Why Your Furnace Could be Blowing Cold Air

October 21, 2016

You hear your HVAC system start up and you’re anticipating a cozy blast of warm air, but instead all you have is cool air blowing. That’s not what you want in the freezing weather!

There are a handful of reasons why your furnace could be giving off cold air. Sunbeam Service Experts Heating & Air Conditioning is here with a few of them to help you detect the issue.

 

  • Thermostat

 

It may 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 heating system will blow constantly, even when it isn’t really heating the air being produced, thus blowing cold air. Turning it to “auto” will make sure the furnace only blows when it’s really heating the air to keep your home warm and comfy.

 

  • Air Filter

 

Typically air filters need to be changed monthly to prevent them from growing dirty and clogged. If air filters aren’t swapped out often enough, the dirty air filter may restrict airflow into your heating equipment. If this happens, it can overheat your furnace, causing the equipment to stop heating as a safety measure.

 

  • Duct Work

 

If your duct work contains leaks, connection issues, or was designed incorrectly, it could let warm air from the heating equipment to seep out. This would not only cause your heating equipment to blow 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 at the desired temperature.

 

There are many other reasons that your heating system could produce cold air.
