Why is My Gas Furnace Blowing Cold Air?

As the weather changes, the more you feel the cooler air blowing outside. And … in your home? If your gas furnace is blowing cold air and adding a chill to your Omaha home, it’s time to reach out to The Frazier Company. Once in a while an absence of warm air from your gas furnace calls for a major repair, but many times it can be a small fix. Here are several reasons your gas furnace may be blowing cold air instead of warming up your house.

Your furnace may be overheating

If you haven’t had routine maintenance done on your gas furnace lately and you’ve neglected to replace your air filter, each 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 could 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, particularly with older models, for a draft to extinguish 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 cause issues for your gas furnace, so can other furnace components if they aren’t properly cleaned. A dirty gas burner or flame sensor could cause your furnace to battle to stay lit and reduce the warmth inside your house.

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.
