Why Your Furnace Could be Blowing Cold Air

October 21, 2016

You hear your heating system kick on and you’re anticipating a comfy blast of warm air, but instead all you get is cool air blowing. That’s no good when it’s cold outside!

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

 

  • Thermostat

 

It could sound silly, but the thermostat is the first place you should check. It’s the starting place for any furnace technician, too. Verify the system is set to “auto instead of “on.” If the thermostat is set to “on” then your furnace will blow continually, even when it isn’t really heating the air coming out, thus blasting cold air. Changing it to “auto” will make sure the heating equipment only blows when it’s truly heating the air to keep your home warm and comfortable.

 

  • Air Filter

 

The majority of air filters need to be changed once a month to prevent them from growing dirty and clogged. If they aren’t changed often enough, the soiled air filter may restrict airflow into your heating equipment. If this takes place, it can overheat your system, causing the equipment to stop heating as a safety measure.

 

  • Duct Work

 

If your duct work has leaks, connection troubles, or was not designed correctly, it could let warm air from the heating system to leak out. This would not only cause your heating equipment to blow 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.
