Why is My Gas Furnace Blowing Cold Air?

Heating

As the seasons change, the more you feel the colder air gusting outside. And … right inside your house? If your gas furnace is blowing cold air and giving a chill to your Lodi home, it’s time to contact Tokay Heating and Air Conditioning. Occasionally the loss of warm air from your gas furnace means a big repair, but often 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 keeping your home toasty.

Your furnace could be overheating

If you haven’t had regular maintenance completed on your gas furnace for some time and you’ve forgotten to change your air filter, each could indicate why your furnace is blowing colder air. A dirty air filter can block air from flowing freely through your furnace. If that happens, the furnace might overheat and force 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, especially with older systems, for a draft to smother 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 problems 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 reduce the warmth inside your house.

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 might be losing a lot of heated air before it even reaches the vents throughout the home.
