Why Is My Furnace Blowing Cold Air?
Why Is My Furnace Blowing Cold Air?
Dirty Air Filter
If the air filter in your furnace is dirty or clogged, it can restrict airflow and cause the furnace to overheat. This can trigger a safety feature that shuts off the burner and blows cold air instead. Regular maintenance will ensure your filter is replaced and stays clean year around.
Pilot Light or Ignition
If you have a gas furnace, the pilot light or ignition system may be malfunctioning. If the pilot light is out or the ignition system is not working correctly, the furnace will not be able to produce heat. We all know fire produces heat and without the pilot light on there is no fire.
A Faulty Thermocouple
A thermocouple is a safety device that detects whether the pilot light is lit. If the thermocouple is faulty, it may not detect the pilot light, and the furnace will not produce heat. Luckily, our certified techs can replace a faulty thermocouple in no time.
Malfunctioning Blowing Motor
The blower motor is responsible for distributing warm air throughout your home. If the blower motor is not working correctly, it may not be able to push warm air out of the furnace and into your home.
