Why is My Gas Furnace Blowing Cold Air?

Heating

As the weather changes, the more you feel the cooler air blustering outside. And … in your home? If your gas furnace is blowing cold air and giving a chill to your Redford home, it’s time to contact Airtronic Heating & Cooling. Occasionally the loss of warm air from your gas furnace results in a large repair, but a lot of time it can be an easy fix. Here are some of the main reasons your gas furnace may be blowing cold air instead of warming up your house.

Your furnace might be overheating

If you haven’t had ongoing maintenance completed on your gas furnace for some time and you’ve overlooked changing your air filter, both could signal why your furnace is blowing cold air. A dirty air filter can prevent air from flowing freely through your furnace. If that happens, the furnace could 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 credited 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 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 result in 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 reduce the warmth inside your house.

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