Furnace is Blowing

One of the most frustrating things that can happen during winter is when your furnace starts blowing cold air instead of heat. After all, you rely on your furnace to keep your home warm and comfortable when the temperatures outside start to drop. So, what causes a furnace to blow cold air, and how can you fix the problem? In this article, we’ll take a look at three of the most common reasons why your furnace may be blowing cold air, as well as some potential solutions.

1. The Pilot Light is Out

The pilot light is responsible for igniting the burners in your furnace, so if it’s lit, then your furnace will be able to produce heat. If you think the pilot light in your furnace has gone out, you’ll need to relight it. This is typically a simple process, but if it is still not happening, then there must be some underlying issues. In this case, your best bet would be to contact a professional technician for heating and air repair in Atlanta, as they’ll be able to get your furnace up and running again in no time.

2. There’s a Problem with the Thermostat

Another potential reason why your furnace may be blowing cold air is that there’s a problem with the thermostat. This could be due to a variety of issues, such as a loose wire or a faulty sensor. It may also be that the thermostat is not properly calibrated, which can also cause furnace problems. To rule out the thermostat as the problem, you can try resetting it or replacing the batteries. If that doesn’t work, then you’ll need to call in a professional for heating and air repair.

3. The Furnace is Too Old

Older furnaces may not be as efficient as newer models, and as a result, they may not be able to produce enough heat to keep your home comfortable. If your furnace is over 15 years old, it may be time to start shopping for a replacement. A new furnace may be a significant investment, but it will be worth it in the long run, as you’ll likely see a decrease in your energy bills. However, it will also benefit if you know the cost of replacing your furnace, as it will give you a better understanding of what to expect and how to budget for the project.


Now you know some of the most common reasons why your furnace may be blowing cold air instead of heat. If you’re having issues with your furnace, then contact a professional technician to diagnose and fix the problem for you. They will have it up and running in no time so that you can stay warm all winter long!
