As the temps change, the more you feel the cooler air blowing outside. And … inside your home? If your gas furnace is blowing cold air and giving a chill to your Florissant home, it’s time to call B & B Heating & Cooling. Sometimes an absence of warm air from your gas furnace calls for a big repair, but often it can be a simple fix. Here are several reasons your gas furnace may be blowing cold air instead of making your home warm and cozy.
Your furnace might be overheating
If you haven’t had regular maintenance done on your gas furnace lately and you’ve forgotten to change your air filter, both could be the reason why your furnace is blowing colder air. A dirty air filter can block air from flowing freely through your furnace. If that 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 related to something as simple as a pilot light that’s gone out. It’s possible, especially with older models, for a draft to smother a pilot light. Other factors when it comes to an extinguished pilot light are damaged gas valves or a faulty thermocouple.
Your furnace is dirty
Just as a dirty air filter can result in problems 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 sealed properly 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.
