Why is My Gas Furnace Blowing Cold Air?

Heating

As the weather changes, the more you feel the colder air gusting outside. And … right inside your house? If your gas furnace is blowing cold air and adding a chill to your Grove City home, it’s time to call Air Quality Solutions. Occasionally an absence of warm air from your gas furnace calls for a big repair, but often it can be a simple fix. Here are several reasons your gas furnace may be blowing cold air instead of warming up your house.

Your furnace might be overheating

If you haven’t had ongoing maintenance performed on your gas furnace lately and you’ve neglected to replace your air filter, each could be the reason why your furnace is blowing colder air. A dirty air filter can prevent air from flowing freely through your furnace. If that happens, the furnace might overheat and force the burner to shut down.

Your pilot light may have gone out

Sometimes 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, specifically with older models, for a breeze to put out a pilot light. Other factors when it comes to an extinguished pilot light are damaged gas valves or a faulty thermocouple.

Your furnace is dirty

Just as a dirty air filter can result in issues for your gas furnace, so can other furnace components if they aren’t correctly cleaned. A dirty gas burner or flame sensor could cause your furnace to battle to stay lit and not be able to bring warmth to your home.

Your ducts may not be properly sealed

When ducts are correctly sealed or if they have any cracks or holes in them, you might be losing a lot of heated air before it even reaches the vents throughout the home.
