HVAC Contractor Licenses in Texas (2026 Guide)
Texas requires HVAC businesses to hold both an individual technician license and a separate contractor license through the Texas Department of Licensing and Regulation (TDLR). Unlike many states, Texas enforces this two-tier requirement strictly — operating without a licensed HVAC contractor on staff is a violation. Federal EPA certification for refrigerant handling is also mandatory for any work involving refrigerants.
