As the temps change, the more you feel the cool air blowing outside. And … right inside your house? If your gas furnace is blowing cold air and adding a chill to your Moline home, it’s time to call J.L. Brady Company LLC. Sometimes an absence 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 might be blowing cold air instead of warming up your house.
Your furnace may be overheating
If you haven’t had routine maintenance done on your gas furnace lately and you’ve neglected to replace your air filter, each could be the reason 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 could 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 attributed to something as simple as a pilot light that’s gone out. It’s possible, especially with older systems, for a gust of air to extinguish a pilot light. Other reasons for 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.
