University Park has homes from the 1920s next to rebuilds from last year, and an AC problem in each looks different. In older houses it’s often airflow; in new ones, zoning and controls. Here’s what to check first.
University Park AC: start with these
- Returns. Small or blocked return grilles starve older retrofitted systems.
- Filters. Multi-system homes have several; check each.
- Outdoor units. Is each fan spinning?
- 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.
- Which floor? In older homes, the second floor often struggles first; note which system controls it.
Still not cooling? Call 972-423-0012, 24/7.

University Park homes and what their age means for your system
University Park mixes some of the oldest homes in our service area with new rebuilds. About 31% of homes were built before 1960, and about 36% since 2000, so the Census median of 1990 hides a wide range. About 75% are detached houses.
The Census counts about 7,444 homes in University Park. Here’s how they break down by decade built:
| Built | Share of homes | What we often find |
|---|---|---|
| Before 1960 | About 31% | University Park’s original homes. Central air was added later, often with ducts squeezed into attics and walls never built for them. |
| 1960s–1970s | About 6% | About 50 to 65 years old; ducts and equipment have usually been redone. |
| 1980s–1990s | About 28% | Many are rebuilds on older lots, now on a second or third system. |
| 2000s | About 18% | Original systems are 15 to 25 years old. |
| 2010 and later | About 18% | Newer rebuilds, often with multiple systems and zoning. |
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 University Park’s pre-war and 1950s houses, central air was retrofitted long after construction. Ducts often run through tight attics, chases and closets, returns are small, and second floors are hard to cool. A bigger outdoor unit rarely fixes that; airflow does. In the newer rebuilds, the challenge is different: two or three systems, zoning, and equipment tucked into attics with long refrigerant runs. We look at the whole house before recommending a part or a system.
University Park permits for HVAC work
- The City’s permit FAQ says all plumbing, mechanical and electrical permits must be obtained by licensed contractors, and a mechanical permit may be needed for any addition or change to an existing system.
- Contractor registrations expire on the same annual date as the contractor’s state license. Registration is in person or through the City’s MyGov portal, where permits and inspections are handled.
- Community Development: Peek Service Center, 4420 Worcola, 214-987-5411.
- University Park’s code says that, except as otherwise provided, only an air conditioning and refrigeration contractor licensed by the State of Texas and registered with the City may obtain a permit for residential mechanical work.
Dallas Heating and Air Conditioning is registered with the City of University Park as a mechanical contractor. For a replacement, we pull the permit and schedule the inspection.
University Park’s FAQ says a mechanical permit may be needed for any addition or change to an existing system. Simple repairs usually don’t change the system, but if yours does, we tell you in the written price and pull the permit.
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.
