Verify a Texas HVAC license — any contractor's, including ours.
Texas licenses air-conditioning contractors through the Texas Department of Licensing and Regulation. Anyone can look one up, free, in under a minute. Here is how, what the record means, and where our own numbers lead.
How to look up any Texas HVAC contractor
- Open TDLR License Search.
- Choose the license type Air Conditioning Contractors.
- Type the license number and press Search. Ours is 52456.
TDLR shows the number with leading zeros — ours reads TACLB00052456E on the record and TACLB52456E on the truck and the license card. It is one license.
You can verify any Texas HVAC contractor free at TDLR License Search: choose "Air Conditioning Contractors" and enter the license number. Ours is 52456.
Air conditioning and refrigeration work in Texas must be performed through a TDLR-licensed Air Conditioning and Refrigeration Contractor.
What the record means
A Class B license covers systems up to 25 tons of cooling capacity or 1.5 million Btu per hour of heating output — every residential and light-commercial system.
Texas law requires every air conditioning contracting company to employ a licensed contractor full-time in each permanent office; a company without one cannot enforce its contract or collect a fee.
Texas requires every licensed air-conditioning and refrigeration contracting company to show its affiliated licensee's license number in all advertising that solicits business (16 TAC §75.71(h)).
Ours
Texas air-conditioning license TACLB52456E (license number 52456). TDLR lists the licensed contractor of record for that number, the class held, and the expiration date — look it up rather than take it from us.
TDLR's public record for license 52456 types the business name as "AVANELLA HOMES LLC" with a DBA "AVANELLE HVAC" — a spelling on the state's record, not a different company. A correction has been requested.
The City of San Antonio registration
A different credential covers repairs and remodels: the City's Home Improvement Contractor registration. Ours is HIC-26-00132. It is a registration, not a trade license, and it is not the HVAC credential — the facts below say exactly what it covers.
A City of San Antonio Home Improvement Contractor registration covers repairs, replacements and remodels of existing homes (City Code Sec. 10-25).
In San Antonio, mechanical (heating and air-conditioning) work is regulated separately from home-improvement registration (City Code Sec. 10-116), and the City requires the state TDLR license for it (Sec. 10-114) — a Home Improvement Contractor registration is not the HVAC credential.
A San Antonio Home Improvement Contractor registration is valid for two years and must be renewed every two-year period.
To hold a Home Improvement Contractor registration, a contractor must pass an FBI criminal background check and keep liability insurance on file with the City of San Antonio.
Structural work on a San Antonio home — new construction, structural alterations, additions and foundation repairs — requires the City's separate Residential Building Contractor registration.
You can look up any City-registered contractor by registration number or company name in the City of San Antonio's Contractor Connect search.
What Texas does not license
A company that calls itself "licensed" for work Texas does not license is telling you something about itself. These are the trades with no state license to check:
Texas does not require a state-issued license for roofing contractors; a 2025 Texas House bill to create one did not pass.
Texas has no state license for general contractors, window installers or foundation repair companies — TDLR licenses air conditioning and electrical contractors, among other trades, but none of these.
What a proposal or invoice must carry
Every proposal and invoice from a Texas air-conditioning contractor must carry the company's name, address, phone number and license number (16 TAC §75.71(i)).
Texas rule 16 TAC §75.71(i) requires that notice on every proposal, invoice and written contract from an air-conditioning contractor.
