As the temps change, the more you feel the colder air gusting outside. And … inside your home? If your gas furnace is blowing cold air and adding a chill to your Kearney home, it’s time to call Thurston Heating & Air Conditioning. Once in a while the loss of warm air from your gas furnace means a large repair, but often it can be an easy fix. Here are some of the main reasons your gas furnace could be blowing cold air instead of making your home warm and cozy.
Your furnace might be overheating
If you haven’t had ongoing maintenance completed on your gas furnace recently and you’ve overlooked changing your air filter, each could indicate 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 may overheat and force 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, especially with older models, for a gust of air to put out a pilot light. Other reasons for an extinguished pilot light are defective gas valves or a faulty thermocouple.
Your furnace is dirty
Just as a dirty air filter can cause challenges 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 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 might be losing a lot of heated air before it even reaches the vents throughout the home.
