How to check an HVالتكييف contractor's license in Texas

Anyone who installs or repairs air conditioning in Texas for pay must hold, or work under, an A/C contractor license from TDLR.

1. Ask the contractor for its license number. It starts with TACLA (Class A, any size) or TACLB (Class B, up to 25 tons cooling).
2. Search the number or company name at TDLR License Search.
3. Confirm the status is active and the expiration date is in the future.
4. Check the name on the license matches the company on your contract.
