REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS To the Board of Directors and Stockholders  of EMCOR Group, Inc.: In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2001 and 2000, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2001, in conformity with accounting principles generally accepted in the United States. We have audited the accompanying consolidated balance sheets of EMCOR Group, Inc. (a Delaware corporation) and subsidiaries (the “Company”) as of December 31, 2001 and 2000, and the related consolidated statements of operations, cash flows and stockholders’ equity and comprehensive income for each of the three years in the period ended December 31, 2001. These consolidated financial statements and the schedule referred to below are the responsibility of the Company’s management. Our responsibility is to express an opinion on these consolidated financial statements and schedule based on our audits. Our audits were made for the purpose of forming an opinion on the basic financial statements taken as a whole. The schedule of Valuation and Qualifying Accounts is presented for purposes of complying with the Securities and Exchange Commission’s rules and is not part of the basic financial statements. This schedule has been subjected to the auditing procedures applied in the audits of the basic financial statements and, in our opinion, fairly states in all material respects the financial data required to be set forth therein in relation to the basic financial statements taken as a whole. ARTHUR ANDERSEN LLP We conducted our audits in accordance with auditing standards generally accepted in the United States. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis  for our opinion. Stamford, Connecticut February 20, 2002
