Performance Restricted Stock Award Agreement

Comfort Systems USA, Inc.
777 Post Oak Blvd, Suite 500
Houston, Texas 77056

Ladies and Gentlemen:

        The undersigned ("Employee") (i) acknowledges that he or she has
received an award (the "Award") of performance restricted stock from Comfort
Systems USA, Inc., a Delaware corporation (the "Company"), under the Company's
2006 Equity Incentive Plan (the "Plan"), subject to the terms set forth below
and in the Plan; (ii) further acknowledges receipt of a copy of the Plan as in
effect on the date hereof; and (iii) agrees with the Company as follows:

1.Effective Date.    This Agreement shall take effect as [Date], which is the
date of grant of the Award.

2.Shares Subject to Award.    The Award consists of [Number] shares (the
"Shares") of common stock of the Company ("Stock"). Employee's rights to the
Shares are subject to the restrictions described in this Agreement and the Plan
(which is incorporated herein by reference with the same effect as if set forth
herein in full) in addition to such other restrictions, if any, as may be
imposed by law. In the event that any provision of this Agreement is
inconsistent with the terms of the Plan, the terms of the Plan shall govern.

3.Meaning of Certain Terms.    Except as otherwise expressly provided in this
Agreement, all terms used herein shall have the same meaning as in the Plan. The
term "vest" as used herein with respect to any Share means the lapsing of the
restrictions described herein and in the Plan with respect to such Share, which
entitles Employee to transfer the Share and to retain such Share after a
termination of employment.

4.Nontransferability of Shares.    The Shares acquired by Employee pursuant to
this Agreement shall not be sold, transferred, pledged, assigned or otherwise
encumbered or disposed of until such time as they become vested under Section 7
of this Agreement.

5.Forfeiture Risk.    Except as provided in Section 7(c) of this Agreement, if
Employee ceases to be employed by the Company and its subsidiaries for any
reason, including death, any then unvested Shares acquired by Employee hereunder
shall be immediately forfeited upon such termination with no consideration due
to Employee. Employee hereby (i) appoints the Company as his or her
attorney-in-fact to take such actions as may be necessary or appropriate to
effectuate a transfer of the record ownership of any such Shares that are
unvested and forfeited hereunder, (ii) agrees to deliver to the Company, as a
precondition to the issuance of any certificate or certificates with respect to
unvested Shares hereunder, one or more stock powers, endorsed in blank, with
respect to such Shares, and (iii) agrees to sign such other powers and take such
other actions as the Company may reasonably request to accomplish the transfer
or forfeiture of any unvested Shares that are forfeited hereunder.

6.Retention of Certificates.    Any certificates representing unvested Shares
shall be held by the Company. Employee agrees that the Company may give stop
transfer instructions to the depository to ensure compliance with the provisions
hereof.

--------------------------------------------------------------------------------

7.Vesting of Shares.    The Shares acquired hereunder shall vest in accordance
with the provisions of this Section 7 and applicable provisions of the Plan, as
follows:

(a)(i)    If the Committee determines that, for the prior 12-month period
preceding the first scheduled vesting date set forth in Section 7(b) herein, the
Company did not have positive earnings from its continuing operations, all as
determined and reported in accordance with generally accepted accounting
principles in the Company's regularly-prepared financial statements, excluding
the following non-cash items: (A) good will impairment; (B) write-off of debt
costs; (C) restructuring charges; and (D) any cumulative effect of a change in
accounting principles, Employee shall immediately and irrevocably forfeit all of
the Shares with no consideration due to Employee.

(ii)    If the Committee determines that for the 12-month period prior to the
date that such Shares are scheduled to vest under Section 7(b) herein the
Company's prior 36-month performance did not achieve 60% of the average 3-year
trailing EBITDA or EPS target (whichever the case may be) as set by the
Committee under the average of the Company's prior 3-year Senior Management
Incentive Programs, then Employee shall immediately and irrevocably forfeit all
of the Shares scheduled to vest on such date with no consideration due to
Employee.

(iii)    If in the 12-month period preceding a scheduled vesting date under
Section 7(b), the Company achieved between 60% to 80% of the average 3-year
trailing EBITDA or EPS target (whichever the case may be) as set by the
Committee under the average of the Company's prior 3-year Senior Management
Incentive Programs, then Employee shall immediately and irrevocably forfeit
Shares proportionately based on a scale where 60% or less equals 0% of Shares
retained by Employee and 80% or greater equals 100% of Shares retained by
Employee; and all Shares not forfeited pursuant to the aforementioned scale
shall vest on such vesting date.

