Why is My Gas Furnace Blowing Cold Air?

Heating

As the temps change, the more you feel the colder air gusting outside. And … inside your home? If your gas furnace is blowing cold air and adding a chill to your Genoa home, it’s time to reach out to Assured Appliance and Heating & Air. Sometimes a lack of warm air from your gas furnace results in a big repair, but a lot of time it can be a small fix. Here are several reasons your gas furnace might 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, either 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 this occurs, the furnace might overheat and force the burner to shut down.

Your pilot light may have gone out

It could be that a lack of warm air from your gas furnace can be attributed to something as simple as a pilot light that’s gone out. It’s possible, especially with older furnaces, for a gust of air to extinguish a pilot light. Other causes of an extinguished pilot light are faulty gas valves or a faulty thermocouple.

Your furnace is dirty

Just as a dirty air filter can cause problems 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 struggle 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 sealed properly or if they have any cracks or holes in them, you might be losing a lot of heated air before it ever reaches your vents.
