Why Is My Furnace Blowing Cold Air?
Your furnace could be functioning well, but the air that comes from the vents is cold. A non-functional heater can be frustrating, especially during the cold months. Several reasons can cause your furnace to blow cold air. Here are some possible reasons and what to do about them.
Overheated Furnace
An overheated furnace usually happens when you don’t change the air filters, and it can result in cold air blowing from a furnace. The compromised airflow causes the furnace to overheat, shutting down its burner. You can try changing your air filters and restarting your furnace. If that doesn’t work, consider calling a professional to diagnose the issue.
Thermostat Issues
Your home is probably not as warm as the temperature you set, or the air coming out of the vents is cold. It could be that the heater doesn’t blow hot air even though the fan is running as it should. Consequently, the air that blows out of your vents when the heater is not running will feel cold. Check the thermostat setting to ensure that it is set to auto.
Empty Oil Tank
You are probably out of fuel if you use an oil-fired furnace, and it blows out cold air. In that case, your furnace keeps circulating cold air even if the burners don’t light and produce heat. You may need to refill your oil tank to enjoy a warm house.
Extinguished Pilot Light
If your home has an older furnace with a continuous pilot light, cold air blowing from the unit could be due to a faulty pilot. A pilot light may go out because of a gust of air originating from working near your furnace. You can try relighting the pilot on your own or hire a professional to help you.
