Why Your Furnace Could be Blowing Cold Air

October 21, 2016

You listen to your heating system 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 couple reasons why your heating equipment could be putting off cold air. Jack Nelson Service Experts Heating & Air Conditioning is here with a couple of them to help you find the issue.

 

  • Thermostat

 

It could feel silly, but the thermostat is the first place you should check. It’s the starting point for any heating technician, too. Verify 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 really heating the air coming out, 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 monthly to keep them from becoming dirty and clogged. If your filters aren’t replaced often enough, the soiled air filter may restrict airflow into your heating system. If this occurs, it can overheat your system, causing the furnace to stop heating as a safeguard.

 

  • Duct Work

 

If your duct work has leaks, connection problems, or was not designed correctly, it could let warm air from the furnace to leak out. This would not only cause your furnace to produce cold air, it could actually run up your heating bills since your furnace is heating non-living space, and will have to work more to keep your home comfortable.
