As the temps change, the more you feel the cool air gusting outside. And … in your home? If your gas furnace is blowing cold air and adding a chill to your Huntsville home, it’s time to call All Weather Heating & Air Conditioning Inc. Sometimes an absence 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 several reasons your gas furnace might be blowing cold air instead of warming up your house.
Your furnace might be overheating
If you haven’t had routine maintenance completed on your gas furnace recently and you’ve forgotten to change your air filter, either could signal why your furnace is blowing cold air. A dirty air filter can prevent air from flowing freely through your furnace. When this happens, the furnace may overheat and shut down its burner.
Your pilot light may have gone out
It’s probable 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, particularly with older furnaces, for a breeze to put out a pilot light. Other causes of an extinguished pilot light are damaged 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 appropriately cleaned. A dirty gas burner or flame sensor could cause your furnace to battle to stay lit and reduce the warmth inside your house.
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 ever reaches your vents.
