As the temps change, the more you feel the cool air gusting outside. And … in your home? If your gas furnace is blowing cold air and putting a chill to your McHenry home, it’s time to call Jett's Heating & Air Inc.. Once in a while an absence of warm air from your gas furnace calls for a large repair, but often it can be an easy fix. Here are some of the main reasons your gas furnace may be blowing cold air instead of warming up your house.
Your furnace might be overheating
If you haven’t had ongoing maintenance completed on your gas furnace recently and you’ve neglected to replace your air filter, either could be the reason why your furnace is blowing cool air. A dirty air filter can prevent 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’s probable a lack of warm air from your gas furnace can be credited to something as simple as a pilot light that’s gone out. It’s possible, especially with older models, for a draft to put out a pilot light. Other causes of an extinguished pilot light are damaged gas valves or a faulty thermocouple.
Your furnace is dirty
Just as a dirty air filter can result in 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 battle 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.
