Why Your Furnace Could be Blowing Cold Air

October 21, 2016

You notice your HVAC system start up and you’re anticipating a comfy blast of warm air, but instead all you get is cool air blowing. That’s not what you want in freezing temperatures!

There are a few reasons why your furnace could be giving off cold air. 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 continually, even when it is not actually heating the air coming out, thus blasting cold air. Flipping it to “auto” will make sure the heating system only blows when it’s truly heating the air to keep your home warm and comfy.

 

  • Air Filter

 

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

 

  • Duct Work

 

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