As the seasons change, the more you feel the cooler air blustering outside. And … right inside your house? If your gas furnace is blowing cold air and putting a chill to your Marshfield home, it’s time to contact House of Heating Incorporated. Once in a while an absence of warm air from your gas furnace results in a large repair, but a lot of time it can be a simple fix. Here are some of the main reasons your gas furnace might be blowing cold air instead of making your home warm and cozy.
Your furnace could be overheating
If you haven’t had ongoing maintenance completed on your gas furnace lately and you’ve overlooked changing your air filter, each could indicate why your furnace is blowing cool air. A dirty air filter can prevent air from flowing freely through your furnace. When this happens, the furnace might overheat and shut down its burner.
Your pilot light may have gone out
Sometimes a lack of warm air from your gas furnace can be attributed to something as simple as a pilot light that’s gone out. It’s possible, especially with older systems, 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 appropriately 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
When ducts are correctly sealed 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.
