Why Your Furnace Could be Blowing Cold Air

October 21, 2016

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

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

 

  • Thermostat

 

It might sound silly, but the thermostat is where you should start. 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 is not actually heating the air being produced, 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

 

The majority of air filters need to be changed once a month to keep them from growing dirty and clogged. If they 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 furnace 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 heating system to leak out. This would not only cause your heating equipment to produce cold air, it could actually run up your energy bills since your heating system is heating non-living space, and will have to work harder to keep your home warm.

 

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