Why is My Gas Furnace Blowing Cold Air?

As the seasons change, the more you feel the cool air gusting outside. And … right inside your house? If your gas furnace is blowing cold air and giving a chill to your Moline home, it’s time to reach out to Freed Heating & Air Conditioning. Occasionally an absence of warm air from your gas furnace calls for a big repair, but many times it can be a simple fix. Here are several 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 routine maintenance completed on your gas furnace for some time and you’ve forgotten to change your air filter, each could signal why your furnace is blowing colder air. A dirty air filter can prevent air from flowing freely through your furnace. When this happens, 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 attributed to something as simple as a pilot light that’s gone out. It’s possible, specifically with older furnaces, for a breeze to extinguish 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 challenges 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 leave you in the cold.

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 can get to the vents.
