Why Your Furnace Could be Blowing Cold Air

October 21, 2016

You listen to your HVAC system turn on and you’re expecting a comfy blast of warm air, but instead all you get is cool air blowing. That’s not preferable when it’s cold outside!

There are a couple reasons why your heating system could be giving off cold air. Boehmers/Cronin Emery Service Experts is here with a few of them to help you detect the problem.

 

  • Thermostat

 

It may sound silly, but the thermostat is the first thing you want to look at. It’s the starting place for any furnace technician, too. Confirm the system is set to “auto as opposed to “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 putting off 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 cozy.

 

  • Air Filter

 

Most air filters need to be changed every month to keep them from becoming dirty and clogged. If air filters aren’t swapped out often enough, the clogged air filter may restrict airflow into your heating equipment. If this occurs, it can overheat your system, causing the equipment to stop heating as a safeguard.

 

  • Duct Work

 

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