Why is My Gas Furnace Blowing Cold Air?

Heating

As the weather changes, the more you feel the cooler air gusting outside. And … inside your home? If your gas furnace is blowing cold air and adding a chill to your Colorado Springs home, it’s time to call Mitchell Heating. Sometimes the loss of warm air from your gas furnace means a large repair, but many times it can be a simple fix. Here are several reasons your gas furnace could be blowing cold air instead of keeping your home toasty.

Your furnace might be overheating

If you haven’t had regular maintenance done on your gas furnace recently and you’ve overlooked changing your air filter, both could be the reason why your furnace is blowing cool air. A dirty air filter can block air from flowing freely through your furnace. If this occurs, the furnace could 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 systems, for a breeze to put out a pilot light. Other factors when it comes to an extinguished pilot light are damaged 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 properly 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 may be losing a lot of heated air before it ever reaches your vents.
