If your furnace is blowing cold air, this may be due to a malfunctioning pilot light. We recommend either checking the light or calling a professional to perform an HVAC repair project.
The pilot light is engineered to activate the burners and heating process. Without a functioning pilot light, the furnace will be unable to produce heat. To re-light the pilot light, you will need to find the pilot assembly and reset switch. The switch is usually located near the bottom of the furnace. Once you find the reset switch, move it to the off position to turn off the gas. Wait a couple of minutes prior to moving the reset switch to the on position to allow extra gas to exit from the chamber.
Move the reset switch to Pilot mode to allow gas to be sent to the pilot light. Next, press the reset button on your furnace and hold a match in front of the pilot light to confirm it is receiving gas. If you are able to produce a flame, release the reset button. Your furnace will now be operating properly. If the furnace is still blowing cold air, this may be an indicator of issues with the flame detector, air filter, gas supply, condensate lines, or ductwork.
