Why is Your Furnace Blowing Cold Air?

Furnaces are supposed to shield you and keep you insulated from the sometimes harsh Chicago weather. So when it starts to blow cold air, it can be confusing and difficult to diagnose the problem. Fortunately, just because your furnace is blowing cold air doesn’t necessarily mean you’re going to need furnace repair in Ravenswood. In fact, there are a few things that cause furnaces to blow cold air that you can troubleshoot yourself.

Of course, in some cases, you’ll have to call in HVAC professionals for furnace repair in Ravenswood. But before you pick up the phone, run through the rest of this post for ideas on what might be going wrong.

A Clogged Air Filter

This is one of the issues that cause furnaces to blow cold air that is fairly easy to solve. To find out if your air filter is clogged, look for debris in the filter. And if you’re not sure if it’s clogged, replace the air filter anyway as this is something you should do at least once a month.

It’s Still Warming Up

In some cases, you may feel some cold air coming out of your furnace when it first turns on. This is totally normal, especially in the colder months because sometimes the furnace will require a few minutes to heat up. Just wait for the furnace to warm up and don’t worry about furnace repair in Ravenswood just yet.

The Thermostat is On

It’s a simple thing, but many people have their thermostat’s fan set “on” instead of “auto.” This ensures that the fan will run which causes cool air to be pushed out since the furnace isn’t doing any heating. To fix this problem, simply change the thermostat’s settings to “auto” so the fan only blows when the air is getting heated.

The Pilot Light Has Gone Out

This is a common problem in older furnaces which you can solve if you’re comfortable doing so. You’ll just need to follow your unit’s manufacturer’s instruction manual for relighting the pilot light. Just remember, if you’re at all uncomfortable or not sure about how to relight the pilot light safely, call an HVAC professional.
