As the seasons change, the more you feel the colder air blustering outside. And … right inside your house? If your gas furnace is blowing cold air and putting a chill to your Stuart home, it’s time to reach out to Breathe Healthier Air. Occasionally an absence of warm air from your gas furnace calls for a major repair, but a lot of time it can be a small fix. Here are a few of the more common reasons your gas furnace might 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 recently and you’ve overlooked changing your air filter, both could be the reason why your furnace is blowing cold air. A dirty air filter can block air from flowing freely through your furnace. When this happens, the furnace may 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 related to something as simple as a pilot light that’s gone out. It’s possible, specifically with older systems, for a breeze to extinguish 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 correctly cleaned. A dirty gas burner or flame sensor could cause your furnace to struggle 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.