(b)Subject to Section 7(a) above and Sections 7(c) and 7(d) below, and provided
that Employee is then, and since the date of grant has continuously been,
employed by the Company or its subsidiaries, then the Shares shall vest as
follows:

[1/3 of Number] on May 15, [2010];

[1/3 of Number] on April 1, [2011]; and

[1/3 of Number] on April 1, [2012].

provided, however, that, not withstanding anything to the contrary in
Section 7(a) above or this Section 7(b), any unvested Shares that have not
earlier been forfeited shall vest immediately in the event of (i) a "Change in
Control," as defined in Employee's change in control agreement, if any, with the
Company, or (ii) if Employee and Company have not entered into a change in
control agreement, in the event the Company experiences a "Change in Control" as
defined herein.

(c)Notwithstanding anything to the contrary in Section 7(b) above, if Employee
retires from the Company at a time when the sum of his or her age in whole years
and his or her years of service with the Company (as determined in a manner
consistent with the method used for purposes of determining vesting under the
Comfort Systems USA, Inc. 401(k) Plan) is at least 75, Employee shall be deemed
to satisfy the continuous employment condition set forth in Section 7(b) on each
vesting date following retirement. The number of Shares that vest will in all
cases be determined in accordance with the provisions of Section 7(a) above.

(d)Notwithstanding anything to the contrary in Sections 7(a), 7(b), or 7(c)
above, the Committee may, in its sole discretion, reduce the number of Shares
vesting on any date pursuant to this Award, and may cause any unvested Shares
under this Award to be forfeited, based on the individual performance of
Employee as compared with specific

--------------------------------------------------------------------------------

individual goals, which may be based on objective or nonobjective factors
related to Employee's performance.

8.Legend.    Any certificates representing unvested Shares shall be held by the
Company, and any such certificate shall contain a legend substantially in the
following form:

THE TRANSFERABILITY OF THIS CERTIFICATE AND THE SHARES OF STOCK REPRESENTED
HEREBY ARE SUBJECT TO THE TERMS AND CONDITIONS (INCLUDING FORFEITURE) OF THE
COMPANY'S 2006 EQUITY INCENTIVE PLAN AND A PERFORMANCE RESTRICTED STOCK AWARD
AGREEMENT ENTERED INTO BETWEEN THE REGISTERED OWNER AND COMFORT SYSTEMS
USA, INC. COPIES OF SUCH PLAN AND AGREEMENT ARE ON FILE IN THE OFFICES OF
COMFORT SYSTEMS USA, INC.

As soon as practicable following the vesting of any such Shares the Company
shall cause a certificate or certificates covering such Shares to be delivered
to Employee.

9.Voting Rights; Dividends, etc.    As of the date of grant, Employee shall have
the right to vote the Shares (to the same extent as any other holder of Stock),
and the right, subject to this Section 9, to receive dividends on the Shares,
unless and until the Shares are forfeited as provided for in Section 7 of this
Agreement. Unless the Committee determines otherwise, payment of any cash
dividend, additional shares of Stock, any other securities of the Company and
any other property distributed with respect to the Shares shall be deferred
until the Shares vest and are no longer subject to forfeiture under the terms of
this Agreement (and shall be subject to forfeiture upon forfeiture under
Section 7 above of any unvested Shares to which such deferred dividends relate).
The dividends or distributions allocable to the Shares shall be paid or
delivered to the Participant on the vesting date for the Shares to which the
dividends or distributions relate, but only to the extent such Shares vest under
the terms of this Agreement.

10.Sale of Vested Shares.    Employee understands that he or she will be free to
sell any Share only once it has vested, subject to (i) satisfaction of any
applicable tax withholding requirements with respect to the vesting or transfer
of such Share; (ii) the completion of any administrative steps (for example, but
without limitation, the transfer of certificates) that the Company may
reasonably impose; and (iii) applicable company policies and the requirements of
federal and state securities laws.

11.Certain Tax Matters.    Employee expressly acknowledges the following:

a.Employee has been advised to confer promptly with a professional tax advisor
to consider whether Employee should make a so-called "83(b) election" with
respect to the Shares. Any such election, to be effective, must be made in
accordance with applicable regulations and within thirty (30) days following the
grant date of this Award. The Company has made no recommendation to Employee
with respect to the advisability of making such an election.

b.The award or vesting of the Shares acquired hereunder, and the payment of
dividends with respect to such shares, may give rise to "wages" subject to
withholding. Employee expressly acknowledges and agrees that his or her rights
hereunder are subject to his or her satisfaction of any applicable tax
withholdings associated with such award, vesting or payment by: (i) delivering
cash (including check, money order or wire transfer made payable to the order of
the Company), (ii) having the Company withhold a portion of the Shares to be
delivered hereunder having a Fair Market Value equal to the minimum tax
withholding amount for such taxes, or (iii) delivering to the Company shares of
Stock having a Fair Market Value equal to the minimum tax withholding amount for
such taxes.

