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.

The Air Conditioning and Refrigeration Contractors Advisory Board met September 8 in Austin. The agenda and staff reports are online. The meeting was archived, and you can watch it with RealPlayer or on TDLR's YouTube page.

TDLR amended the Air Conditioning and Refrigeration (ACR) administrative rules on November 21, 2013, to implement changes in the ACR law created by Senate Bill 383, authored by Sen. John Carona and enacted into law in 2013 by the 83rd Texas Legislature.

The amended ACR rules took effect on January 1, 2014, and include a repeal of air conditioning refrigerant sales regulation by the Texas Department of Licensing and Regulation (TDLR), including the state certificate of registration to purchase refrigerants.  Senate Bill 383 and its related TDLR rules changes will remove overlapping federal and state regulatory requirements regarding refrigerant sales since the U.S. Environmental Protection Agency does and will continue to regulate these sales based on federal law.  Senate Bill 383 was a statutory change recommended by TDLR in its 2013-2017 Strategic Plan, entitled “Smaller, Smarter Government” to reflect the agency’s vision to reduce regulatory burdens on licensees and consumers.

Changes were also made to the continuing education rule requirements for air conditioning and refrigeration contractors, lowering the number of hours of instruction in state laws and rules required annually from two to one, effective with licenses that expire on or after June 1, 2014. The total number of continuing education hours required annually will remain at eight hours.
