As the seasons change, the more you feel the colder air blustering outside. And … right inside your house? If your gas furnace is blowing cold air and putting a chill to your Erie home, it’s time to call Patterson & Stirling Inc. Sometimes the loss of warm air from your gas furnace means a large repair, but often it can be an easy fix. Here are a few of the more common reasons your gas furnace could be blowing cold air instead of keeping your home toasty.
Your furnace could be overheating
If you haven’t had regular maintenance done on your gas furnace recently and you’ve forgotten to change your air filter, either could signal why your furnace is blowing colder air. A dirty air filter can prevent air from flowing freely through your furnace. If this occurs, the furnace may overheat and shut down its burner.
Your pilot light may have gone out
It could be that 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, particularly with older systems, for a gust of air to extinguish 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 mean 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 fight to stay lit and leave you in the cold.
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 may be losing a lot of heated air before it can get to the vents.
