As the weather changes, the more you feel the cool air blowing outside. And … inside your home? If your gas furnace is blowing cold air and adding a chill to your Neptune City home, it’s time to contact Aggressive Mechanical. Once in a while an absence of warm air from your gas furnace means a big repair, but often it can be a small fix. Here are some of the main reasons your gas furnace may be blowing cold air instead of warming up your house.
Your furnace might be overheating
If you haven’t had ongoing maintenance done on your gas furnace lately and you’ve forgotten to change your air filter, each could be the reason why your furnace is blowing colder air. A dirty air filter can stop air from flowing freely through your furnace. If that 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 related to something as simple as a pilot light that’s gone out. It’s possible, especially with older furnaces, for a breeze to put out a pilot light. Other factors when it comes to an extinguished pilot light are faulty gas valves or a faulty thermocouple.
Your furnace is dirty
Just as a dirty air filter can mean 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 sealed properly or if they have any cracks or holes in them, you could be losing a lot of heated air before it ever reaches your vents.
