Why Your Furnace Could be Blowing Cold Air

October 21, 2016

You notice your HVAC system kick on and you’re anticipating a comfortable blast of warm air, but instead all you have is cool air blowing. That’s not what you want in the freezing weather!

There are a few reasons why your heating equipment could be giving off cold air. Service Experts Heating & Air Conditioning is here with a few of them to help you locate the problem.

 

  • Thermostat

 

It may feel silly, but the thermostat is the first thing you want to look at. It’s the first place any heating system technician will check, 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 released, thus blasting cold air. Flipping it to “auto” will make sure the heating equipment only blows when it’s really heating the air to keep your home warm and comfortable.

 

  • Air Filter

 

Typically air filters need to be changed every month to keep them from getting dirty and clogged. If they aren’t replaced often enough, the dirty air filter may restrict airflow into your heating equipment. If this happens, it can overheat your system, causing the system to stop heating as a safeguard.

 

  • Duct Work

 

If your duct work has leaks, connection problems, or was not designed properly, it could permit warm air from the heating equipment 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 overtime to keep your home warm.
