Calling about an air conditioner is easier when you know what to ask for. This page puts every AC service and heating service the line covers in one place, with a plain description of each and a link to the full page.
Dallas Air & Heating does not send technicians. Call (469) 649-7066, tell the automated assistant whether it is cooling or heating, where you are and what the system is doing, and you are put through to an independent HVAC company that works in your part of Dallas-Fort Worth. The descriptions below help you explain the problem in a sentence or two.
Which service do I need?
Start with what you notice. If more than one row fits, say so on the call.
| What you notice | Service that usually fits | Read first |
|---|---|---|
| Air from the vents is warm or barely cool | AC repair | AC repair |
| No cooling at night, on a weekend or in a heat wave, with someone at risk in the house | Emergency AC repair | Emergency AC repair |
| The system is old, keeps breaking or needs a major part | Repair quote, then a replacement quote to compare | AC installation and replacement |
| No heat, a furnace that will not light or a heat pump blowing cold | Furnace and heating repair | Furnace and heating repair |
| Everything works, but summer or winter is coming | Tune-up | HVAC tune-up |
| A rooftop unit, office, store or restaurant system | Commercial HVAC | Commercial HVAC |
| You smell gas or a carbon monoxide alarm sounds | Get out first, then call 911 and the gas utility | Gas safety |
Cooling
AC repair
The most common call. The system runs but blows warm air, the outdoor unit hums and will not start, ice forms on the copper lines, or water shows up where it should not. A good technician measures before replacing parts, names what failed and prices the fix before starting.
Emergency AC repair
The same work after hours, when heat is a health risk. That page covers who is most at risk in a Dallas heat wave, what to do while you wait, cooling centers, and how after-hours charges usually work.
AC installation and replacement
When repair no longer makes sense. Sizing with a load calculation, efficiency ratings, the newer refrigerants, permits and what a complete written quote should list.
Heating
Furnace and heating repair
Gas furnaces, heat pumps and electric heat strips each fail in their own ways. The page starts with gas and carbon monoxide safety, then explains what a technician checks when the heat will not come on, and why a hard freeze like February 2021 tests systems that rarely work hard in a Dallas winter.
HVAC tune-up and maintenance
A spring check before cooling season and a fall check before heating season. The page lists what a real tune-up includes, what it does not, and the filter and drain habits that prevent most problems.
Every service page
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.
Businesses
Shops, offices, restaurants and warehouses usually run packaged rooftop units, and a breakdown costs them customers as well as comfort. The commercial HVAC page explains how commercial service differs from residential work, the Texas license classes that cover larger systems, and what to ask a commercial contractor.
Choosing who does the work
Whatever the service, the company you are put through to is independent of the line. Before you approve any work, read the guide to choosing an HVAC company in Dallas, and check the license yourself.
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.
