Why is My Gas Furnace Blowing Cold Air?

As the seasons change, the more you feel the cool air gusting outside. And … inside your home? If your gas furnace is blowing cold air and putting a chill to your Gresham home, it’s time to reach out to Honke Heating & AC. Occasionally a lack of warm air from your gas furnace calls for a big repair, but often it can be a simple fix. Here are some of the main 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 ongoing maintenance completed on your gas furnace recently and you’ve forgotten to change your air filter, both could indicate 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 may 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 credited to something as simple as a pilot light that’s gone out. It’s possible, especially with older models, for a gust of air to extinguish 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 mean problems 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

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 even reaches the vents throughout the home.
