About 45% of Arlington homes were built in the 1970s and 1980s, so many heating systems there have been replaced at least once, and some are older than the air conditioner they’re paired with. When the heat stops, safety comes first, then a few simple checks before you call.
No heat in Arlington? Check these before you call
- Power. Even a gas furnace needs electricity for its blower and controls. Oncor delivers electricity in Arlington. If the whole house is dark, check Oncor’s outage map or report it at 888-313-4747 before you call an HVAC company. Your system can’t run without power, and some systems wait before restarting after power returns, so give it a little time before you assume it’s broken.
- Gas smell. Atmos Energy delivers natural gas in Arlington. If you smell gas, leave the house first, then call Atmos Energy at 866-322-8667 or 911 from outside. Don’t touch the thermostat or light switches on the way out.
- Furnace door. Most furnaces won’t run if the front panel isn’t fully closed.
- Furnace switch and breaker. The switch near the furnace looks like a light switch and is easy to bump off.
- Filter. A clogged filter can overheat a furnace and trip its high-limit switch.
- Thermostat. Set to Heat, and above the room temperature.
Still cold? Call 972-423-0012, 24/7.
Heating repairs we handle
- Thermostats: wiring and settings, especially after a thermostat swap.
- Short cycling: a furnace that starts and stops over and over. See furnace short cycling.
- Electric furnaces and air handlers: heat strips, sequencers and blower motors.
- Heat pumps: reversing valves, defrost controls and backup heat strips.
- Gas furnaces: igniters, flame sensors, pressure switches, inducer motors, limit switches and control boards.

Arlington homes and what their age means for your system
Arlington’s homes skew older than many DFW suburbs. Census data puts the median Arlington home at 1986, and more than half were built before 1990, which means plenty of attic ductwork that’s 35 years old or more.
The Census counts about 153,137 homes in Arlington. Here’s how they break down by decade built, and what that usually means for the HVAC system inside:
| Built | Share of homes | What we often find |
|---|---|---|
| 1950s–1960s | About 14% | 60 years or older. Many were built before central air was standard, so the ducts and equipment location were added or reworked later. |
| 1970s | About 19% | About 50 years old. Original ductwork is common unless it was replaced, and leaky duct joints in a hot attic cost cooling. |
| 1980s | About 26% | Arlington’s biggest decade. Most have replaced the outdoor unit at least once, but the indoor coil, furnace and attic ducts are often older than the condenser. |
| 1990s–2000s | About 32% | Many systems from this period ran on R-22 and are due, or past due, for replacement. |
The house’s age doesn’t tell you the system’s age. The data plate on the outdoor unit shows its model, serial number and refrigerant type, and that’s the first thing we read on a visit.
Mismatched equipment is one of the most common problems we find in older Arlington homes: a newer outdoor unit paired with an original indoor coil or furnace. The system runs, but it may never cool the way it should. On a repair visit, we’ll tell you if that’s what’s going on.
Arlington permits for HVAC work
- Inspections are required before work is covered up and when the project is complete. Replacing a minor part that doesn’t change the equipment’s approval is exempt.
- Every Arlington permit is applied for online at ArlingtonPermits.com, and trade work must be done by a person licensed in that trade.
- If mechanical is the only trade involved, it’s a stand-alone Mechanical Permit (MP). If the job also needs electrical or plumbing work, the City requires a remodel permit instead.
- The City of Arlington lists HVAC replacement as work that requires a permit.
Dallas Heating and Air Conditioning is registered with the City of Arlington as a mechanical contractor. For a replacement, we pull the permit and schedule the inspection, so you don’t have to.
Refrigerant and efficiency rules that affect your decision
R-22. Many air conditioners installed before 2010 use R-22. The EPA ended its production and import on January 1, 2020. An R-22 system can keep running, but it can only be recharged with recovered or reclaimed R-22, so a big leak on an old 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. If your heating is a heat pump, the same rules apply, because it’s also your air conditioner. A failed heat pump means losing both heating and cooling. See heat pump repair.
