Why Your Furnace Could be Blowing Cold Air

You listen to your heating system kick on and you’re expecting a comfortable blast of warm air, but instead all you feel is cool air blowing. That’s no good in the freezing weather! 

There are a few reasons why your heating equipment could be blowing cold air. Levy & Son Service Experts is here with a few of them to help you find the culprit. 

  • Thermostat 

It could sound silly, but the thermostat is where you should start. It’s the first place any heating system technician will check, too. Confirm 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 coming out, thus blowing cold air. Turning it to “auto” will make sure the heating equipment only blows when it’s actually heating the air to keep your home warm and comfortable. 

  • Air Filter 

Most air filters need to be changed once a month to avoid them from growing dirty and clogged. If they aren’t replaced often enough, the dirty air filter may impede airflow into your furnace. If this occurs, it can overheat your system, causing the furnace to stop heating as a safety measure. 

  • Duct Work 

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

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