Common Furnace Problems We Repair
Furnace Won’t Turn On
If your furnace does not start when the thermostat calls for heat, the problem could involve the thermostat, electrical supply, control board, ignition system, safety switch, or another furnace component.
Our technicians will diagnose the system to determine why the furnace isn’t starting and identify the right repair.
Furnace Is Blowing Cold Air
A furnace that runs but blows cool or cold air may have an ignition problem, a dirty flame sensor, a thermostat issue, restricted airflow, a gas supply problem, or another malfunction preventing the burners from operating properly.
Because several different problems can produce the same symptom, a technician should diagnose the furnace system issues before replacing parts.

Furnace Keeps Turning On and Off
When a furnace repeatedly starts and stops before your home reaches the thermostat setting, it is known as short cycling.
Restricted airflow, a dirty filter, thermostat problems, an overheating furnace, flame sensor problems, or a malfunctioning limit switch can all contribute to short cycling. Frequent cycling can also put unnecessary wear on furnace components.
Furnace Ignition or Flame Sensor Problems
Most modern furnaces use electronic ignition rather than a continuously burning pilot light. A failed igniter can prevent the burners from lighting, while a dirty or faulty flame sensor may cause the furnace to ignite and then shut down shortly afterward.
Older furnaces may use pilot-light systems that can develop their own ignition problems.
Furnace Blower Motor Problems
The blower moves heated air through your ductwork and into your home. If the blower motor fails or doesn’t operate correctly, the furnace may produce heat without distributing it effectively.
Blower problems can also cause unusual noises, weak airflow, overheating, or repeated furnace shutdowns.
Thermostat Problems
Sometimes the furnace isn’t the problem. Incorrect thermostat settings, wiring problems, failed sensors, dead batteries, or a malfunctioning thermostat can prevent the heating system from operating properly.
Checking the thermostat is part of diagnosing a furnace that will not start, will not stop running, or is not maintaining the desired temperature.
Strange Furnace Noises or Smells
Banging, rattling, squealing, grinding, or other unusual sounds can indicate loose components, blower problems, motor problems, or other mechanical issues.
A brief dusty smell when you first use a furnace for the season can be normal. However, don’t ignore persistent burning odors, electrical smells, or the smell of natural gas.
Cracked or Damaged Heat Exchanger
The heat exchanger separates combustion gases from the air circulated through your home. Damage to the heat exchanger can create a serious safety concern, including the potential for carbon monoxide exposure.
A qualified HVAC technician should evaluate any suspected heat exchanger problem. Depending on the furnace’s age and condition, replacing the furnace may be more appropriate than repairing it.

Signs Your Furnace May Need Repair
Not every furnace problem causes the system to stop working completely. Call for furnace service if you notice:
- The furnace runs, but your home does not get warm
- Cold or lukewarm air is coming from the vents
- The furnace repeatedly turns on and off
- The furnace makes unusual noises
- Airflow from the vents has become weak
- Some rooms remain noticeably colder than others
- The furnace does not respond properly to the thermostat
- You notice persistent burning or unusual odors
- Your heating costs increase without an obvious reason
A furnace problem is often easier to address before it results in a complete loss of heat.

Furnace Repair or Furnace Replacement?
Not every furnace problem means you need a new heating system. Many furnace problems can be repaired, particularly when the equipment has otherwise been operating reliably.
Replacement may make more sense when a furnace is older, requires frequent repairs, has a serious heat exchanger problem, or when the cost of repairing an aging system becomes difficult to justify.
Extreme Comfort will evaluate the condition of your furnace and explain your options so you can decide whether repairing or replacing the system makes more sense for your home.

Dallas Furnace Repair FAQs
Q: How much does furnace repair cost in Dallas?
A: The cost of furnace repair depends on what is causing the problem and which components, if any, need to be repaired or replaced. Extreme Comfort currently offers a $59 Furnace Repair Service Call to diagnose a non-working or malfunctioning furnace. Additional repairs and materials are quoted separately.
Q: Why is my furnace running but not heating my home?
A: A furnace that runs without producing enough heat may have an ignition problem, dirty flame sensor, thermostat issue, airflow restriction, blower problem, or another malfunction. A technician can test the system to determine the specific cause.
Q: Why is my furnace blowing cold air?
A: Cold air from the vents can be caused by thermostat settings, an ignition failure, flame sensor problems, restricted airflow, overheating, or other furnace issues. If the furnace keeps blowing cold air after you check the thermostat and filter, have a licensed HVAC technician inspect it.
Q: Why does my furnace keep turning on and off?
A: Frequent starting and stopping is called short cycling. Possible causes include restricted airflow, a dirty filter, thermostat problems, overheating, a faulty flame sensor, or a limit-switch problem.
Q: How do I know whether to repair or replace my furnace?
A: The decision depends on the furnace’s age, overall condition, repair history, efficiency, and the cost and severity of the current problem. A relatively minor repair may make sense on an otherwise reliable furnace, while a major repair on an older system may justify considering replacement.
Q: Do you offer same-day furnace repair?
A: Yes. Extreme Comfort offers same-day furnace repair when scheduling permits. Our regular service hours are 7 a.m. to 9 p.m., seven days a week.
Q: Do you repair both gas and electric furnaces?
A: Yes. Extreme Comfort diagnoses and repairs both gas and electric residential furnaces throughout the Dallas area.
Q: What should I do if I smell gas near my furnace?
A: If you smell natural gas or suspect a gas leak, leave the home and move to a safe location. Do not operate electrical switches or attempt to diagnose the furnace yourself. Contact your gas utility or emergency services as appropriate. After you address the immediate safety concern, an HVAC technician should inspect the heating system.
If a carbon monoxide alarm sounds, leave the home and follow the alarm manufacturer’s emergency instructions.
