Why is My Gas Furnace Blowing Cold Air?

Heating

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 putting a chill to your Hamilton home, it’s time to reach out to Carefree Heating and Cooling, LLC. Sometimes a lack of warm air from your gas furnace results in a big repair, but often 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 might be overheating

If you haven’t had regular maintenance done on your gas furnace lately and you’ve overlooked changing your air filter, each could be the reason why your furnace is blowing cold air. A dirty air filter can block 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

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 systems, for a draft to put out a pilot light. Other causes of an extinguished pilot light are faulty 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 fight 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 even reaches the vents throughout the home.
