Why is My Gas Furnace Blowing Cold Air?

Heating

As the weather changes, 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 Marshall home, it’s time to reach out to All Elements Heating & Air LLC. Occasionally an absence of warm air from your gas furnace calls for a major repair, but a lot of time it can be a simple fix. Here are some of the main reasons your gas furnace might be blowing cold air instead of keeping your home toasty.

Your furnace could be overheating

If you haven’t had routine maintenance done on your gas furnace recently and you’ve overlooked changing your air filter, both could be the reason 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 shut down its burner.

Your pilot light may have gone out

It’s probable 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 models, for a draft to put out a pilot light. Other causes of 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 challenges 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 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 might be losing a lot of heated air before it even reaches the vents throughout the home.
