Why is My Gas Furnace Blowing Cold Air?

As the weather changes, the more you feel the cool air blustering outside. And … right inside your house? If your gas furnace is blowing cold air and adding a chill to your Alice home, it’s time to contact Rescue Heating & Air . Sometimes the loss of warm air from your gas furnace means a large repair, but many times it can be a small 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 might be overheating

If you haven’t had routine maintenance completed on your gas furnace lately and you’ve forgotten to change your air filter, each could signal why your furnace is blowing cold air. A dirty air filter can block air from flowing freely through your furnace. When this happens, the furnace may overheat and force the burner to shut down.

Your pilot light may have gone out

Sometimes 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 draft to smother 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 result in issues for your gas furnace, so can other furnace components if they aren’t appropriately 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 might be losing a lot of heated air before it can get to the vents.
