As the temps change, the more you feel the colder air blowing outside. And … right inside your house? If your gas furnace is blowing cold air and putting a chill to your McMurray home, it’s time to reach out to Kowalski Heating, Cooling & Plumbing. Sometimes a lack 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 a few of the more common reasons your gas furnace might be blowing cold air instead of making your home warm and cozy.
Your furnace could be overheating
If you haven’t had ongoing maintenance performed on your gas furnace for some time and you’ve overlooked changing your air filter, each could signal why your furnace is blowing colder air. A dirty air filter can block air from flowing freely through your furnace. When this happens, the furnace could overheat and cause the burner to shut down.
Your pilot light may have gone out
It’s probable a lack of warm air from your gas furnace can be attributed 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 put out a pilot light. Other factors when it comes to an extinguished pilot light are damaged 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 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 may be losing a lot of heated air before it even reaches the vents throughout the home.
