FOR IMMEDIATE RELEASE

COMFORT SYSTEMS USA REPORTS THIRD QUARTER RESULTS

—    Net Income Increases 46% on Strong Revenues    —

Houston, TX — November 1, 2006 — 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 $8,962,000 or $0.22 per diluted share, for the quarter ended September 30, 2006, as compared to net income of $6,131,000 or $0.15 per diluted share, in the third quarter of 2005.

Bill Murdy, Comfort Systems USA’s Chairman and CEO, said, “The employees of Comfort Systems continued to raise the bar of excellence in the third quarter by creating net income for our stockholders that was 46% higher than the same quarter a year ago.”

The Company reported revenues from continuing operations of $287,676,000 in the current quarter, an increase of 22.3% as compared to $235,252,000 in 2005.  The Company also reported free cash flow of $3,265,000 in the current quarter as compared to free cash flow of $6,630,000 in 2005.  Backlog as of September 30, 2006 was $678,858,000, compared to $689,993,000, as of June 30, 2006 on a same store basis.  Backlog as of September 30, 2005 was $634,093,000 on a same store basis.

Murdy continued, “Backlog levels remain very high, and should support continued activity level increases.  As in the second quarter, our multi-family backlog declined somewhat while our remaining book of business continued to experience a backlog increase.  We believe that the shift of our backlog composition toward other market segments as well as productivity improvement we expect in our underperforming multi-family sector are positive factors for future bottom line performance.”

The Company reported net income for the nine months ended September 30, 2006 of $21,210,000 or $0.52 per diluted share as compared to net income of $11,338,000 or $0.28 per diluted share in 2005.  The Company reported net income from continuing operations for the nine months ended September 30, 2006 of $21,218,000 or $0.52 per diluted share as compared to net income from continuing operations of $12,259,000 or $0.31 per diluted share for the nine months ended September 30, 2005.  The Company reported revenues of $788,451,000 from continuing operations for the first nine months of 2006, as compared to $658,899,000 in 2005.

Bill Murdy concluded, “Internal and external indicators remain positive for nonresidential building construction.  We are continuing to invest in growth and improvement, and we remain optimistic as we head into the fourth quarter and 2007.”

As previously announced, the Company will host a conference call to discuss its financial results and position in more depth on Thursday, November 2, 2006 at 10:00 a.m. Central Time.  The call-in number for this conference call is 1-210-839-8504.  A replay of the entire call will be available until 6:00 p.m. Central Time, Thursday, November 9, 2006 by calling 1-402-530-8074.
