Why is My Gas Furnace Blowing Cold Air?

As the seasons change, the more you feel the colder air gusting outside. And … inside your home? If your gas furnace is blowing cold air and adding a chill to your Genoa home, it’s time to reach out to Assured Appliance and Heating & Air. Occasionally an absence of warm air from your gas furnace results in a big repair, but many times it can be a small fix. Here are some of the main reasons your gas furnace may be blowing cold air instead of warming up your house.

Your furnace might be overheating

If you haven’t had ongoing maintenance performed on your gas furnace lately and you’ve neglected to replace your air filter, both could be the reason why your furnace is blowing colder air. A dirty air filter can stop air from flowing freely through your furnace. When this happens, the furnace might overheat and force the burner to shut down.

Your pilot light may have gone out

It could be that 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, particularly with older furnaces, for a gust of air to extinguish a pilot light. Other reasons for an extinguished pilot light are damaged 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 correctly 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 sealed properly or if they have any cracks or holes in them, you could be losing a lot of heated air before it can get to the vents.
