Why is My Gas Furnace Blowing Cold Air?

As the temps change, the more you feel the cooler air gusting outside. And … in your home? If your gas furnace is blowing cold air and putting a chill to your Williamsport home, it’s time to contact Lycoming Heating Company. Once in a while a lack of warm air from your gas furnace results in a big repair, but many times it can be a simple fix. Here are a few of the more common reasons your gas furnace could be blowing cold air instead of warming up your house.

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, either could be the reason why your furnace is blowing colder air. A dirty air filter can stop air from flowing freely through your furnace. If this occurs, the furnace could overheat and force the burner to shut down.

Your pilot light may have gone out

Sometimes a lack of warm air from your gas furnace can be attributed to something as simple as a pilot light that’s gone out. It’s possible, especially with older furnaces, for a gust of air to smother 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 challenges 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 leave you in the cold.

Your ducts may not be properly sealed

When ducts are correctly sealed or if they have any cracks or holes in them, you could be losing a lot of heated air before it even reaches the vents throughout the home.
