Why is My Gas Furnace Blowing Cold Air?

As the temps change, the more you feel the colder air gusting outside. And … right inside your house? If your gas furnace is blowing cold air and putting a chill to your Huntsville home, it’s time to contact All Weather Heating & Air Conditioning Inc. Sometimes an absence of warm air from your gas furnace results in a large 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 may be overheating

If you haven’t had routine maintenance done on your gas furnace lately and you’ve forgotten to change your air filter, each could signal 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 might overheat and cause the burner to shut down.

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 systems, for a breeze to smother a pilot light. Other reasons for an extinguished pilot light are damaged gas valves or a faulty thermocouple.

Your furnace is dirty

Just as a dirty air filter can result in challenges 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 battle 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 may be losing a lot of heated air before it even reaches the vents throughout the home.
