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 giving a chill to your Tuscaloosa home, it’s time to reach out to KDM Service Corporation. Sometimes a lack of warm air from your gas furnace calls for a big repair, but many times it can be an easy fix. Here are a few of the more common 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 done on your gas furnace lately and you’ve neglected to replace your air filter, both 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 cause 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, particularly with older models, for a gust of air to smother 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 cause challenges for your gas furnace, so can other furnace components if they aren’t properly 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 sealed properly or if they have any cracks or holes in them, you might be losing a lot of heated air before it can get to the vents.