--------------------------------------------------------------------------------

12.Definition: Change in Control.    For the purpose of Section 7(b)(ii) herein,
a "Change in Control" shall be deemed to have occurred if:

a.any person (including any "person" within the meaning of Section 13(d)(3) or
14(d)(2) of the Securities Exchange Act of 1934, as amended, and more than one
person acting as a group), other than the Company, or an employee benefit plan
of the Company, or any entity controlled by either, acquiring directly or
indirectly the beneficial ownership of any voting security of the Company and if
immediately after such acquisition such person is, directly or indirectly, the
beneficial owner of voting securities representing 50% or more of the total
voting power of all of the then-outstanding voting securities of the Company,
provided that if any one person, or more than one person acting as a group,
owned more than 50% of the total fair market value or total voting power of
Company stock as of the date of this Agreement, the acquisition of additional
stock by the same person or persons shall not be deemed to be a Change in
Control;

b.the date a majority of the following individuals are replaced during any
12-month period by directors whose appointment or election is not endorsed by a
majority of the members of the Company's Board of Directors before the date of
the appointment or election: (i) the individuals who, as of the date hereof,
constitute the Board of Directors of the Company (the "Original Directors");
(ii) the individuals who thereafter are elected to the Board of Directors of the
Company and whose election, or nomination for election, to the Board of
Directors of the Company was approved by a vote of at least two-thirds of the
Original Directors then still in office (such directors becoming "Additional
Original Directors" immediately following their election); and (iii) the
individuals who are elected to the Board of Directors of the Company and whose
election, or nomination for election, to the Board of Directors of the Company
was approved by a vote of at least two-thirds of the Original Directors and
Additional Original Directors then still in office (such directors also becoming
"Additional Original Directors" immediately following their election); or

c.any one person, or more than one person acting as a group, acquiring (or who
has acquired during the 12-month period ending on the date of the most recent
acquisition by such person or persons) assets from the Company that have a total
gross fair market value equal to or more than 50% of the total gross fair market
value of the assets of the Company immediately before such acquisition or
acquisitions.

13.Non-Competition Agreement.    Employee will not, during the period of
employment by or with the Company, and for a period of twelve (12) months
immediately following the termination of employment, for any reason whatsoever,
directly or indirectly, on his or her own behalf or on behalf of or in
conjunction with any other person, company, partnership, corporation or business
of whatever nature:

a.engage, as an officer, director, shareholder, owner, partner, joint venturer,
or in a managerial capacity, whether as an employee, independent contractor,
consultant or advisor, or as a sales representative, or make guarantee loans or
invest, in or for any business engaged in the business of mechanical contracting
services, including heating, ventilation and air conditioning, plumbing, fire
protection, piping and electrical and related services ("Services") in
competition with the Company or any of its affiliates within seventy-five
(75) miles of where the Company or any affiliated operation or subsidiary
conducts business if within the preceding two (2) years Employee has had
responsibility for, or material input or participation in, the management or
operation of such other operation or subsidiary;

b.call upon any person who is, at that time, an employee of the Company or any
of its affiliates in a technical, managerial or sales capacity for the purpose
or with the intent of enticing such employee away from or out of the employ of
the Company or any affiliate;

--------------------------------------------------------------------------------

c.call upon any person or entity which is at that time, or which has been within
two (2) years prior to that time, a customer of the Company or any affiliate for
the purpose of soliciting or selling Services; or

d.call upon any prospective acquisition candidate, on Employee's own behalf or
on behalf of any competitor, which acquisition candidate either was called upon
Employee on behalf of the Company or any affiliate or was the subject of an
acquisition analysis made by Employee on behalf of the Company or any affiliate
for the purpose of acquiring such acquisition candidate.

Notwithstanding the above, the foregoing agreements and covenants shall not be
deemed to prohibit Employee from acquiring as an investment not more than one
percent (1%) of the capital stock of a competing business whose stock is traded
on a national securities exchange or on an over-the-counter or similar market.
It is specifically agreed that the period during which the agreements and
covenants of Employee made in this Section 13 shall be effective shall be
computed by excluding from such computation any time during which Employee is in
violation of any provision of this Section 13.

14.Remedies in the Event of Breach.    If the Company determines that Employee
is not in compliance with the agreements and covenants set forth in Section 13
above, and such non-compliance has not been authorized in advance in a specific
written waiver from the Company, the Committee may, without limiting other
remedies that may be available to the Company, cause all or any portion of the
Award to be forfeited, whether or not previously vested, and may require
Employee to remit or deliver to the Company the amount of any consideration
received by Employee upon the sale of any Shares delivered under the Award.
Employee acknowledges and agrees that the calculation of damages from a breach
of the foregoing agreements and covenants would be difficult to calculate
accurately and that the remedies provided for herein are reasonable and not a
penalty. Employee further agrees not to challenge the reasonableness of this
provision even if the Company rescinds or withholds the delivery of Shares
hereunder or withholds any amount otherwise payable to Employee as an offset to
effectuate the foregoing.

15.Entire Agreement.    The Plan and this Agreement constitute the entire
agreement of the parties and supersede in their entirety all prior undertakings
and agreements of the Company and Employee with respect to the subject matter
hereof.

        Very truly yours,
