Why Your Furnace Could be Blowing Cold Air

You hear your furnace turn on and you’re ready for a cozy blast of warm air, but instead all you have is cool air blowing. That’s not what you want in freezing temperatures! 

There are a few reasons why your heating system could be blowing cold air. Stevenson Service Experts is here with a couple of them to help you find the problem. 

  • Thermostat 

It could sound silly, but the thermostat is where you should start. It’s the starting place for any furnace technician, too. Verify the system is set to “auto as opposed to “on.” If the thermostat is set to “on” then your furnace will blow constantly, even when it isn’t heating the air coming out, thus putting off cold air. Flipping it to “auto” will make sure the furnace only blows when it’s truly heating the air to keep your home warm and comfortable. 

  • Air Filter 

Typically air filters need to be changed once a month to prevent them from becoming dirty and clogged. If air filters aren’t replaced often enough, the dirty air filter may obstruct airflow into your heating equipment. If this occurs, it can overheat your equipment, causing the system to stop heating as a safety measure. 

  • Duct Work 

If your duct work includes 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 equipment to give off cold air, it could significantly run up your energy bills since your heating equipment is heating non-living space, and will have to work more to keep your home comfortable. 

There are multiple other reasons that your heating equipment could give off cold air.
