Why is My Gas Furnace Blowing Cold Air?

Heating

As the seasons change, the more you feel the colder air gusting outside. And … in your home? If your gas furnace is blowing cold air and putting a chill to your Napoleon and Northwest Ohio home, it’s time to reach out to Von Deylen Plumbing & Heating Inc.. Once in a while the loss of warm air from your gas furnace calls for a big repair, but many times it can be an easy fix. Here are some of the main reasons your gas furnace may be blowing cold air instead of keeping your home toasty.

Your furnace may be overheating

If you haven’t had ongoing maintenance performed on your gas furnace recently and you’ve neglected to replace your air filter, either could indicate 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 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 attributed to something as simple as a pilot light that’s gone out. It’s possible, especially with older systems, 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 mean 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 fight to stay lit and leave you in the cold.

Your ducts may not be properly sealed

If your ducts aren’t properly sealed or if they have any cracks or holes in them, you could be losing a lot of heated air before it ever reaches your vents.
