Why Your Furnace Could be Blowing Cold Air

October 21, 2016

You hear your HVAC system turn on and you’re ready for a comfy blast of warm air, but instead all you have is cool air blowing. That’s no good in the freezing weather!

There are a few reasons why your heating equipment could be giving off cold air. Gordon's Service Experts is here with a few of them to help you find the problem.

 

  • Thermostat

 

It may sound silly, but the thermostat is where you should start. It’s the starting place for any furnace technician, too. Verify 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 isn’t heating the air coming out, thus blowing cold air. Flipping it to “auto” will make sure the heating system 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 once a month to keep them from getting dirty and clogged. If air filters aren’t replaced often enough, the dirty air filter may impede airflow into your furnace. If this occurs, it can overheat your furnace, causing the furnace to stop heating as a safety precaution.

 

  • Duct Work

 

If your duct work includes leaks, connection troubles, or was designed incorrectly, it could let warm air from the furnace to escape out. This would not only cause your heating equipment to give off cold air, it could seriously run up your utility bills since your furnace is heating non-living space, and will have to work overtime to keep your home warm.
