AC Repair in Carrollton, TX

Most Carrollton homes were built in the 1970s through the 1990s, and the City requires a permit even for some mechanical repairs. Before you call, a few checks can tell you whether it’s a simple fix. Here’s where to start.

Carrollton AC checklist before you call

• Drain line. Many attic units have a float switch; a backed-up drain shuts the AC off.
• Filter. Change it, then give the system time to recover.
• Outdoor unit. Is the fan spinning? Are the coil fins packed with leaves, lint or grass?
• Power. If the whole house is dark, report the outage to your electric delivery company (it’s on your bill) before you call an HVAC company. Some systems wait before restarting after power returns, so give it a little time.
• Thermostat batteries and mode. A dead thermostat looks like a dead AC.

Still not cooling? Call 972-423-0012 any time.

What usually breaks on Carrollton AC systems

• Condensate drain clogs on attic units.
• Coil leaks on 15- to 25-year-old systems.
• Contactors pitted from years of cycling.
• Compressors on aging units, which is usually a repair-or-replace decision.
• Capacitors, especially after long stretches of summer heat.

See why your AC isn’t blowing cold air and signs your AC needs repairs.

Carrollton homes and what their age means for your system

Carrollton’s housing peaked in the 1970s and 1980s. The Census puts the median home at 1988, and about 42% of homes heat with utility gas.

The Census counts about 54,365 homes in Carrollton. Here’s how they break down by decade built:

The house’s age doesn’t tell you the system’s age. The data plate on the outdoor unit does, and it’s the first thing we read.

Carrollton’s CityServe portal shows permit history by property, including past mechanical permits. If you’re not sure when your system was last replaced, that record can tell you, and it’s worth checking before you decide between repair and replacement. The City also publishes a monthly permit report that lists each mechanical permit issued, with a short description of the work, such as an HVAC replacement and the size and type of system installed.

Carrollton permits for HVAC work

• Mechanical work is a single-trade permit applied for through the CityServe portal.
• Every contractor must be registered with the City, with a copy of its state license on file. Permits aren’t issued until all contractors are registered, registration renews every year, and an expired registration blocks further inspections.
• Building Inspection: 972-466-3225.
• The City of Carrollton requires permits for repairs or replacement of mechanical systems. General maintenance doesn’t need a permit. Mechanical/HVAC is on the City’s list of residential work that requires one.

Dallas Heating and Air Conditioning is registered with the City of Carrollton as a mechanical contractor. For a replacement, we pull the permit and schedule the inspection.

Because Carrollton requires permits for repairs to mechanical systems, not just replacements, we’ll tell you in the written price whether your repair needs one. General maintenance, such as a filter change or cleaning, doesn’t.

Refrigerant and efficiency rules that affect your decision

R-22. The EPA ended the manufacture of new R-22 equipment in 2010 and the production and import of R-22 itself on January 1, 2020. An R-22 system can keep running, but it can only be recharged with recovered or reclaimed R-22. A large leak on an R-22 unit is often the point where replacement makes more sense than repair.

SEER2. Since January 1, 2023, Department of Energy rules require new split-system central air conditioners installed in the Southeast region, which includes Texas, to meet at least 14.3 SEER2 under 45,000 Btu/h and 13.8 SEER2 at 45,000 Btu/h and up. New split heat pumps nationwide must meet 14.3 SEER2. See SEER vs. SEER2.

New refrigerants. Under the EPA’s AIM Act rules, new home air conditioners and heat pumps are moving to refrigerants with lower global warming potential, such as R-454B and R-32. Read what the R-410A phase-out means.

How a Carrollton repair visit works

1. You call. We answer 24/7 and set a time that works for you.
2. Diagnosis. A NATE-certified technician checks the thermostat, electrical, airflow, refrigerant and drain, and finds the cause.
3. Written price. You get upfront written pricing before any work starts. If replacement makes more sense, we show you both options.
4. Permit if needed. If the repair is one Carrollton requires a permit for, we pull it.
5. Repair and test. We fix it, then check the temperature drop across the coil and the drain.

Call right away if

• A burning or electrical smell from the indoor or outdoor unit
• Water coming through a ceiling below an attic unit
• An AC that’s off in high heat with an infant, an older adult or someone with a medical condition in the house
• A breaker that trips again right after you reset it

Upfront written pricing before any work starts

• If we find more than one problem, each is listed separately so you can decide.
• If replacement makes more sense than repair, you get both options side by side.

• What the written price covers: the diagnosis, the part or repair, and any permit the City requires.
