Texas regulates HVAC contractors through the Texas Department of Licensing & Regulation (TDLR). To install, alter, or repair air conditioning or refrigeration equipment over 25 tons, a contractor must hold a Class A license; under 25 tons, a Class B license is sufficient. Endorsements such as RAS (Process Cooling), Hydronics, and Combustion appear on the license number itself. Licenses run on a one-year cycle and require continuing education for renewal. A licensed contractor must employ a Responsible A/C Contractor whose name appears on every active license record.
Every record on this page is published from the Texas Department of Licensing & Regulation All Licenses dataset and refreshed nightly. We display the status that TDLR published at last sync and re-derive each contractor’s verdict against the current date so the badge on a profile is honest about the moment you load the page.
