Why Is My Furnace Blowing Cold Air?

While it may be alarming to feel cold air coming out of your furnace, it’s not necessarily indicative of a major problem. Instead, it could simply be that the condensate line is clogged or the pilot light is out. Let’s look at a few common reasons why a furnace could be blowing cold air.

The Air Filter Is Clogged

When an air filter gets clogged, it may cause dust or other particles to linger in the air or on furnace components. This may result in a motor blower or similar component overheating.



If the temperature gets too hot, it could trigger a setting that prevents the air from being blown out of the furnace. This feature is designed to ensure that heat exchange and other sensitive components don’t crack or break.

The Fan Setting May Need To Be Changed

Ideally, the fan will be set to automatic to ensure that it only circulates air after it has been warmed inside of the furnace. The folks at Expert Air Control in Puyallup will be glad to come to your home and take a look at your furnace settings.

We can set the fan to the right setting as well as troubleshoot any other problems that it may be having. If necessary, we can replace your current furnace with one that may be more reliable and efficient.

The Pilot Light Isn’t Working

Older furnaces rely on a pilot light to ensure that the furnace is able to generate and circulate warm air. If the light is out, your heating system is not going to function properly.

In many cases, you can follow the instructions in the owner’s manual to resolve the issue. However, if you don’t feel comfortable doing so, you can call one of our technicians for assistance.
