Why Your Furnace Could be Blowing Cold Air

October 21, 2016

You listen to your HVAC system turn on and you’re expecting a cozy 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 Heating & Air Conditioning is here with some 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 and not “on.” If the thermostat is set to “on” then your heating system will blow continuously, even when it is not actually heating the air being produced, 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 cozy.

 

  • Air Filter

 

The majority of air filters need to be changed once a month to avoid them from getting dirty and clogged. If they aren’t replaced often enough, the dirty air filter may impede airflow into your furnace. If this happens, it can overheat your furnace, causing the furnace to stop heating as a safeguard.

 

  • Duct Work

 

If your duct work includes leaks, connection troubles, or was designed incorrectly, it could let warm air from the heating system 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 heating system is heating non-living space, and will have to work harder to keep your home warm.
