Why Your Furnace Could be Blowing Cold Air

October 21, 2016

You listen to your furnace start up and you’re expecting a comfy blast of warm air, but instead all you feel is cool air blowing. That’s not preferable in the freezing weather!

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

 

  • Thermostat

 

It may feel 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 and not “on.” If the thermostat is set to “on” then your heating system will blow continuously, even when it is not actually heating the air being released, thus blasting 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

 

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

 

  • Duct Work

 

If your duct work includes leaks, connection troubles, or was designed incorrectly, it could let warm air from the furnace to leak out. This would not only cause your heating equipment to produce cold air, it could seriously run up your heating bills since your heating equipment is heating non-living space, and will have to work overtime to keep your home warm.
