Why is My Gas Furnace Blowing Cold Air?

As the weather changes, the more you feel the cool air gusting outside. And … inside your home? If your gas furnace is blowing cold air and adding a chill to your Perry home, it’s time to reach out to Gillman Heating and Air. Sometimes the loss of warm air from your gas furnace calls for a big repair, but often it can be an easy fix. Here are a few of the more common reasons your gas furnace may be blowing cold air instead of keeping your home toasty.

Your furnace might be overheating

If you haven’t had ongoing maintenance performed on your gas furnace for some time and you’ve overlooked changing your air filter, either could be the reason why your furnace is blowing cool air. A dirty air filter can block air from flowing freely through your furnace. When this happens, the furnace might overheat and cause the burner to shut down.

Your pilot light may have gone out

It’s probable a lack of warm air from your gas furnace can be related to something as simple as a pilot light that’s gone out. It’s possible, particularly with older furnaces, for a draft to smother a pilot light. Other causes of an extinguished pilot light are defective gas valves or a faulty thermocouple.

Your furnace is dirty

Just as a dirty air filter can mean issues for your gas furnace, so can other furnace components if they aren’t appropriately cleaned. A dirty gas burner or flame sensor could cause your furnace to fight to stay lit and leave you in the cold.

Your ducts may not be properly sealed

If your ducts aren’t properly sealed or if they have any cracks or holes in them, you may be losing a lot of heated air before it even reaches the vents throughout the home.
