Texas HVAC license guide
Texas calls this the Air Conditioning and Refrigeration Contractors program. Use the TDLR ACR pages to confirm contractor licensing, class A/B limits, endorsements, exams, insurance, and renewal rules.
The short answer
In Texas, contractors who install, repair, or maintain air conditioning, refrigeration, or heating systems need a TDLR Air Conditioning and Refrigeration Contractor license. ACR companies also need an ACR contractor in each permanent location, according to TDLR.
Who this applies to
- HVAC contractors installing, repairing, or maintaining AC, refrigeration, or heating systems in Texas should review TDLR's ACR contractor license path.
- Companies with permanent locations need an ACR contractor in each permanent location.
- Technician registration/certification and contractor licensing are separate paths, so pick the official path that matches the work and business role.
