Why is My Gas Furnace Blowing Cold Air?

November 13, 2018

As the temps change, the more you feel the colder air gusting outside. And … in your home? If your gas furnace is blowing cold air and giving a chill to your Bend home, it’s time to call Tri County Climate Control LLC. Occasionally an absence of warm air from your gas furnace results in a major repair, but a lot of time it can be a small fix. Here are a few of the more common reasons your gas furnace could be blowing cold air instead of warming up your house.

Your furnace might be overheating

If you haven’t had routine maintenance performed on your gas furnace for some time and you’ve forgotten to change your air filter, either could be the reason why your furnace is blowing cold air. A dirty air filter can block air from flowing freely through your furnace. If this occurs, the furnace may overheat and shut down its burner.

Your pilot light may have gone out

It could be that 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, specifically with older models, for a breeze to smother a pilot light. Other factors when it comes to an extinguished pilot light are faulty gas valves or a faulty thermocouple.

Your furnace is dirty

Just as a dirty air filter can result in problems 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 struggle 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 might be losing a lot of heated air before it ever reaches your vents.
