3 Reasons For Heater Blowing Cold Air In House
- The thermostat’s fan is set to ON. Check the fan setting on your thermostat, and if it’s set to ON, switch to AUTO. That way, your blower won’t run 24/7 and thus send cold air through the vents if the room reaches the desired temp.
- The furnace air filter is dirty. Dirty filters can clog the airflow inside the furnace and trigger a safety feature called the high limit switch. The burners will shut off if this happens, and it’s possible cold air could start to come through your vents. If it’s been a while since you’ve had your filters replaced, this is a good place to start troubleshooting.
- The furnace’s pilot light is off. Older furnace’s often have what’s called a standing pilot light.This is what lights the burners that heat the air flowing through your vents. If the pilot is off, the burners won’t be lit, so any air flowing through your house will not be heated. Relighting the pilot is not difficult, but varies from furnace to furnace. It’s also worth investigating why the pilot went out–as this could be a sign of a larger problem.
