Why is My Gas Furnace Blowing Cold Air?

Heating

As the seasons change, the more you feel the colder air blowing outside. And … right inside your house? If your gas furnace is blowing cold air and adding a chill to your Carson City home, it’s time to call Anderson Heating & A/C. Once in a while the loss of warm air from your gas furnace means a big repair, but a lot of time it can be a simple fix. Here are several reasons your gas furnace may be blowing cold air instead of keeping your home toasty.

Your furnace may be overheating

If you haven’t had ongoing maintenance completed on your gas furnace recently and you’ve neglected to replace your air filter, each could indicate why your furnace is blowing cold air. A dirty air filter can block air from flowing freely through your furnace. If this occurs, the furnace may overheat and cause 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 credited to something as simple as a pilot light that’s gone out. It’s possible, especially with older furnaces, for a gust of air to extinguish a pilot light. Other reasons for an extinguished pilot light are faulty gas valves or a faulty thermocouple.

Your furnace is dirty

Just as a dirty air filter can result in problems 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 struggle 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 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.
