Why Your Furnace Could be Blowing Cold Air

October 21, 2016

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

There are a handful of reasons why your heating system could be blowing cold air. McKinley Heating Service Experts is here with a few of them to help you locate the problem.

 

  • Thermostat

 

It might feel silly, but the thermostat is the first place you should check. It’s the first place any heating system technician will check, too. Make sure the system is set to “auto instead of “on.” If the thermostat is set to “on” then your heating system will blow continually, even when it isn’t heating the air coming out, 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 comfy.

 

  • Air Filter

 

Most air filters need to be changed once a month to avoid them from growing dirty and clogged. If air filters aren’t changed often enough, the clogged air filter may obstruct airflow into your heating equipment. If this occurs, it can overheat your equipment, causing the system to stop heating as a safety precaution.

 

  • Duct Work

 

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

 

There are multiple other reasons that your furnace could give off cold air.
