As the temps change, the more you feel the colder air blowing outside. And … in your home? If your gas furnace is blowing cold air and giving a chill to your Wausau home, it’s time to call Gilray Heating and Cooling. Once in a while an absence 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 may be blowing cold air instead of keeping your home toasty.
Your furnace might be overheating
If you haven’t had routine maintenance performed on your gas furnace recently and you’ve forgotten to change your air filter, each could be the reason why your furnace is blowing cool air. A dirty air filter can block air from flowing freely through your furnace. When this happens, the furnace might 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 related to something as simple as a pilot light that’s gone out. It’s possible, specifically with older systems, for a breeze to put out a pilot light. Other reasons for 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 fight to stay lit and not be able to bring warmth to your home.
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.
