Why Your Furnace Could be Blowing Cold Air

October 21, 2016

You notice your HVAC system start up 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 few reasons why your heating equipment could be giving off cold air. D & K Heating Service Experts is here with some of them to help you locate the culprit.

 

  • Thermostat

 

It could seem silly, but the thermostat is the first thing you want to look at. It’s the starting point for any heating technician, too. Confirm the system is set to “auto as opposed to “on.” If the thermostat is set to “on” then your HVAC system will blow continuously, even when it isn’t really heating the air coming out, thus blasting cold air. Flipping it to “auto” will make sure the heating equipment only blows when it’s actually heating the air to keep your home warm and comfy.

 

  • Air Filter

 

Typically air filters need to be changed monthly to prevent them from getting dirty and clogged. If your filters aren’t replaced often enough, the soiled air filter may impede airflow into your heating equipment. If this takes place, it can overheat your system, causing the furnace to stop heating as a safeguard.

 

  • Duct Work

 

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