Why is My Gas Furnace Blowing Cold Air?

Heating

As the seasons change, the more you feel the cool air blustering outside. And … right inside your house? If your gas furnace is blowing cold air and adding a chill to your Locust home, it’s time to call Dynamic Comfort Solutions. Sometimes the loss of warm air from your gas furnace calls for a big repair, but a lot of time it can be a small 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 could be overheating

If you haven’t had routine maintenance completed on your gas furnace recently and you’ve neglected to replace your air filter, either could indicate why your furnace is blowing colder air. A dirty air filter can prevent air from flowing freely through your furnace. If that happens, the furnace might 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 attributed to something as simple as a pilot light that’s gone out. It’s possible, particularly with older furnaces, for a draft to extinguish 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 cause problems 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 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 could be losing a lot of heated air before it ever reaches your vents.
