AC Repair in Rockwall, TX

More than a third of Rockwall homes were built in the 2000s, so many AC systems here are original and 15 to 25 years old. Here’s what to check before you call, and when a repair needs a permit in Rockwall.

Rockwall AC: what to check first

• Filter.
• Thermostat. Cool mode, setpoint below room temperature.
• Drain. Water in the pan or a tripped float switch shuts the AC down.
• 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.
• Data plate. Note the outdoor unit’s year; many Rockwall units date from the 2000s.

Rockwall homes and what their age means for your system

Rockwall grew fastest in the 2000s, which built about 35% of its homes. The Census puts the median at 2003, and about 78% of homes are single-family detached houses.

The Census counts about 19,328 homes in Rockwall. 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.

Because so many Rockwall homes went up in the 2000s, a lot of original builder systems are now 15 to 25 years old. That’s when an outdoor unit or furnace failure turns into a replacement question. Rockwall draws a clear line here: repairing an AC unit, such as replacing a coil or contactor or adding refrigerant, doesn’t need a permit, but replacing the condensing unit or the heating unit does. Knowing which side of that line your job falls on helps you compare quotes.

Rockwall permits for HVAC work

• Repairs to air conditioning units, such as replacing the coil or contactors, or charging the unit with refrigerant, don’t require a permit. When the condensing unit or the heating unit is replaced, a permit must be obtained.
• A licensed HVAC contractor must get the permit and do the work. Texas allows homeowners to install a system on a home they own, live in and homestead through Rockwall Central Appraisal District, but recovering refrigerant takes a licensed contractor, and rental properties must use one.
• Contractors register through the City’s CityWorks portal, where inspections are also scheduled. Building Inspections: 972-771-7709.
• The City of Rockwall requires a permit for all HVAC installations.

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

In Rockwall, a coil replacement, a contactor or a refrigerant charge doesn’t need a permit, so most repairs can be done on the first visit once you approve the written price. If the condensing unit itself has to be replaced, Rockwall requires a permit first.

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 Rockwall 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 Rockwall 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
