Why is My Gas Furnace Blowing Cold Air?

As the weather changes, the more you feel the cool air blowing outside. And … inside your home? If your gas furnace is blowing cold air and putting a chill to your Newton home, it’s time to call Brookwood Inc. Once in a while the loss of warm air from your gas furnace calls for a large repair, but often it can be an easy 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 done on your gas furnace lately and you’ve neglected to replace your air filter, both could indicate why your furnace is blowing cold air. A dirty air filter can prevent air from flowing freely through your furnace. If that happens, 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 attributed to something as simple as a pilot light that’s gone out. It’s possible, specifically with older models, for a gust of air to extinguish a pilot light. Other causes of an extinguished pilot light are faulty gas valves or a faulty thermocouple.

Your furnace is dirty

Just as a dirty air filter can mean issues 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 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 can get to the vents.
