Why is My Gas Furnace Blowing Cold Air?

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

Your furnace could be overheating

If you haven’t had routine maintenance completed on your gas furnace lately and you’ve forgotten to change your air filter, both could be the reason why your furnace is blowing cold air. A dirty air filter can prevent air from flowing freely through your furnace. When this happens, 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 related to something as simple as a pilot light that’s gone out. It’s possible, specifically with older furnaces, for a gust of air to extinguish a pilot light. Other causes of 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 fight to stay lit and leave you in the cold.

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 might be losing a lot of heated air before it can get to the vents.
