What license does an HVAC contractor need in Texas?

In Texas, HVAC contractors must hold an A/C Contractor license (for companies) or an A/C Technician license (for individual technicians), both issued by the Texas Department of Licensing and Regulation (TDLR). Working without an active license is illegal and can void your homeowner’s insurance.

TDLR stands for the Texas Department of Licensing and Regulation. It is the state agency responsible for licensing and regulating HVAC contractors, electricians, cosmetologists, and dozens of other professions in Texas.

Does an HVAC technician need a separate license from the contractor?

Yes. In Texas, the contracting company must hold an A/C Contractor license, and individual technicians performing work must hold an A/C Technician license. Both are issued and tracked by TDLR. You can verify either type using the search tool above.

What HVAC License Is Required in Texas?

Texas requires all HVAC contractors to be licensed by TDLR. There are two primary license types:

A/C Contractor — required for the business or company performing HVAC work
A/C Technician — required for individual technicians performing hands-on work

Hiring an unlicensed HVAC contractor can void your homeowner’s insurance, result in failed inspections, and leave you with no legal recourse if the work is done incorrectly.
