Why Your Furnace Could be Blowing Cold Air

October 21, 2016

You listen to your heating system kick on and you’re anticipating a cozy blast of warm air, but instead all you feel is cool air blowing. That’s not what you want when it’s cold outside!

There are a handful of reasons why your furnace 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 feel silly, but the thermostat is where you should start. It’s the first place any heating system technician will check, too. Verify the system is set to “auto and not “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 actually heating the air to keep your home warm and comfortable.

 

  • Air Filter

 

Most air filters need to be changed once a month to prevent them from growing dirty and clogged. If air filters aren’t changed often enough, the soiled air filter may restrict airflow into your furnace. 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 escape out. This would not only cause your heating equipment to blow cold air, it could significantly run up your energy bills since your heating equipment is heating non-living space, and will have to work more to keep your home warm.
