Why is My Gas Furnace Blowing Cold Air?

Heating

As the weather changes, the more you feel the cooler air blustering outside. And … inside your home? If your gas furnace is blowing cold air and adding a chill to your Ontario home, it’s time to contact Stan's Heating, Inc . Sometimes an absence of warm air from your gas furnace results in a major repair, but a lot of time it can be a simple fix. Here are several reasons your gas furnace might be blowing cold air instead of making your home warm and cozy.

Your furnace might be overheating

If you haven’t had routine maintenance performed on your gas furnace for some time and you’ve neglected to replace your air filter, each could indicate why your furnace is blowing colder air. A dirty air filter can block air from flowing freely through your furnace. When this happens, the furnace might overheat and force the burner to shut down.

Your pilot light may have gone out

It’s probable a lack of warm air from your gas furnace can be related to something as simple as a pilot light that’s gone out. It’s possible, specifically with older furnaces, for a breeze to put out a pilot light. Other reasons for an extinguished pilot light are defective gas valves or a faulty thermocouple.

Your furnace is dirty

Just as a dirty air filter can mean challenges 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 fight 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 properly sealed or if they have any cracks or holes in them, you may be losing a lot of heated air before it can get to the vents.
