  Item 4.01 Changes in Registrant's Certifying Accountant.
  (a) Previous Independent Registered Public Accounting Firm:
  On April 25, 2006, the Hanover Companies Retirement Savings Plan (the "Plan") dismissed PricewaterhouseCoopers LLP ("PwC") as the Plan's independent registered public accounting firm. The dismissal was approved by the Audit Committee of the Board of Directors of Hanover Compressor Company.
  The reports of PwC on the Plan's financial statements for the years ended December 31, 2004 and 2003 contained no adverse opinion or a disclaimer of opinion and were not qualified or modified as to uncertainty, audit scope or accounting principle.
  During the years ended December 31, 2004 and 2003 and through April 25, 2006, there have been no disagreements with PwC on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which disagreements, if not resolved to the satisfaction of PwC would have caused PwC to make reference thereto in its reports on the Plan's financial statements for such years. During the years ended December 31, 2004 and 2003 and through April 25, 2006, there were no "reportable events" as described in Item 304(a)(1)(v) of Regulation S-K.
  The change in the accounting firm described above pertains only to the financial statements of the Plan and does not affect PwCs engagement as the independent registered public accounting firm of Hanover Compressor Company.
  PwC has been provided with a copy of the foregoing statements. Attached as Exhibit 16.1 to this 8-K is a copy of PwC's letter dated May 1, 2006 stating its agreement with such statements.

  The Audit Committee of the Board of Directors of Hanover Compressor Company appointed Melton & Melton, LLP as the Plan's new independent registered public accounting firm for the year ended December 31, 2005, as of April 25, 2006. During the years ended December 31, 2004 and 2003 and through April 25, 2006, the Plan did not consult with Melton & Melton, L.L.P. on any accounting or auditing matter pursuant to Item 304(a)(2)(i) and Item 304(a)(2)(ii) of Regulation S-K.
