Why is My Gas Furnace Blowing Cold Air?

As the temps change, the more you feel the colder air blustering outside. And … inside your home? If your gas furnace is blowing cold air and adding a chill to your Winnipeg home, it’s time to call Kirkfield Heating & Air Conditioning. Occasionally the loss of warm air from your gas furnace results in a major repair, but often it can be a simple fix. Here are a few of the more common reasons your gas furnace might be blowing cold air instead of warming up your house.

Your furnace may be overheating

If you haven’t had routine maintenance done on your gas furnace lately 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 stop air from flowing freely through your furnace. If this occurs, the furnace might overheat and cause the burner to shut down.

Your pilot light may have gone out

Sometimes 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, specifically with older furnaces, for a draft to extinguish 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 cause issues for your gas furnace, so can other furnace components if they aren’t appropriately 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 could be losing a lot of heated air before it ever reaches your vents.
