Comfort Systems USA Reports Second Quarter Results

Profits and Margins Increase Strongly on Higher Revenues
HOUSTON--(Business Wire)--
Comfort Systems USA, Inc. (NYSE:FIX), a leading provider of
commercial, industrial and institutional heating, ventilation and air
conditioning ("HVAC") services, today announced net income of
$15,193,000 or $0.38 per diluted share, for the quarter ended June 30,
2008, as compared to net income of $10,501,000 or $0.25 per diluted
share, in the second quarter of 2007.

Bill Murdy, Comfort Systems USA's Chairman and CEO, said, "We are
delighted to report that earnings per share increased by over 50%
compared to the same quarter a year ago. This improvement continues
our record of success and further demonstrates the productivity,
quality and dedication of our operations and outstanding workforce."

The Company reported revenues of $355,097,000 ($318,691,000 on a
same store basis) in the current quarter, as compared to $280,520,000
in 2007. The Company also reported free cash flow of $22,843,000 in
the current quarter, as compared to $19,079,000 in 2007. Backlog as of
June 30, 2008 was $780,156,000 compared to $811,255,000 as of March
31, 2008. On a same store basis, backlog as of June 30, 2008 was
$701,055,000 as compared to $719,967,000 on June 30, 2007. Backlog at
our Atlas subsidiary decreased by approximately $36,600,000 over the
same period, which more than accounted for the decrease in total
backlog.

Murdy continued, "Revenues were up significantly both on absolute
and same store measures. Backlog, although down slightly, remains at
or near record levels at the vast majority of our operations.
Importantly, same store backlog versus one year earlier has increased
excluding the purposeful decrease in backlog at our Atlas subsidiary."

The Company reported net income for the six months ended June 30,
2008 of $23,434,000 or $0.58 per diluted share, as compared to net
income of $12,307,000 or $0.30 per diluted share in 2007. The Company
also reported revenues of $650,802,000 for the first six months of
2008, as compared to $530,160,000 in 2007. Free cash flow for the six
months ended June 30, 2008 was $19,125,000 as compared to free cash
flow of $3,802,000 in 2007.

Bill Murdy concluded, "We are mindful of economic and financial
challenges that confront the economy. In light of the consistency of
our cash flows, the strength demonstrated in our backlog, and our
recent success in bringing strong new operations and their excellent
teams into the Comfort Systems USA family, we remain optimistic about
the second half of 2008. Even if a significant nonresidential
construction recession becomes fact, we believe that we can continue
to demonstrate impressive profitability and growth to the fundamental
value of Comfort Systems USA."

Note 1: The Company defines adjusted earnings before interest, taxes,
depreciation and amortization ("Adjusted EBITDA") as net income,
excluding income taxes, other income, interest income, net, gain on
sale of assets and depreciation and amortization. Other companies may
define Adjusted EBITDA differently. Adjusted EBITDA is presented
because it is a financial measure that is frequently requested by
third parties. However, Adjusted EBITDA is not considered under
generally accepted accounting principles as a primary measure of an
entity's financial results, and accordingly, Adjusted EBITDA should
not be considered an alternative to operating income, net income, or
cash flows as determined under generally accepted accounting
principles and as reported by the Company.

Note 1: Free cash flow is defined as cash flow from operating
activities less customary capital expenditures, plus the proceeds
from asset sales. Other companies may define free cash flow
differently. Free cash flow is presented because it is a financial
measure that is frequently requested by third parties. However, free
cash flow is not considered under generally accepted accounting
principles as a primary measure of an entity's financial results, and
accordingly, free cash flow should not be considered an alternative
to operating income, net income, or cash flows as determined under
generally accepted accounting principles and as reported by the
Company.
