ITEM 4.  Changes in Registrant's Certifying Accountant.

         On May 23, 2002, the Audit Committee of the Board of Directors of
Comfort Systems USA, Inc. (the "Company") decided, with the approval of the
Company's Board of Directors, that effective May 24, 2002 the Company would no
longer engage Arthur Andersen LLP ("Arthur Andersen") as the Company's
independent public accountants and that as of May 24, 2002 Ernst & Young LLP,
certified public accountants, would be appointed as the Company's independent
public accountants for 2002.

         The reports of Arthur Andersen on the Company's consolidated financial
statements for the past two years did not contain an adverse opinion or
disclaimer of opinion, nor were they qualified or modified as to uncertainty,
audit scope or accounting principles.

         During the Company's two most recent fiscal years and through May 24,
2002, there were no disagreements with Arthur Andersen on any matter of
accounting principles or practices, financial statement disclosure, or auditing
scope or procedure which, if not resolved to Arthur Andersen's satisfaction,
would have caused it to make reference thereto in connection with its report on
the Company's consolidated financial statements for such years; and there were
no reportable events as such term is used in Item 304(a)(1)(v) of Regulation
S-K.

         The Company provided Arthur Andersen with a copy of the foregoing
disclosures. Attached as Exhibit 16 is a copy of Arthur Andersen's letter, dated
May 24, 2002, stating its agreement with such statements.

         During the Company's two most recent fiscal years and through May 24,
2002, the Company did not consult Ernst & Young LLP with respect to the
application of accounting principles to a specified transaction, either
completed or proposed, or the type of audit opinion that might be rendered on
the Company's consolidated financial statements, or any other matters or
reportable events as set forth in Items 304(a)(2)(i) and (ii) of Regulation S-K.
