Why is My Gas Furnace Blowing Cold Air?

As the weather changes, the more you feel the cool air gusting outside. And … right inside your house? If your gas furnace is blowing cold air and giving a chill to your Bishop home, it’s time to reach out to Bishop Heating & Air Conditioning. Once in a while the loss of warm air from your gas furnace calls for a large repair, but a lot of time it can be an easy fix. Here are some of the main reasons your gas furnace could be blowing cold air instead of making your home warm and cozy.

Your furnace might be overheating

If you haven’t had ongoing maintenance completed on your gas furnace lately and you’ve forgotten to change your air filter, each could be the reason why your furnace is blowing cool air. A dirty air filter can stop air from flowing freely through your furnace. If this occurs, the furnace could overheat and shut down its burner.

Your pilot light may have gone out

Sometimes 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 systems, for a breeze to put out 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 fight to stay lit and leave you in the cold.

Your ducts may not be properly sealed

When ducts are correctly sealed or if they have any cracks or holes in them, you may be losing a lot of heated air before it can get to the vents.
