Why is My Gas Furnace Blowing Cold Air?

Heating

As the weather changes, the more you feel the cooler air gusting outside. And … inside your home? If your gas furnace is blowing cold air and giving a chill to your Zelienople home, it’s time to contact Knoechel Heating Company. Sometimes the loss of warm air from your gas furnace calls for a major repair, but often it can be an easy 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 could be overheating

If you haven’t had regular maintenance done on your gas furnace for some time and you’ve neglected to replace your air filter, either could signal why your furnace is blowing colder air. A dirty air filter can block air from flowing freely through your furnace. When this happens, the furnace might overheat and cause 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, especially with older models, for a breeze to smother 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 cause 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 not be able to bring warmth to your home.

Your ducts may not be properly sealed

When ducts are correctly sealed or if they have any cracks or holes in them, you could be losing a lot of heated air before it even reaches the vents throughout the home.
