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.

What happens if an HVAC contractor has an expired license?

Hiring an HVAC contractor with an expired or invalid TDLR license is risky. The work may not be up to code, permits may be denied, and your homeowner’s insurance could refuse to cover damage from unlicensed work. If a contractor’s license doesn’t check out, our tool shows pre-vetted alternatives in the Forney area.

Is this TDLR license lookup tool free?

Yes. This tool is completely free for homeowners. It pulls data directly from the Texas Open Data Portal (TDLR records) in real time. There is no registration or cost to use it.

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. All A/C contractors and technicians must hold an active TDLR license to legally work in the state.

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.
