Why is My Gas Furnace Blowing Cold Air?

As the temps change, the more you feel the cooler air gusting 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 call KDM Service Corporation. Once in a while the loss of warm air from your gas furnace results in a major repair, but a lot of time it can be a small fix. Here are several reasons your gas furnace may be blowing cold air instead of keeping your home toasty.

Your furnace might be overheating

If you haven’t had ongoing maintenance completed on your gas furnace lately 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 stop air from flowing freely through your furnace. If that happens, the furnace may 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, particularly with older models, for a gust of air to put out a pilot light. Other reasons for an extinguished pilot light are damaged gas valves or a faulty thermocouple.

Your furnace is dirty

Just as a dirty air filter can cause issues 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 not be able to bring warmth to your home.

Your ducts may not be properly sealed

When ducts are correctly sealed or if they have any cracks or holes in them, you might be losing a lot of heated air before it ever reaches your vents.
