Why Your Furnace Could be Blowing Cold Air

You notice your heating system kick on and you’re ready for a comfy blast of warm air, but instead all you get is cool air blowing. That’s not what you want when it’s cold outside! 

There are a couple reasons why your furnace could be putting off cold air. Service Experts Heating & Air Conditioning is here with some of them to help you find the problem. 

• Thermostat 

It could sound silly, but the thermostat is the first place you should check. It’s the starting place for any furnace technician, too. Make sure the system is set to “auto and not “on.” If the thermostat is set to “on” then your furnace will blow continuously, even when it isn’t heating the air being produced, thus blasting cold air. Flipping it to “auto” will make sure the heating equipment only blows when it’s actually heating the air to keep your home warm and cozy. 

• Air Filter 

Most air filters need to be changed every month to avoid them from getting dirty and clogged. If air filters aren’t swapped out often enough, the clogged air filter may impede airflow into your heating system. If this takes place, it can overheat your furnace, causing the furnace to stop heating as a safety precaution. 

• Duct Work 

If your duct work has leaks, connection issues, or was not designed properly, it could permit warm air from the heating system to seep out. This would not only cause your heating system to produce cold air, it could seriously run up your energy bills since your heating equipment is heating non-living space, and will have to work harder to keep your home warm.
