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 Bossier City home, it’s time to contact Brooks Heating and Air Conditioning. Occasionally a lack of warm air from your gas furnace calls for a major repair, but many times it can be an easy fix. Here are a few of the more common reasons your gas furnace may be blowing cold air instead of keeping your home toasty.
Your furnace may be overheating
If you haven’t had regular maintenance done on your gas furnace for some time and you’ve neglected to replace your air filter, either could signal 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 might overheat and cause 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 related to something as simple as a pilot light that’s gone out. It’s possible, specifically with older systems, for a gust of air to smother a pilot light. Other causes of an extinguished pilot light are faulty gas valves or a faulty thermocouple.
Your furnace is dirty
Just as a dirty air filter can cause 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 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 may be losing a lot of heated air before it can get to the vents.
