Why Your Furnace Could be Blowing Cold Air

October 21, 2016

You hear your heating system turn on and you’re ready for a comfortable blast of warm air, but instead all you get is cool air blowing. That’s not what you want in the freezing weather!

There are a few reasons why your furnace could be blowing cold air. Service Experts Heating & Air Conditioning is here with some of them to help you find the problem.

 

  • Thermostat

 

It might seem silly, but the thermostat is the first place you should check. It’s the starting place for any furnace technician, too. Confirm the system is set to “auto as opposed to “on.” If the thermostat is set to “on” then your heating system will blow continuously, even when it isn’t heating the air being released, thus blowing cold air. Turning 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

 

Most air filters need to be changed every month to avoid them from getting dirty and clogged. If your filters aren’t changed often enough, the dirty air filter may impede airflow into your heating equipment. If this happens, it can overheat your equipment, 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 furnace to seep out. This would not only cause your heating equipment to give off cold air, it could actually run up your heating bills since your furnace is heating non-living space, and will have to work more to keep your home comfortable.
