Examination Specialists was incorporated in 1993 to provide education training to help candidates pass the Texas Air Conditioning and Refrigeration Contractor's License Examination. We are the only company that provides both hard cover and computer aided study guide. ESI sells all of the state required materials for the examination at a discounted price. In 2003 we acquired Mechanical Training Service to provide training and seminars for both EPA Section 608 and Contractor's Examination preparation. We also provide Continuing Education Units for Air Conditioning and Refrigeration Contractors, which the state has mandated for any license that is renewed on or after January 1, 2006.
