How to Verify an HVAC Contractor's License in Texas in 30 Seconds (And Why Austin Homeowners Get Burned When They Skip This Step)
, 4 min reading time
If an unlicensed HVAC contractor damages your home during install, your homeowners insurance can deny the claim. If they skip the permit to "save you money," the buyer's inspector flags it when you sell your home. Don't risk thousands on a scam. Learn how to verify a Texas HVAC contractor in 30 seconds through the TDLR database and protect your Austin home.
Spend ten minutes on r/Austin and you will find a contractor horror story posted within the last week. AC replacement scams in Cedar Park. Bait pricing in Round Rock. A $14,000 quote in Westlake Hills for the same system that should cost $9,500. The pattern is consistent enough that "Austin HVAC" has become a punchline in homeowner forums.
Here is the part most homeowners do not know: most of those bad-actor stories trace back to contractors who were either unlicensed, operating outside their license type, or holding a license with an active complaint history. All of that information is public. All of it is searchable in 30 seconds. Almost no one checks.
This post is the checklist that closes the gap.
Why It Matters in Austin Specifically
Texas regulates HVAC contractors through TDLR (Texas Department of Licensing and Regulation). To do residential HVAC installation legally in Texas, a contractor needs:
-
An active TACLA license (the full installation and service license).
-
General liability and workers comp insurance.
-
A pulled mechanical permit for any full system replacement.
Plenty of operators in the Austin metro skip one or more of these. The reason it matters: if an unlicensed contractor damages your home during install, your homeowners insurance can deny the claim. If they fail to pull a permit and you later sell the house, the buyer's inspector flags it and you eat the cost of bringing it to code retroactively.
The 30-Second TDLR Lookup
-
Go to tdlr.texas.gov
-
Click "License Search" in the top navigation
-
Enter the contractor's license number (it should start with TACLA or TACLB)
-
Click search and read what comes back
What you will see: active or expired status, complaint history, the company name on file, and any disciplinary actions. If the contractor cannot give you a license number on the phone when you ask, that is your answer. Hang up.
For reference, our license is TACLA70281C. Plug it in before you read another sentence we publish.
TACLA vs TACLB: The One You Want
-
TACLA: full HVAC installation and service license. Authorized for any residential or commercial system. This is what you want for a full replacement.
-
TACLB: limited scope license. Restricted to systems under a specific tonnage threshold (typically smaller residential or window-unit-level work). A TACLB contractor doing a full 4-ton replacement on your Cedar Park home is operating outside their authorized scope.
Beyond the License: 5 Additional Checks
License verification gets you 80 percent of the way. The remaining 20 percent comes from these:
-
Ask for proof of insurance. A legitimate contractor emails you their certificate of insurance within an hour. A bad-actor delays, deflects, or sends an expired one.
-
Confirm they will pull the permit. The permit is filed by the contractor with your city (Austin, Cedar Park, Round Rock, etc.). It costs $80 to $200 and protects you. If they "skip the permit to save you money," walk away.
-
BBB lookup. Search the company name at bbb.org. Check for unresolved complaints in the last 24 months.
-
Next door. The Austin Nextdoor network is unusually active for HVAC recommendations. Search your specific neighborhood for the contractor's name. If they have been operating in Austin for more than 2 years and have zero Nextdoor mentions, something is off.
Red Flags That Mean Walk Away
-
Refuses to give a license number over the phone.
-
License number does not match the company name on TDLR.
-
"We can skip the permit to save you a few hundred."
-
Pressure to sign same-day for a discount.
-
Cash-only or check-payable-to-individual (not the LLC).
-
No physical Austin metro address verifiable on Google Maps.
-
Quote arrives without a written breakdown of equipment, labor, refrigerant, and warranty.
What to Do Next
Verify our license first: TACLA70281C at tdlr.texas.gov. Then, if you want a real itemized quote without anyone walking into your house, text 4 photos to (737) 214-2915. The outside unit, the unit in the attic, the model sticker, and your thermostat. We will send the full quote the same business day.
That is the entire process. No 2-hour living room presentation. No "today only" pricing. No mystery line items.
