How coverage works
The line has no trucks to dispatch and no office in any city. What it does is send your call to an independent company that works where you live.
When you call (469) 649-7066, the automated assistant asks for your city or ZIP code along with what the system is doing. The call is then transferred to an independent, locally owned heating and air conditioning company that serves your part of the metroplex. If that company cannot pick up, it gets your details to call you back.
The cities below have their own pages because many people there search for AC repair. Each page is written about that city: its electric and gas utilities, its permit rules for replacing a system, the age of its homes and the weather events that hit it. If your town is not listed, call anyway.

Cities with their own page
Grouped by county. A few cities spread across more than one county; they are listed where most people would look for them.
Collin County
- AC repair in McKinney: Collin County seat since the 1840s, grown from 21,283 residents in 1990 to 195,308 in 2020.
- AC repair in Frisco: Spans Collin and Denton counties, with power from CoServ or Oncor lines and gas from CoServ Gas or Atmos.
- AC repair in Plano: Grew from 17,872 people in 1970 to 222,030 by 2000, so many homes now have aging systems.
- AC repair in Allen: Collin County railroad town named in 1872, grown from 18,309 residents in 1990 to 104,627 in 2020.
Dallas County
- AC repair in Richardson: Postwar city split between Dallas and Collin counties, on Oncor lines, where HVAC contractors register with the city.
- AC repair in Garland: Many homes buy power from city-owned Garland Power & Light; the 2015 EF4 tornado struck its southeast side.
- AC repair in Mesquite: The Rodeo Capital of Texas, mostly 1960s to 1980s homes, where contractors register for a free city Professional License before pulling permits.
- AC repair in Irving: Home to Las Colinas and part of DFW Airport, where HVAC work needs its own mechanical permit.
Denton County
- AC repair in Carrollton: Spans three counties and nearly tripled in the 1970s, when much of its housing went up.
- AC repair in Lewisville: Grew up around Lewisville Lake, sits on Oncor or TNMP lines, and annexed Castle Hills in 2021.
- AC repair in Flower Mound: Mostly owner-occupied town between Grapevine and Lewisville lakes, built largely in the 1990s.
- AC repair in Denton: County seat, home to UNT and TWU, where many homes buy power from city-owned Denton Municipal Electric.
Tarrant County and the mid-cities
- AC repair in Fort Worth: A city of over one million where about half the homes predate 1980, beside fast-growing northern subdivisions.
- AC repair in Arlington: Tarrant County city that grew from 7,692 people in 1950 to about 402,000, hit by tornadoes in 2000 and 2012.
- AC repair in Grand Prairie: A 26 mile long city spanning Dallas, Tarrant and Ellis counties, from postwar streets to homes near Joe Pool Lake.
What changes from city to city
Who delivers your power
Across most of the metroplex, Oncor owns the poles and wires and you buy electricity from a retail provider you choose, so a power outage is reported to Oncor, not to the company on your bill. Some cities are different. Garland Power & Light serves much of Garland, Denton Municipal Electric serves much of Denton, and parts of Collin and Denton counties are on cooperative lines such as CoServ. Your bill tells you which one is yours, and it matters when you are deciding whether the AC broke or the power did.
Permits for a replacement
Replacing a system usually involves the city's building inspection office, and the rules and fees differ. Several cities also require HVAC contractors to register locally on top of the state license. The city pages say what each city's own site confirms; when in doubt, ask the company whether it will pull the permit.
How old the houses are
Older close-in suburbs have many homes from the 1950s to the 1970s, with ductwork and electrical service that newer equipment may outgrow. Fast-growing cities to the north have more homes from the 1990s onward. Age shapes what usually breaks and whether repair or replacement makes sense.

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.
- Call any hourAn automated assistant answers (469) 649-7066 and asks whether it is about cooling or heating.
- Describe the problemGive your name, a callback number, your city or ZIP and what the system is doing.
- Get put throughThe call goes to an independent, locally owned heating and air conditioning company, which hears a short summary before it picks up.
- Deal with them directlyThat company diagnoses, quotes, does the work and is paid by you. If it cannot answer, it gets your details to call back.
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.
