Why Your Furnace Could be Blowing Cold Air

October 21, 2016

You listen to your furnace kick on and you’re expecting a comfortable blast of warm air, but instead all you get is cool air blowing. That’s not what you want in the freezing weather!

There are a couple reasons why your heating equipment could be blowing cold air. Service Experts Heating & Air Conditioning is here with some of them to help you find the culprit.

 

  • Thermostat

 

It might sound silly, but the thermostat is the first thing you want to look at. It’s the starting place for any furnace technician, too. Make sure the system is set to “auto as opposed to “on.” If the thermostat is set to “on” then your furnace will blow continuously, even when it isn’t really heating the air coming out, thus blowing cold air. Turning it to “auto” will make sure the furnace only blows when it’s actually heating the air to keep your home warm and cozy.

 

  • Air Filter

 

Typically air filters need to be changed monthly to keep them from growing dirty and clogged. If they aren’t changed often enough, the dirty air filter may impede airflow into your heating system. If this happens, it can overheat your equipment, causing the equipment to stop heating as a safety precaution.

 

  • Duct Work

 

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