A free line for AC repair in Dallas
When the air conditioning quits in a Dallas July, you do not want to scroll through ads and leave voicemails. You want one number that answers and a real local company on the other end.
Dallas Air & Heating is that number. It is not an HVAC company. It has no technicians, no vans and no tools, and it never quotes a price. It is a free connection: you say whether it is cooling or heating, where you are and what the system is doing, and your call is transferred to an independent, locally owned heating and air conditioning company that works in your area. That company hears a short summary before it picks up, so you do not have to start over.
The line takes calls about home and business systems alike: central air that blows warm, a heat pump that will not keep up, a furnace that will not light, a unit that needs replacing, and the yearly tune-up that keeps all of it out of trouble.
How the call works
Four steps, and only the second one needs you. The full walkthrough is on the how it works page.
- 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.
Heating and cooling services the line covers
Each page explains what the job involves in North Texas, what a careful technician should do, and what to ask before you approve any work.
AC Repair
Warm air from the vents, a unit that hums but will not start, ice on the lines or water in the ceiling. What a proper diagnosis covers in Dallas heat and what to ask before you approve a repair.
Emergency AC Repair (24/7)
No cooling at night, on a weekend or in a heat wave. What to do while you wait, who is most at risk, and how after-hours calls are usually priced.
AC Installation and Replacement
When replacing beats repairing, why a load calculation matters more than the brand, and what a complete installation quote should list.
Furnace and Heating Repair
No heat on a cold North Texas morning, a furnace that short cycles or a heat pump stuck in defrost. Gas safety first, then what a technician checks.
HVAC Tune-Up and Maintenance
What a real spring or fall tune-up includes, what it does not, and the simple filter and drain habits that keep a system out of trouble.
Commercial HVAC
Rooftop units, offices, shops and restaurants. How commercial service differs from residential and what to ask a commercial HVAC contractor.
Why Dallas air conditioners work so hard
North Texas summers are long and hot, and they test every part of a cooling system. Weather records kept at DFW Airport by the Fort Worth office of the National Weather Service show triple digit heat usually showing up around the first of July and hanging on until late August. In 2011 the airport saw 71 such days, the most ever, and in the summer of 1980 it reached 100 or hotter 42 days in a row.
Weeks like that are when weak parts give out. A system that runs almost nonstop puts heavy wear on its compressor, fan motors and electrical parts, a dirty filter or coil chokes the airflow it needs, and a slow refrigerant leak finally shows up as warm air. That is why so many repair calls come in during the hottest stretch, and why a spring tune-up is worth the time.
Winter matters too. In February 2021 the Fort Worth weather office logged 139 hours in a row at or below freezing at DFW and a low of minus 2 degrees, and ERCOT, which runs most of the Texas grid, called for rotating power outages as generators went offline in the cold. Furnaces and heat pumps that seldom work hard in a mild Dallas winter suddenly had to. The furnace and heating repair page covers what to check and when to call.
Before you call, three safe checks
- Thermostat: set to Cool (or Heat), set a few degrees past room temperature, fan on Auto, fresh batteries if it uses them.
- Breaker: a tripped breaker for the indoor or outdoor unit can be switched back on one time. A second trip means a fault, so leave it off and call.
- Filter: a clogged filter can freeze the coil and stop cooling. Replace it if it is dirty.
Leave refrigerant, capacitors, wiring and anything gas to a licensed technician. Smell gas? Leave the house, then call 911 and your gas utility once you are outside. A carbon monoxide alarm means everyone goes outside before anyone calls 911.
Before anyone touches your system
The company you are put through to is independent, so you are the one who checks it. These questions take five minutes and protect you on any job.
What is your TDLR license number?
A Texas air conditioning contractor needs a state license from TDLR. The number takes a minute to check on TDLR's free license search, and the time to check it is before anyone starts work.
What exactly failed?
Ask for the diagnosis in plain words and the failed part named, so you know what you are paying for and can compare a second opinion.
What will it cost, in writing?
Get the service call charge and the repair price before work starts. For a replacement, ask for model numbers, the load calculation and the permit status.
Is repair an option?
A system that is old and failing may be worth replacing, but a working system does not have to be replaced because of refrigerant rule changes. The free refrigerant guide explains why.
Repair, replace or maintain
Most calls are repairs. Some systems are near the end of their life, and then the useful question is whether one more repair is worth it. When it is time to replace, the AC installation page explains sizing, efficiency ratings and what a complete quote lists. If you just want the system checked before summer or winter, see the HVAC tune-up page. Businesses with rooftop units can read about commercial HVAC.
Picking a company is its own decision. The guide to choosing an HVAC company in Dallas covers the license lookup, insurance, reviews and the red flags that should make you stop and get another quote. You are always free to do that, whether or not you call this line.
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.
