Why is My Gas Furnace Blowing Cold Air?

As the weather changes, the more you feel the cool air blowing outside. And … in your home? If your gas furnace is blowing cold air and adding a chill to your Lake Forest home, it’s time to reach out to 1st Choice Heating & Air Conditioning, Inc.. Occasionally a lack of warm air from your gas furnace calls for a large repair, but a lot of time it can be a small 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 regular maintenance done on your gas furnace lately and you’ve overlooked changing your air filter, both 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 attributed to something as simple as a pilot light that’s gone out. It’s possible, specifically with older systems, for a breeze to extinguish a pilot light. Other factors when it comes to an extinguished pilot light are faulty gas valves or a faulty thermocouple.

Your furnace is dirty

Just as a dirty air filter can cause problems for your gas furnace, so can other furnace components if they aren’t properly 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

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.
