Why Your Furnace Could be Blowing Cold Air

October 21, 2016

You listen to your furnace kick on and you’re ready for a comfortable blast of warm air, but instead all you feel is cool air blowing. That’s not what you want in the freezing weather!

There are a couple reasons why your heating system could be giving off cold air. Levy & Son Service Experts is here with some of them to help you find the issue.

 

  • Thermostat

 

It could sound silly, but the thermostat is the first place you should check. It’s the starting point for any heating technician, too. Confirm the system is set to “auto instead of “on.” If the thermostat is set to “on” then your furnace will blow continuously, even when it is not actually heating the air being produced, thus blowing cold air. Changing it to “auto” will make sure the furnace only blows when it’s really heating the air to keep your home warm and comfy.

 

  • Air Filter

 

The majority of air filters need to be changed monthly to prevent them from becoming dirty and clogged. If they aren’t swapped out often enough, the soiled air filter may impede airflow into your furnace. If this occurs, it can overheat your equipment, causing the system to stop heating as a safety precaution.

 

  • Duct Work

 

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