As the temps change, the more you feel the cooler air gusting outside. And … inside your home? If your gas furnace is blowing cold air and adding a chill to your Williamsport home, it’s time to contact Lycoming Heating Company. Sometimes an absence of warm air from your gas furnace results in a big repair, but many times it can be an easy fix. Here are several reasons your gas furnace might be blowing cold air instead of keeping your home toasty.
Your furnace could be overheating
If you haven’t had ongoing maintenance done on your gas furnace recently and you’ve forgotten to change your air filter, each could signal why your furnace is blowing cool air. A dirty air filter can stop air from flowing freely through your furnace. If that 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 credited to something as simple as a pilot light that’s gone out. It’s possible, specifically with older models, for a gust of air to put out a pilot light. Other causes of an extinguished pilot light are defective 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 properly 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 could be losing a lot of heated air before it can get to the vents.
