Why is My Gas Furnace Blowing Cold Air?

Heating

As the weather changes, the more you feel the cool air blustering outside. And … in your home? If your gas furnace is blowing cold air and putting a chill to your Hudsonville home, it’s time to reach out to West Michigan Heating & Air Conditioning Services. Occasionally the loss of warm air from your gas furnace results in a big repair, but many times it can be a simple fix. Here are a few of the more common reasons your gas furnace might be blowing cold air instead of keeping your home toasty.

Your furnace may be overheating

If you haven’t had ongoing maintenance performed on your gas furnace recently and you’ve overlooked changing your air filter, both could be the reason why your furnace is blowing colder air. A dirty air filter can stop 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

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 models, for a draft to smother a pilot light. Other causes of 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 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 may be losing a lot of heated air before it even reaches the vents throughout the home.
