AC Repair in Prosper, TX

The median Prosper home was built in 2014, so most AC calls here aren’t worn-out systems. They’re drains, capacitors, leaks and setup problems in big two-story homes. Here’s what to check first.

Prosper AC checklist

• 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.
• Breakers. One for each system; reset once.
• Mini-split? Check its remote mode and clean its filters.
• Drain line. A backed-up drain or tripped float switch is common on attic units.
• Which system? Find the thermostat that controls the warm area; many Prosper homes have two or three.

Still not cooling? Call 972-423-0012, 24/7.

Prosper homes and what their age means for your system

Prosper is the newest town we serve. The Census puts the median home at 2014, and about one in five homes has gone up since 2020. About 89% are detached houses, many of them large two-story homes.

The Census counts about 11,921 homes in Prosper. 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 a Prosper home built in the 2010s, most AC and heating problems are not old age. They’re clogged condensate drains, failed capacitors, refrigerant leaks at a coil or a flare fitting, and thermostats or zoning set up wrong at move-in. Many larger homes have two or three systems, and some have a mini-split for a garage, office or media room. Because Prosper’s HOAs and deed restrictions may limit where equipment goes, the Town says to check them before you apply for a permit; the Town doesn’t enforce them, but they may supersede its rules.

Prosper permits for HVAC work

• Most permits expire 180 days from issuance or from the last approved inspection, whichever is most recent.
• You can find registered contractors through the Town’s CSS Portal by contractor type, including mechanical, or by calling Building Inspections at 972-346-3502.
• A hired contractor must obtain the permit, because contractors are required to be registered with the Town and are responsible for making sure the work meets Town ordinance and code. The Town says to always ask to see the permit before work begins.
• The Town of Prosper requires a permit for HVAC installations, including replacement of air handlers and condensers and installation of mini-split systems.

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

If a repair turns into replacing the condenser or air handler, Prosper requires a permit. The Town says to always ask to see it before work begins, and we’ll show you ours.

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 Prosper 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 Prosper 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.
