Is your furnace running, but blowing out cold air? Is your home feeling especially chilly? As frustrating as this might be, we are here to help you diagnose the issue. In some cases, it might be a simple fix. In other instances, you may need the assistance of a professionally trained HVAC technician.

Getting to the Root of the Problem

Here are some common reasons why your furnace may be blowing out cold air:

Your filter is clogged. When you have an issue with your heating system, such as a furnace, it’s a good idea to change your filters—especially if you haven’t done so in quite some time. If your heater is clogged, the airflow is restricted, and the heater cannot heat your home.
Something may be wrong with the fuel source. For any furnace, fuel is the main source of heat. Depending on the type of furnace that you have in your home, if you aren’t feeling warm air, it’s important to determine if the issue is electrical or from the gas supply valve. Of course, if an issue is present with your gas valve or ignition system, don’t attempt to fix it on your own; you will need the assistance of a professional HVAC technician.
Your condensate drain may be clogged. Condensate pumps and reservoirs can easily become clogged, which will prevent the burner from lighting and cause your furnace to operate improperly.
Something may be wrong with your ductwork. If your ductwork is damaged, through a leak or something blocking it on the inside, it will block air from getting into your home. If you have a serious leak, much of the air will flow to your attic, and almost none of it will be coming into your house. You may be able to quickly take a look at your ductwork to see if this is the problem at hand. However, it’s more likely that a professional will need to identify the extent of the problem.
Your system may need a reboot. If you have a modern furnace that is controlled through a computer, it can suddenly freeze, just as a desktop computer would. This can impact the fuel delivery while allowing the fan to work. If you reboot the system, it might do the trick and fix itself.

Rely on a Professional for Heating Repair

If your effort to troubleshoot doesn’t resolve the issue of cold air, you will need to get assistance from your heating and cooling service provider. It could be that electronic components are part of the problem, or maybe something as simple as changing your filter will remedy the issue. Regardless of the issue, your technician will work through a series of tests to pinpoint the exact issue.
