Why is My Gas Furnace Blowing Cold Air?

As the temps change, the more you feel the cool air blowing outside. And … inside your home? If your gas furnace is blowing cold air and giving a chill to your Brandon home, it’s time to reach out to Brandon Heating and Plumbing. Once in a while the loss of warm air from your gas furnace means a big repair, but a lot of time it can be an easy fix. Here are some of the main reasons your gas furnace could be blowing cold air instead of making your home warm and cozy.

Your furnace could be overheating

If you haven’t had ongoing maintenance performed on your gas furnace recently 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 block air from flowing freely through your furnace. If that happens, the furnace might overheat and shut down its burner.

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, especially with older systems, for a draft to extinguish 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 mean 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 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 may be losing a lot of heated air before it even reaches the vents throughout the home.
