AC Repair in Farmers Branch, TX

Farmers Branch has 1950s ranch homes and brand-new townhomes, and the City publishes its own checklist for HVAC replacements. Here’s what to check before you call about an AC problem.

Farmers Branch AC trouble: first checks

• Thermostat. Cool mode, setpoint below room temperature.
• Disconnect and breaker at the outdoor unit; reset once.
• 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.
• Float switch. Water in the pan under the coil shuts the AC off on many units.
• Filter.

AC repairs Farmers Branch homes need

• Coil leaks on older systems.
• Undersized returns in 1950s and 1960s houses.
• Disconnects and wiring at the outdoor unit.
• Drain line clogs and float switch trips.
• Capacitors.

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

Farmers Branch homes and what their age means for your system

Farmers Branch has two very different housing stocks. About 31% of homes were built in the 1950s and 1960s, and about 40% since 2010, much of it apartments and townhomes. The Census puts the median at 2001, and about 43% of homes are detached houses.

The Census counts about 17,260 homes in Farmers Branch. 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.

In Farmers Branch’s 1950s and 1960s ranch houses, the AC usually sits on a slab outside with the furnace and coil in the attic or a hall closet. Returns tend to be small for today’s equipment, and the electrical feed to the outdoor unit may be older than the unit itself. In the newer townhomes and apartments, compact closet air handlers and long drain runs are the common issues. The City’s own HVAC replacement guide calls for a float switch on upflow and downflow units and for drains sloped at least 1/8 inch per foot, and we check both.

Farmers Branch permits for HVAC work

• For a change-out, the installation and all associated work must be complete before the inspection. The City lists requirements for drains, pans, duct sealing, attic access, disconnects and gas connections.
• Permits and inspections: 972-919-2549.
• Farmers Branch says any HVAC replacement requires a permit to be applied for and approved before any work is done, unless the replacement or repair must be done in an emergency. In that case, the permit application is submitted the next business day.
• All mechanical contractors performing work in the City must be registered with the City’s Building Inspection Department before starting any work.

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

If your AC fails and the fix is an emergency replacement, Farmers Branch lets the work go ahead and requires the permit application the next business day. We handle that paperwork.

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 Farmers Branch 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 Farmers Branch 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.
