What Austin AC Service is
Austin AC Service is a free phone line for air conditioning and heating in the Austin area. It started in 2026 and is a d/b/a of Dominion Digital Group.
When you call (737) 378-9016, an automated assistant answers, asks whether it is a cooling or heating problem, takes your name, number, location and a description of what is happening, and transfers you to an independent, locally owned HVAC company serving your part of the area. That company hears a short summary before it picks up. If it cannot answer, your details are passed along for a call back.
What it is not
It is worth being plain about this, because a lot of sites blur it. Austin AC Service is not an HVAC company. It has no technicians and no trucks, and it holds no license. It does not diagnose, quote, schedule, supervise or guarantee any work, and it never charges the people who call. The company you are connected with does all of that and answers to you directly.
What you can count on
- The line answers 24 hours a day, 7 days a week
- Calling and being connected costs you nothing
- Every company it connects callers with holds an active TDLR ACR contractor license
What the line will never claim
- That it repairs, installs or inspects anything
- Reviews, ratings, awards or job counts it does not have
- Prices, response times or guarantees on someone else's work
How the line is paid
The independent HVAC companies the line connects callers with may pay Austin AC Service a referral fee. That is the whole business model. You are never billed by the line, and the line does not set or see the price the company quotes you.
Because of that arrangement, you should treat the company you are put through to the way you would treat any contractor you found yourself: check the license, get the diagnosis and price in writing, and ask whether repair is an option before replacement is quoted.
Why the site reads the way it does
Most of this website is not about the line at all. It is about Austin heating and cooling: what triple-digit summers and occasional hard freezes do to equipment, what the 2025 refrigerant change actually requires, how Austin Energy rebates and the City's ECAD audit work, and what a careful technician checks. Every page names its sources so you can check them. The aim is that you know enough to ask good questions, whoever you hire.
The free guide, The Refrigerant Changeover by Maurice Johnson, goes deeper on the refrigerant change and is a straight PDF download.
Check any license yourself. Texas air conditioning and refrigeration contractors are licensed by the Texas Department of Licensing and Regulation. Ask for the license number and look it up at tdlr.texas.gov (opens in a new tab).
