As the weather changes, the more you feel the cooler air blowing outside. And … right inside your house? If your gas furnace is blowing cold air and putting a chill to your Greensburg home, it’s time to call Wallpe Heating & Cooling. Once in a while an absence of warm air from your gas furnace calls for a major repair, but a lot of time it can be a simple fix. Here are some of the main reasons your gas furnace could be blowing cold air instead of keeping your home toasty.
Your furnace may be overheating
If you haven’t had ongoing maintenance completed on your gas furnace lately and you’ve neglected to replace your air filter, either could be the reason 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 might 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 credited to something as simple as a pilot light that’s gone out. It’s possible, especially with older systems, for a draft to smother a pilot light. Other causes of 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 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
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.
