Why is My Gas Furnace Blowing Cold Air?

As the weather changes, the more you feel the cooler air gusting outside. And … inside your home? If your gas furnace is blowing cold air and giving 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 a simple fix. Here are a few of the more common reasons your gas furnace might 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, both could be the reason why your furnace is blowing cool air. A dirty air filter can block air from flowing freely through your furnace. If this occurs, the furnace might overheat and shut down its burner.

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, especially 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 cause 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 not be able to bring warmth to your home.

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.
