What Dallas Air & Heating is
Dallas Air & Heating is a free phone line for air conditioning and heating across the Dallas-Fort Worth area. It was started in 2026 and is run by Dominion Digital Group, which operates it under the Dallas Air & Heating name.
When you call (469) 649-7066, an automated assistant answers, asks whether it is a cooling or heating problem, takes your name, callback number, city or ZIP and a description of what is going on, and transfers you to an independent, locally owned heating and air conditioning company that serves your area. That company hears a short summary before it picks up. If it cannot answer, your details go to it for a call back.

Why a free line exists at all
Finding help when the AC dies on a July evening usually means a page of ads, companies that do not work on your side of the metroplex, and a string of voicemails. The heat does not wait while you sort through them. A single number that always answers and routes you by location cuts that hunt down to one call.
It also keeps the important decisions with you. You still hear the diagnosis and the price straight from the company. You can still say no. And you can still check the company's license yourself before anyone climbs into the attic.
What it is not
A lot of websites blur this line, so here it is plainly. Dallas Air & Heating is not an HVAC company. It has no technicians, no trucks and no license. It does not diagnose, quote, schedule, supervise or stand behind any work. The company you are connected with does all of that and answers to you directly.
What you can count on
- The phone is answered 24 hours a day, 7 days a week
- Calling and being connected costs you nothing
- The referral fee arrangement is disclosed on every page
- This site explains how to check a TDLR license yourself
What the line will never claim
- That it repairs, installs or inspects anything
- Reviews, ratings, awards or job counts it does not have
- Prices or arrival times for someone else's work
- That any company is licensed or insured on its say-so
How the line makes money
The independent HVAC companies the line connects callers with may pay Dallas Air & Heating a referral fee. That is the entire business model. You are never billed by the line, and the line does not set, see or mark up the price the company quotes you.
Because of that arrangement, 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 the price in writing, and ask whether repair is an option before replacement comes up.
Who the line is for
Homeowners, renters checking on a landlord's system, and small business owners anywhere in Dallas-Fort Worth: Dallas itself, Collin County cities like Plano, Frisco, McKinney and Allen, Denton County towns like Lewisville, Flower Mound and Denton, and Tarrant County cities like Fort Worth and Arlington. The service areas page lists every city with its own page.
It is especially useful when time matters: a house that is getting hot with an older relative or a baby inside, a furnace that quits on a freezing morning, or water dripping from an attic unit. In any of those, one call does the searching for you.

Why most of this site is not about the line
Most pages here are about heating and cooling in North Texas: what long triple-digit stretches do to equipment, what the refrigerant change means for an older system, why so many DFW air handlers sit in hot attics, and what a careful technician checks. Pages that state facts list their sources so you can check them. The goal is simple: whoever you end up hiring, you should know enough to ask good questions.
The free guide to the refrigerant change by Maurice Johnson goes deeper on that one topic and is a straight PDF download on the free AC refrigerant guide page. To see exactly what happens on a call, read how the free line works.

Check the license yourself. In Texas, air conditioning and refrigeration contractors are licensed by the Texas Department of Licensing and Regulation (TDLR), and the license number belongs on the company's quotes and invoices. Ask for it and look it up with the TDLR license search (opens in a new tab) before work starts. It is also fair to ask for a certificate of insurance.
How this line works: Dallas Air & Heating is a free phone line, not an HVAC company. It answers your call and connects you with an independent local heating and air conditioning company, which inspects, quotes and does the work, and which you pay directly. The line holds no HVAC license and does not repair, install or schedule anything itself. Those companies may pay Dallas Air & Heating a referral fee. You never pay the line. How it works.
