Your Furnace Is Blowing Cold Air?
If your furnace is blowing cold air, this is a sign of an issue with the flame detector, gas supply, pilot light, air filter, or condensate lines.
Your furnace might be running just fine, but the air blowing out of your vents feels cold. We have found some of the possible answers.
1. Damaged Pilot Light
Check the pilot light on your gas system to ensure it’s working. We also recommend you follow the instruction kit to re-light the pilot.
2. Dirt on the Flame Detector
Furnaces without pilot lights rely on flame detectors. If your flame detector is covered in dust and dirt, your furnace will start blowing cold air due to a malfunction.
3. The Thermostat Set To On Instead Of Auto
Simple thermostat switch setting from On to the Auto will ensure the gas furnace in your home will only run during the usual heating process.
If none of these reasons answer why your furnace blows cold air, it is best to call our team and schedule an appointment.
