When your furnace comes on during the cool fall and winter months, you just expect it to provide your house with comfortable warm air. And, most of the time, that is exactly what will happen. But what if the furnace is blowing cold air instead of warm? What is going wrong and how can it be fixed? Let’s dive into that question in the article below.

A Simple Check
If your furnace is not warming your home properly, make sure the thermostat is set to the proper temperature. It’s possible that you have your settings wrong and the fan is running without even trying to heat the house.
Take a look at how your thermostat is set just to confirm that this isn’t the underlying problem. If this is the issue, you’ll likely see something on the screen that says “Fan Only” or something similar – turn that off and set the temperature to what you would like it to reach inside the home. If this isn’t the problem, you will have eliminated this basic point and can move on to consider other issues.
The Next Step for a Furnace Blowing Cold Air
If you have dealt with the thermostat and didn’t find anything that corrects the issue, your next step should be to call in an HVAC team like Walker Air • Plumbing • Electric. Why go right to this step instead of trying to take other actions on your own? Simply put, HVAC equipment is complicated and can even be dangerous when repairs are attempted by inexperienced individuals. Even if you are proud of your DIY skills, leave this one to the pros.
Any time you spend trying to fix the problem yourself is likely to be wasted and you’ll eventually need professional help anyway to get up and running. Save yourself the hassle, and the money you might spend buying equipment or tools to try fixing it on your own, and just reach out to Walker straight away. This is the best way to make sure the warm air starts flowing again as soon as possible.
We’ve established that calling the pros is the right approach when your furnace isn’t heating correctly. With that said, it’s still worthwhile to educate yourself on this issue so you know what you might be facing and what it might take to fix the problem. Here are a few of the potential problems that can lead to a furnace blowing cold air –
- Pilot lights out. If your furnace utilizes a pilot light, it’s possible that the light has gone out. Without a pilot light available, the burners won’t fire up when the furnace comes on, and the air distributed throughout the house will not be warmed. This could be a relatively quick fix, or it could be indicative of a bigger problem that will need to be repaired.
- Ductwork damage. The ductwork in your home is responsible for carrying the warmed (or cooled) air from a central location out to all the vents. If one or more of those ducts becomes damaged, however, the warmed air will escape before it ever reaches the vents, and your house will stay cold as a result. An experienced HVAC team will be able to test your system to determine if ductwork damage is a likely culprit for the poor performance of the furnace.
- Clogged lines. For relatively new systems, the condensate line needs to drain properly to get moisture away from the furnace and allow everything to keep running as it should. These lines normally do their work out of sight and out of mind, but it’s possible for a clog to develop. If the line gets clogged, your furnace may not light and the air won’t be warmed as you expected.
