Verify the TDLR ACR license first
Every HVAC contractor operating in Austin must hold an Air Conditioning and Refrigeration Contractor (ACR) license issued by the Texas Department of Licensing and Regulation, and any ACR company must employ a licensed ACR contractor at each permanent location 3. Search the contractor's license number directly on TDLR's free license search tool and confirm it is active and matches the company name on your quote 4.
Ask whether the license is Class A, for unlimited tonnage work, or Class B, for limited capacity, and confirm that classification matches the scope of your project, particularly for larger homes or systems involving multiple zones.
Get comparable written bids
Collect two or three written estimates for any job over a couple thousand dollars, and insist each one lists the same core details: equipment brand and model, SEER2 rating, refrigerant type (R-410A versus newer R-454A/R-454B equipment), ductwork scope, and who is responsible for pulling the City of Austin mechanical permit.
Watch for bids that are vague on refrigerant type or ductwork scope, since Austin's older housing stock, especially in neighborhoods like Hyde Park and Tarrytown, often needs duct modifications that a lowball bid may quietly skip to look cheaper on paper.
Confirm permits and warranty terms in writing
Any HVAC replacement or new ductwork inside Austin city limits requires a mechanical permit filed through the Austin Build + Connect portal, and the job should be closed out with a final inspection 1. Get it in writing which party, you or the contractor, is responsible for filing that permit.
A trustworthy contract should also spell out warranty terms on both equipment and labor, and state the expected project timeline, especially important given that summer emergency-call backlogs can push non-urgent installs back by days or weeks.
Red flags to walk away from
Be cautious of door-to-door solicitors offering same-day deals after storms or heat emergencies, unusually large upfront cash deposits before any work begins, and contractors who cannot produce a TDLR ACR license number on request. These are common patterns behind complaints filed with TDLR against unlicensed or fly-by-night operators.
A legitimate, established Austin HVAC company will not hesitate to provide license verification, references, and a detailed written bid. If a contractor pressures you to sign same-day without time to compare bids, treat that as a signal to slow down and get a second opinion.

Common questions
How do I verify an HVAC company's license in Austin?
Search the contractor's license number on TDLR's license search tool at tdlr.texas.gov/verify.htm and confirm the ACR license is active and matches the company name on your quote.
How many quotes should I get for HVAC work in Austin?
Get at least two or three written estimates for any job over a couple thousand dollars, and make sure each lists the same equipment, refrigerant type, and permit responsibility so you can compare them fairly.
Who is responsible for pulling the HVAC permit in Austin?
Either the homeowner or the licensed contractor can pull the mechanical permit through the Austin Build + Connect portal, but it should be stated clearly in your written contract which party is responsible.
What red flags suggest an unlicensed or unreliable HVAC contractor?
Door-to-door solicitation after storms, large upfront cash deposits, pressure to sign same-day, and an inability to produce a TDLR ACR license number are all common warning signs.
Does the size of the company matter when choosing an HVAC contractor?
Not necessarily. What matters most is an active, verified TDLR ACR license, clear written bids, and a track record of pulling proper City of Austin permits, regardless of company size.
