Why is My Gas Furnace Blowing Cold Air?

Heating

As the seasons change, the more you feel the cool air blustering outside. And … inside your home? If your gas furnace is blowing cold air and adding a chill to your South Beloit and Belvidere home, it’s time to reach out to Fleming Heating & Air Conditioning Inc.. Once in a while an absence 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 a few of the more common reasons your gas furnace might be blowing cold air instead of making your home warm and cozy.

Your furnace might be overheating

If you haven’t had ongoing maintenance done on your gas furnace lately and you’ve neglected to replace your air filter, either could be the reason why your furnace is blowing cold air. A dirty air filter can stop air from flowing freely through your furnace. If that happens, the furnace could 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 attributed to something as simple as a pilot light that’s gone out. It’s possible, specifically with older furnaces, for a draft 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 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 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 ever reaches your vents.
