Why Your Furnace Could be Blowing Cold Air

October 21, 2016

You hear your furnace turn on and you’re expecting a comfy blast of warm air, but instead all you have is cool air blowing. That’s not what you want when it’s cold outside!

There are a few reasons why your heating equipment could be blowing cold air. Jack Nelson Service Experts 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 heating system will blow continuously, even when it isn’t really heating the air being produced, 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 avoid them from getting dirty and clogged. If your filters aren’t replaced often enough, the soiled air filter may obstruct airflow into your heating system. If this occurs, it can overheat your system, causing the system to stop heating as a safeguard.

 

  • Duct Work

 

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