revenues from construction
contracts are recognized on the percentage-of-

completion method measured by the percentage of costs incurred to total
estimated costs for each contract. Provisions for the total estimated losses on
uncompleted contracts are made in the period in which such losses are
determined. Changes in job performance, job conditions, estimated profitability
and final contract settlements may result in revisions to costs and income and
their effects are recognized in the period in which the revisions are
determined.

WARRANTY COSTS

The Company warrants labor and parts for one year after installation of new
air conditioning and heating systems. A reserve for warranty costs is recorded
upon completion of installation or service.

NEW ACCOUNTING PRONOUNCEMENT

Effective January 1, 1996, the Company adopted SFAS No. 121, "Accounting
for the Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed
Of." Accordingly, in the event that facts and circumstances indicate that
property and equipment, and intangible or other assets may be impaired, an
evaluation of recoverability would be performed. If an evaluation is required,
the estimated future undiscounted cash flows associated with the asset are
compared to the asset's carrying amount to determine if a write-down to market
value is necessary. Adoption of this standard did not have a material effect on
the financial position or results of operations of the Company.

accounting for income taxes in accordance with Statement of Financial Accounting
Standards (SFAS) No. 109. Under this method, deferred income taxes were recorded
based upon differences between the financial reporting and tax bases of assets

carrying value of approximately $370,000 as of June 30, 1997. The Company also
distributed approximately $101,000 to its shareholder as of June 30, 1997.

a company partially owned by the shareholder to lease land and buildings owned
by such party used in the Company's operations for a negotiated amount and term.

In connection with the merger, Comfort Systems assumed all debt of the
Company. Subsequent to the IPO, substantially all of the debt has been repaid.

The Company and its shareholder intends to enter into a definitive
agreement with Comfort Systems USA, Inc. ("Comfort Systems") pursuant to which
all outstanding shares of the Company's common stock will be exchanged for cash
and shares of Comfort Systems common stock concurrently with the consummation of
the initial public offering (the "Offering") of the common stock of Comfort
Systems.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

INTERIM FINANCIAL INFORMATION

CASH AND CASH EQUIVALENTS

The Company considers all highly liquid investments purchased with an
original maturity of three months or less to be cash equivalents.

INVENTORIES

Inventories consist of parts and supplies held for use in the ordinary
course of business and are stated at the lower of cost or market using the
first-in, first-out (FIFO) method.

<PAGE>
EASTERN HEATING AND COOLING, INC.
NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)

The balances billed but not paid by customers pursuant to retainage
provision in construction contracts will be due upon completion of the contracts
and acceptance by the customer. Based on the Company's experience with similar
contracts in recent years, the retention balance will be billed and collected in
the upcoming fiscal year.

WARRANTY COSTS

INCOME TAXES

The Company has elected S Corporation status as defined by the Internal
Revenue Code, whereby the Company is not subject to taxation for federal
purposes. Under S Corporation status, the shareholder reports his share of the
Company's taxable earnings or losses in his personal tax returns. The Company
will terminate its S Corporation status concurrently with the effective date of
this Offering.

USE OF ESTIMATES

NEW ACCOUNTING PRONOUNCEMENT

Effective January 1, 1996, the Company adopted Statement of Financial
Accounting Standards (SFAS) No. 121, "Accounting for the Impairment of
Long-Lived Assets and for Long-Lived Assets to Be Disposed Of." Accordingly, in
the event that facts and circumstances indicate that property and equipment, and
intangible or other assets may be impaired, an evaluation of recoverability
would be performed. If an evaluation is required, the estimated future
undiscounted cash flows associated with the asset are compared to the asset's
carrying amount to determine if a write-down to market value is necessary.
Adoption of this standard did not have a material effect on the financial
position or results of operations of the Company.

