When the heat stops in University Park, the age of the house matters: an old attic furnace with a long flue needs different checks than a new zoned system. Here’s what to look at, and when to leave first.
University Park heating: start with these
- CO alarm. If it sounds, get out and call 911.
- Which zone? Check the thermostat for the cold area.
- Furnace door and switch.
- 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.
- Gas smell. If you smell gas, leave the house first, then call 911 and your gas utility from outside. Don’t touch the thermostat or light switches on the way out.
Still cold? Call 972-423-0012 any hour.

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.
Many older University Park homes have a gas furnace in an attic or a hall closet, with a vent that runs up through the house. On those, we look at the flue, the combustion air and the gas connection on every visit. In newer rebuilds with several systems, a cold room is often one zone or one damper, so we test each system and zone separately before replacing parts.
University Park permits for HVAC work
- 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.
- 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.
- 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.
- Community Development: Peek Service Center, 4420 Worcola, 214-987-5411.
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.
If your University Park furnace is in a closet or attic in an older house, carbon monoxide alarms near sleeping areas are worth having. Any CO alarm is a reason to leave first and call 911.
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.
Heat pumps. A heat pump is also your air conditioner, so the same rules apply, and a failed heat pump can take out heating and cooling at once. See heat pump repair.
