Common Furnace Problems We Fix
A furnace that will not start, short cycles or blows cold air is more than uncomfortable. Some problems, like cracked heat exchangers or venting issues, can put your family at risk of carbon monoxide exposure. Our technicians can spot the warning signs and fix the root cause. Common problems include:
- Furnace blowing cold or lukewarm air
- Ignitor or flame sensor failure
- Pilot light or ignition problems on older furnaces
- Dirty filters restricting airflow
- Faulty or miscalibrated thermostats
- Leaky or disconnected ductwork
- Blocked flue pipes or venting
- Clogged condensate drains on high-efficiency furnaces
- Worn blower motors or inducer motors
- Furnace short cycling or tripping the limit switch
Whatever the issue, our technicians diagnose the problem, explain your options and either replace the damaged part or service the entire unit. We service gas and electric furnaces from all major brands.
24/7 Emergency Furnace Repair
Heating failures always seem to happen on the coldest night of the year. Southern Air offers 24/7 emergency response so you can get help nights, weekends and holidays. Our office is open Monday through Friday, 7 a.m. to 4 p.m., and our team is available around the clock for emergencies.
Safety tip: If you smell gas, leave your home immediately and call Atmos Energy or 911 from outside before calling us.
How Often Should You Have Your Furnace Serviced?
We recommend having your furnace professionally serviced at least once a year, ideally in the fall before the first cold front. Annual maintenance helps your furnace run efficiently, extends its lifespan and gives our technician a chance to check for safety issues like gas leaks, cracked heat exchangers and carbon monoxide risks.
A furnace tune-up typically includes:
- Inspecting the burners, ignitor and flame sensor
- Checking the heat exchanger for cracks or damage
- Testing safety controls and limit switches
- Checking gas pressure and venting
- Inspecting the blower motor and belts
- Replacing or checking the air filter
- Testing thermostat operation
Our Star Maintenance Agreement includes a heating visit each fall, a cooling visit each spring and priority service, so your whole system stays ready year-round.

Frequently Asked Questions About Furnace Repair
Why is my furnace blowing cold air?
Common causes include a dirty filter that triggered the high-limit switch, a failed ignitor or flame sensor, a thermostat set to “fan on” instead of “auto,” or a clogged condensate drain on a high-efficiency furnace. If changing your filter and checking the thermostat do not help, call a technician.
How long do furnaces last in North Texas?
Gas furnaces in North Texas often last 15 to 20 years with regular maintenance, since they run fewer months per year than furnaces in colder climates. Age, maintenance history and installation quality all affect lifespan.
Is furnace maintenance really necessary in Texas?
Yes. Even with mild winters, annual maintenance helps prevent breakdowns during cold snaps, improves efficiency and allows a technician to check for carbon monoxide and gas safety issues.
Do you repair heat pumps too?
Yes. Many North Texas homes heat with heat pumps or dual-fuel systems. Our technicians repair and maintain heat pumps, furnaces and air handlers from all major brands.