NEW ACCOUNTING PRONOUNCEMENT

Effective January 1, 1996, the Company adopted Statement of Financial
Accounting Standards (SFAS) No. 121, "Accounting for the Impairment of
Long-Lived Assets and for Long-Lived Assets to Be Disposed Of." Accordingly, in
the event that facts and circumstances indicate that property and equipment, and
intangible or other assets may be impaired, an evaluation of recoverability
would be performed. If an evaluation is required, the estimated future
undiscounted cash flows associated with the asset are compared to the asset's
carrying amount to determine if a write-down to market value is necessary.
Adoption of this standard did not have a material effect on the financial
position or results of operations of the Company.

SEASONAIR, INC.
NOTES TO FINANCIAL STATEMENTS

1. BUSINESS AND ORGANIZATION:

Seasonair, Inc., a Maryland corporation, (the "Company") focuses on
providing installation services and maintenance, repair and replacement of HVAC
systems for light commercial facilities. Seasonair primarily operates in
Maryland, the District of Columbia and Virginia.

INTERIM FINANCIAL INFORMATION

The interim financial statements as of June 30, 1997, and for the six
months ended June 30, 1996 and 1997, are unaudited, and certain information and
footnote disclosures, normally included in financial statements prepared in
accordance with generally accepted accounting princples, have been omitted. In
the opinion of management, all adjustments, consisting only of normal recurring
adjustments, necessary to fairly present the financial position, results of
operations and cash flows with respect to the interim financial statements, have
been included. The results of operations for the interim periods are not
necessarily indicative of the results for the entire fiscal year.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

CASH AND CASH EQUIVALENTS

The Company considers all highly liquid investments purchased with an
original maturity of three months or less to be cash equivalents.

INVENTORIES

PROPERTY AND EQUIPMENT

Property and equipment are stated at cost, and depreciation is computed
using an accelerated method over the estimated useful lives of the assets.
Leasehold improvements are capitalized and amortized over the lesser of the life
of the lease or the estimated useful life of the asset.

REVENUE RECOGNITION

The Company recognizes revenue when services are performed except when work
is being performed under a construction contract. Revenue from construction
contracts is recognized on the completed-contract method. This method is used
because the typical contract is completed within a twelve-month period, and the
Company's current financial position and results of operations do not vary
significantly from those which would result from use of the
percentage-of-completion method. A contract is considered complete when all
costs except insignificant items have been incurred, and the installation is
operating according to specifications or has been accepted by the customer.

F-110
<PAGE>
SEASONAIR, INC.
NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)

Contract costs include all direct equipment, material, labor, and
subcontract costs. Provisions for estimated losses on uncompleted contracts are
made in the period in which such losses are determined.

WARRANTY COSTS

INCOME TAXES

The Company follows the liability method of accounting for income taxes in
accordance with Statement of Financial Accounting Standards (SFAS) No. 109
"Accounting for Income Taxes". Under this method, deferred income taxes are
recorded based upon differences between the financial reporting and tax bases of
assets and liabilities and are measured using the enacted tax rates and laws
that will be in effect when the underlying assets or liabilities are recovered
or settled.

USE OF ESTIMATES

NEW ACCOUNTING PRONOUNCEMENT

Effective January 1, 1996, the Company adopted SFAS No. 121, "Accounting
for the Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed
Of." Accordingly, in the event that facts and circumstances indicate that
property and equipment and intangible or other assets may be impaired, an
evaluation of recoverability would be performed. If an evaluation is required,
the estimated future undiscounted cash flows associated with the asset are
compared to the asset's carrying amount to determine if a write-down to market
value is necessary. Adoption of this standard did not have a material effect on
the financial position or results of operations of the Company.

3. PROPERTY AND EQUIPMENT:

credit at December 31, 1996.

6. LEASES:

by one of the shareholders. The lease expires in October, 2006. The rent paid
under this lease was approximately $62,640 for the year ended December 31, 1996.
The lease requires the Company to pay taxes, maintenance, insurance and certain
other operating costs of the leased property.
