Why Your Furnace Could be Blowing Cold Air

October 21, 2016

You listen to your HVAC system turn on and you’re expecting a comfortable blast of warm air, but instead all you feel is cool air blowing. That’s not preferable in freezing temperatures!

There are a handful of reasons why your heating equipment could be blowing cold air. BW/Cook Service Experts Heating & Air Conditioning is here with some of them to help you locate the issue.

 

  • Thermostat

 

It may feel 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 as opposed to “on.” If the thermostat is set to “on” then your heating system will blow continuously, even when it is not actually heating the air coming out, thus blasting cold air. Turning it to “auto” will make sure the furnace 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 every month to keep them from growing dirty and clogged. If your filters aren’t changed often enough, the soiled air filter may restrict airflow into your heating equipment. If this happens, it can overheat your equipment, causing the equipment to stop heating as a safety precaution.

 

  • Duct Work

 

If your duct work contains leaks, connection troubles, or was designed incorrectly, it could allow warm air from the furnace to seep out. This would not only cause your heating equipment to produce 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 at the desired temperature.
