How to Choose an HVAC Company in Austin, TX

How to choose an HVAC company in Austin

Austin has a long list of HVAC companies, from national brands to one-truck shops, and the right one depends on the job. These checks take a few minutes and filter out most of the problems before anyone comes to your house.

1. Check the license

Texas licenses air conditioning and refrigeration contractors through the Texas Department of Licensing and Regulation. Ask for the license number and look it up at tdlr.texas.gov. You will see the license holder, the license class and whether it is active.

2. Ask about permits

Replacement work inside Austin city limits generally needs a permit and an inspection. A company that suggests skipping the permit to save money is telling you something.

3. Read reviews for patterns

Look past the star rating to what reviews say. Do customers mention being quoted before work started, the same technician by name, and problems handled when something went wrong? A few bad reviews answered well can say more than a wall of perfect ones.

Red flags

A replacement quote with no explanation of why the system cannot be repaired.
Refrigerant top-ups every year with no search for the leak.
Pressure to sign today for a "today only" price.
A price quoted over the phone for a repair nobody has diagnosed.
No written estimate or warranty terms.

For a new system, a few more

Ask for a load calculation, the SEER2 rating in writing, confirmation that the indoor and outdoor units are a matched pair, and, if you are an Austin Energy customer, whether the system qualifies for a rebate and who files it. Some Austin Energy programs require a participating contractor. See AC installation and rebates.

Or let the line do the first step

Call and the line answers right away, day or night. You will be put through to a licensed local HVAC company, and you can still ask every question on this page before you agree to anything.

Common questions

How do I check an HVAC contractor's license in Texas?

Ask for the license number and look it up on the Texas Department of Licensing and Regulation website, tdlr.texas.gov.

How many quotes should I get?

For a repair, one clear diagnosis is often enough. For a replacement, two or three written quotes are worth the time.

Should I choose the cheapest quote?

Compare what each quote includes: sizing, permits, duct work, warranty and rebate paperwork. The cheapest quote often leaves something out.

What license class should an HVAC company have?

Texas issues Class A and Class B air conditioning contractor licenses, which differ in the size of systems covered. Either is fine for most homes; check that the license is active.
