As the temps change, the more you feel the cool air gusting outside. And … in your home? If your gas furnace is blowing cold air and giving a chill to your Lawrence home, it’s time to call Scott Temperature. Occasionally the loss of warm air from your gas furnace results in a major repair, but many times it can be a small fix. Here are a few of the more common reasons your gas furnace could be blowing cold air instead of warming up your house.
Your furnace might be overheating
If you haven’t had regular maintenance performed on your gas furnace recently and you’ve neglected to replace your air filter, each 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 could overheat and force the burner to shut down.
Your pilot light may have gone out
It could be that 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 draft to smother 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 mean problems for your gas furnace, so can other furnace components if they aren’t properly cleaned. A dirty gas burner or flame sensor could cause your furnace to struggle to stay lit and leave you in the cold.
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 ever reaches your vents.
