About 41% of Mesquite homes heat with gas, according to the Census. When a Mesquite furnace stops, safety comes first, then a few checks you can make yourself.
Furnace out in Mesquite? Check these first
- Blinking light. Most furnaces have a status light that blinks a code. Count the blinks; it helps the diagnosis.
- Filter. A clogged filter can trip the high-limit switch.
- Furnace switch. A switch near the furnace that looks like a light switch.
- Thermostat. Heat mode, set above room temperature.
- Gas smell. If you smell gas, leave the house first, then call 911 and Atmos Energy’s emergency line, 866-322-8667, from outside. Don’t touch the thermostat or light switches on the way out.
Still no heat? Call 972-423-0012.

Mesquite homes and what their age means for your system
Mesquite is an established city. The Census puts the median Mesquite home at 1983, and about 7 in 10 were built before 1990. About 41% of Mesquite homes heat with utility gas, so gas furnaces are a big share of heating calls.
The Census counts about 53,953 homes in Mesquite. Here’s how they break down by decade built:
| Built | Share of homes | What we often find |
|---|---|---|
| Before 1970 | About 24% | 55 years or older. Central air was often added later; ducts may be undersized for today’s equipment. |
| 1970s | About 16% | About 50 years old. Original attic ductwork is common unless replaced. |
| 1980s | About 29% | Mesquite’s biggest decade. Most are on their second or third outdoor unit. |
| 1990s | About 16% | About 30 years old; many second systems from the 2000s ran on R-22. |
| 2000 and later | About 16% | Newer homes, mostly R-410A equipment. |
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.
Mesquite’s inspection rules require that duct sealant be an approved material under the state and local mechanical codes, and the City inspects mechanical work at the duct rough-in and at the final. In older homes, duct connections at the plenum and the boots are where we most often find leaks.
Mesquite permits for HVAC work
- City code requires mechanical contractors working in Mesquite to register with the City. Building Inspection: 972-216-6212 or 972-216-6213.
- The City’s mechanical inspections are a duct rough-in and a mechanical final. Inspection tags are left in the permit pouch at the job.
- Mechanical installations must be installed and permitted by a contractor licensed by the State of Texas. A homeowner who lives in the house may apply for a permit to do the work themselves.
- The City of Mesquite’s residential fee schedule lists a Mechanical permit that includes condenser and furnace replacement.
Dallas Heating and Air Conditioning is registered with the City of Mesquite as a mechanical contractor. For a replacement, we pull the permit and schedule the inspection.
In many Mesquite homes from the 1960s through the 1980s, the furnace is in a hall closet or the attic and the AC coil sits on top of it. A furnace problem can affect cooling, and a clogged coil can affect heating airflow.
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.
