AC Repair in the Dallas-Fort Worth Metroplex

The A/C Techs Air & Heat LLC is a family-owned HVAC repair company serving homeowners across the Dallas-Fort Worth metroplex. When your AC stops cooling, we arrive fast, diagnose the real problem, and explain your options in plain English — no pressure, no upsells, no surprises on the final bill.

What Does AC Repair Typically Cost in Dallas?

Typical AC repair costs in the DFW area fall into three tiers. Minor repairs — replacing a capacitor, a contactor, a fuse, or a thermostat — generally run $75 to $250. Mid-tier repairs such as refrigerant leak searches, evaporator coil cleaning, or blower motor replacement typically cost $300 to $800. Major repairs like a compressor replacement or coil replacement can run $1,200 to $2,500 or more, depending on system size and refrigerant type.

A standard diagnostic service call is $85 to $150. We credit the diagnostic fee toward the repair if you have us do the work, and we always provide a written estimate before we start.

Why Is My AC Blowing Warm Air?

A central AC that's blowing warm air is usually caused by one of six problems:

• Dirty air filter — chokes airflow and can cause the evaporator coil to freeze.
• Thermostat issue — wrong setting, dead batteries, or failed unit.
• Refrigerant leak — most common on systems over 8 years old.
• Clogged condensate drain — on many modern systems, a safety switch shuts the unit off when the drain backs up.
• Failing capacitor or contactor — the outside unit runs but the compressor doesn't engage.
• Frozen evaporator coil — the result of low refrigerant or restricted airflow.

Start by checking your filter and thermostat. If those look fine, shut the system off and call us — running an AC low on refrigerant or with a frozen coil can cause expensive secondary damage.

How Long Does an AC Repair Take?

Most residential AC repairs are completed the same day. Typical repair times in our service area:

• Thermostat replacement — 30 minutes to 1 hour
• Capacitor or contactor replacement — 30 minutes to 1 hour
• Refrigerant recharge (no leak) — 1 to 2 hours
• Refrigerant leak repair — 2 to 6 hours, depending on leak location
• Blower motor replacement — 2 to 4 hours
• Evaporator coil replacement — 4 to 8 hours
• Compressor replacement — 4 to 8 hours (often a full-day job)

Should I Repair or Replace My AC?

A useful rule of thumb HVAC contractors call the "5,000 rule": multiply your system's age by the repair cost. If the number is over $5,000, replacement usually makes more financial sense than repair. For example, a 12-year-old unit needing a $500 repair scores 6,000 — replacement territory.

We also recommend leaning toward replacement when:

• The system is more than 10–15 years old and needs a major repair
• The unit uses R-22 refrigerant (phased out in the U.S. in 2020 — refrigerant costs have tripled)
• You've had more than two repairs in the last two summers
• Your energy bills are rising faster than your neighbors'

If replacement is the smarter move, we'll tell you honestly — and if your current system still has good years left, we'll say that too.

Do You Repair All AC Brands?

Yes. Our technicians service every major residential HVAC brand sold in Texas, including Trane, Carrier, Lennox, Rheem, Bryant, Goodman, American Standard, York, Amana, and Ruud, along with less common brands like Mitsubishi ductless and Heil. Texas heat is hard on every brand — the key is whether the equipment has been properly sized, installed, and maintained, not the badge on the side.

How Soon Can You Come Out?

Under normal demand we offer same-day service across the DFW metroplex, often within a few hours of your call. During the summer peak (June through September) and winter cold snaps, response times can stretch to 12–24 hours because every HVAC company in town is booked solid. We stay in touch so you always know where you are in our queue, and we prioritize households with vulnerable occupants, no heat, or no cooling above 85°F.
