Air Conditioning and Refrigeration Contractors

Military Service Members, Veterans, and Spouses - For more information about obtaining a TDLR license or renewing a TDLR license that expired while serving on active duty, please go to the Military Outreach home page.

The Air Conditioning and Refrigeration program regulates contractors who install, repair, or maintain systems related to air conditioning, refrigeration, or heating.

The Texas Department of Licensing and Regulation (TDLR) would like to remind the owners of homes and businesses that contracting with an unlicensed individual for air conditioning and heating repairs can be hazardous.

News and Updates

2015 Mechanical Codes - Effective January 1, 2018

Adopted amendments to Administrative Rule §75.110 became effective January 1, 2018 and updated the code editions from the 2012 to the 2015 for the Uniform Mechanical Code, the International Mechanical Code, International Residential Code, and other applicable codes, including the International Energy Conservation Code, and International Fuel Gas Code.

Expectations are that any non-exempt air conditioning and refrigeration work permitted or started on or after January 1, 2018, be completed in accordance with the 2015 code editions.  Inside the corporate limits of a municipality, ACR Contractors must still abide by city permitting requirements and adhere to any local code amendments - contact your local code officials for related questions.

As of January 1, 2018, examinations for ACR Contractor licenses are also referenced to the 2015 Mechanical Codes. The state ACR Contractor exams are available through PSI, who contracts with TDLR to develop, maintain, and administer our licensing examinations. It is very important for license candidates to review the Candidate Information Bulletin (CIB) which contains detailed information regarding the examinations and is vital to understanding the process.

Want to Help Texas Air Conditioning and Refrigeration Contractors with Harvey Recovery?

TDLR offers two paths for out-of-state Air Conditioning and Refrigeration personnel to assist with the Harvey recovery efforts in Texas:

  1. Experienced ACR Technicians may quickly and easily obtain an ACR Technician Registration online.  Once an ACR Technician Registration is obtained, you may coordinate with a Texas licensed ACR Contractor and immediately begin performing ACR work in Texas.  Apply for Technician Registration online.
  2. Texas currently has reciprocal ACR Contractor licensing agreements with two states, South Carolina and Georgia. TDLR will fast-track reciprocal license applications from those states, so that qualified applicants wanting to assist with the Harvey recovery efforts may quickly obtain a reciprocal license and begin performing ACR work in Texas.  More information on how to apply by reciprocity.
