Why is My Gas Furnace Blowing Cold Air?

As the weather changes, the more you feel the cool air blowing outside. And … in your home? If your gas furnace is blowing cold air and giving a chill to your Dresden home, it’s time to call McFadden Heating & Cooling. Sometimes the loss of warm air from your gas furnace calls for a big repair, but often it can be a small fix. Here are a few of the more common reasons your gas furnace could be blowing cold air instead of keeping your home toasty.

Your furnace may be overheating

If you haven’t had routine maintenance completed on your gas furnace lately and you’ve neglected to replace your air filter, each could signal why your furnace is blowing colder air. A dirty air filter can block air from flowing freely through your furnace. If that happens, the furnace might overheat and shut down its burner.

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 models, for a gust of air 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 mean 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 battle to stay lit and leave you in the cold.

Your ducts may not be properly sealed

When ducts are correctly sealed or if they have any cracks or holes in them, you could be losing a lot of heated air before it can get to the vents.
