As the seasons change, the more you feel the cool air blustering outside. And … in your home? If your gas furnace is blowing cold air and giving a chill to your Elk River home, it’s time to call Home Comfort Heating & Air. Occasionally the loss of warm air from your gas furnace calls for a large repair, but often it can be a simple fix. Here are some of the main reasons your gas furnace could be blowing cold air instead of warming up your house.
Your furnace could be overheating
If you haven’t had regular maintenance completed on your gas furnace lately and you’ve forgotten to change your air filter, either could signal why your furnace is blowing cold air. A dirty air filter can block air from flowing freely through your furnace. If this occurs, 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 credited to something as simple as a pilot light that’s gone out. It’s possible, specifically with older furnaces, for a gust of air to smother a pilot light. Other reasons for an extinguished pilot light are defective 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 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
If your ducts aren’t properly 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.
