TACLA vs TACLB: Texas HVAC License Types Explained
If you've ever tried to verify an HVAC contractor's Texas license and run into terms like TACLA, TACLB, or ACR, you're not alone. Here is what each one means, why the distinction matters, and how to check any license in about 30 seconds.
The Two Active Texas HVAC License Types
TACLB - Air Conditioning Contractor License
A TACLB license is held by the contracting company, not an individual. If an HVAC business is legally operating in Texas, the company must hold a TACLB. This is the license you should ask for when getting a quote from any HVAC company. A valid TACLB means the business is registered with the state, carries required insurance, and is legally permitted to contract for HVAC work.
TACLA - Air Conditioning Technician License
A TACLA license is held by the individual technician performing hands-on work. In Texas, the technician who diagnoses your system, handles refrigerant, or performs the repair must hold their own active TACLA. A company can hold a TACLB while its technicians each carry individual TACLAs.
ACR - Legacy Format
ACR is an older license number format still held by some long-established contractors. It covers the same contractor function as a TACLB. If you see an ACR number, it is a legitimate Texas HVAC license -- just an older issue date.
Why This Matters Before You Hire
Hiring an unlicensed HVAC contractor or technician in Texas creates real risk:
- Equipment manufacturer warranties are typically voided by unlicensed work
- City and county inspections can fail, blocking a home sale or triggering required re-work at your cost
- Improper refrigerant handling by an unlicensed technician is a federal violation
- You have limited legal recourse if the work fails and the contractor has no state license to file a complaint against
Texas law requires both the contracting company (TACLB) and the technician (TACLA) to hold active licenses. Verifying both takes less than a minute.

Frequently Asked Questions
Does my HVAC contractor need both a TACLA and a TACLB?
The company needs a TACLB. Each technician who performs work needs a TACLA. They are separate licenses -- a technician's TACLA does not cover the company, and the company's TACLB does not cover an individual technician working independently.
What if a contractor can't provide a license number?
That is a clear warning sign. Any licensed Texas HVAC contractor or technician can give you their TDLR license number on request. If they can't or won't, do not hire them.
Is TDLR the same as a city or county license?
No. TDLR is a state-level license required across all of Texas. Some cities and counties add their own permit requirements on top of the state license. The TDLR license is the baseline -- it does not replace local permit requirements.
How often do Texas HVAC licenses expire?
TDLR licenses require renewal. Expiration dates vary by contractor. The live lookup tool shows current expiration, so you can confirm the license is active at the time you hire, not just that it was active at some point.
