         Shareholders Urged to Prevent Additional
       Stock Option Repricing at Comfort Systems USA


  Shareholders of Comfort Systems USA (NYSE: FIX - news) will
  be asked at the company's next annual meeting to vote on a
  proposal urging the Board of Directors to seek approval of
  the majority of shareholders before repricing stock options
  already given or issuing new lower-priced options because
  the market price has dropped below the exercise price of the
  options.

  The proposal, sponsored by the Sheet Metal Workers'
  International Association(SMWIA) is responding to an
  admission by Comfort Systems that the company recently
  awarded its executives additional stock options because of a
  declining stock price.  The company revealed this in its
  year 2000 proxy statement.

       "In late 2000, an aggregate of 300,000 options were
       granted to five individuals excluding Mr. Murdy with
       existing options because the previous options granted
       to these individuals were at exercise prices
       significantly higher than year end 2000 market value."

  The SMWIA believes the repricing of options (or granting new
  options) solely because the exercise price is below market
  value is unfair to shareholders.  The SMWIA believes
  repricing or replacing underwater options not only reduces
  executives' incentive to work hard for shareholders, but
  also tends to mislead shareholders about the true value of
  someone's compensation.

  "A deal is a deal, or should be," says SMWIA General
  President Michael J. Sullivan.  "Corporate executives often
  justify their high compensation by claiming much of it
  depends on stock price.  However, that ceases to be true if
  the stock dives but the options just get replaced by new
  cheaper options."

  A similar proposal co-sponsored by New York State Common
  Retirement Fund and the International Brotherhood of
  Electrical Workers won 46% of the vote cast at the 2001
  annual meeting of Sprint.
