Why is My Gas Furnace Blowing Cold Air?

November 13, 2018

As the temps change, the more you feel the cool air blowing outside. And … in your home? If your gas furnace is blowing cold air and putting a chill to your Westerville home, it’s time to call Uptown Heating & Cooling. Once in a while a lack of warm air from your gas furnace means a major repair, but many times it can be a small fix. Here are a few of the more common reasons your gas furnace may be blowing cold air instead of making your home warm and cozy.

Your furnace could be overheating

If you haven’t had routine maintenance done on your gas furnace lately and you’ve forgotten to change your air filter, both could indicate why your furnace is blowing cold air. A dirty air filter can stop air from flowing freely through your furnace. When this happens, the furnace might overheat and force the burner to shut down.

Your pilot light may have gone out

It’s probable a lack of warm air from your gas furnace can be related 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 reasons for 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 correctly 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 properly 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.
