As the weather changes, the more you feel the cool air blustering outside. And … inside your home? If your gas furnace is blowing cold air and giving a chill to your Port St. Lucie home, it’s time to contact Custom Air Systems Inc. Occasionally an absence of warm air from your gas furnace calls for a large repair, but often it can be a simple fix. Here are some of the main reasons your gas furnace may be blowing cold air instead of making your home warm and cozy.
Your furnace may be overheating
If you haven’t had routine maintenance performed on your gas furnace for some time and you’ve neglected to replace your air filter, either could indicate 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 may 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 related to something as simple as a pilot light that’s gone out. It’s possible, particularly with older systems, 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 mean challenges 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 fight 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 properly sealed or if they have any cracks or holes in them, you might be losing a lot of heated air before it even reaches the vents throughout the home.
