In Farmers Branch, many older homes have gas furnaces in the attic or a hall closet, and the City spells out how their gas connections must be installed. Here’s what to check when the heat stops.
Farmers Branch heating trouble: first checks
- Status light. Count the blinks.
- Filter.
- 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.
- Gas valve. Find the shutoff near the furnace; don’t touch it if you smell gas.
Still no heat? Call 972-423-0012, 24/7.
Heating repairs Farmers Branch homes need
- Heat strips in townhome air handlers.
- Pressure switches.
- Blower motors.
- Igniters and flame sensors.
- Gas connectors and venting on older furnaces.

Farmers Branch homes and what their age means for your system
Farmers Branch has two very different housing stocks. About 31% of homes were built in the 1950s and 1960s, and about 40% since 2010, much of it apartments and townhomes. The Census puts the median at 2001, and about 43% of homes are detached houses.
The Census counts about 17,260 homes in Farmers Branch. Here’s how they break down by decade built:
| Built | Share of homes | What we often find |
|---|---|---|
| Before 1970 | About 31% | Farmers Branch’s 1950s and 1960s ranch homes. Equipment has been replaced several times; ducts and returns may be original. |
| 1970s–1990s | About 18% | 30 to 55 years old; usually on a second or third system. |
| 2000s | About 12% | Original systems are 15 to 25 years old. |
| 2010 and later | About 40% | Newer apartments, townhomes and houses, mostly R-410A or newer. |
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.
Farmers Branch’s replacement guide is specific about gas furnaces: a shutoff valve in the same room and within 6 feet of the unit, one appliance connector no longer than 6 feet that doesn’t pass through walls or floors, and venting and combustion air that may go back the way they were unless that would be hazardous. On older furnaces, those are exactly the items we check before relighting.
Farmers Branch permits for HVAC work
- All mechanical contractors performing work in the City must be registered with the City’s Building Inspection Department before starting any work.
- Farmers Branch says any HVAC replacement requires a permit to be applied for and approved before any work is done, unless the replacement or repair must be done in an emergency. In that case, the permit application is submitted the next business day.
- Permits and inspections: 972-919-2549.
- For a change-out, the installation and all associated work must be complete before the inspection. The City lists requirements for drains, pans, duct sealing, attic access, disconnects and gas connections.
Dallas Heating and Air Conditioning is registered with the City of Farmers Branch as a mechanical contractor. For a replacement, we pull the permit and schedule the inspection.
Townhomes and apartments built in Farmers Branch since 2010 often have electric air handlers or heat pumps instead of gas furnaces, so a no-heat call there is usually heat strips, a sequencer or the heat pump itself.
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.
