Why is My Gas Furnace Blowing Cold Air?

As the temps change, the more you feel the colder air gusting outside. And … right inside your house? If your gas furnace is blowing cold air and adding 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 calls for a big repair, but often it can be an easy fix. Here are a few of the more common reasons your gas furnace could be blowing cold air instead of making your home warm and cozy.

Your furnace may be overheating

If you haven’t had routine maintenance done on your gas furnace for some time and you’ve overlooked changing 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

Sometimes 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, particularly with older systems, for a gust of air 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 could be losing a lot of heated air before it even reaches the vents throughout the home.
