Why Your Furnace Could be Blowing Cold Air

October 21, 2016

You notice your furnace turn on and you’re ready for a cozy blast of warm air, but instead all you feel is cool air blowing. That’s not what you want when it’s cold outside!

There are a few reasons why your heating system could be putting off cold air. Service Experts Heating & Air Conditioning is here with some of them to help you detect the issue.

 

  • 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 instead of “on.” If the thermostat is set to “on” then your furnace will blow continuously, even when it isn’t heating the air being produced, thus putting off cold air. Turning it to “auto” will make sure the furnace only blows when it’s truly heating the air to keep your home warm and comfy.

 

  • Air Filter

 

Most air filters need to be changed monthly to prevent them from getting dirty and clogged. If they aren’t replaced often enough, the soiled air filter may obstruct airflow into your furnace. If this happens, it can overheat your furnace, causing the equipment to stop heating as a safety precaution.

 

  • Duct Work

 

If your duct work contains leaks, connection problems, or was designed incorrectly, it could let warm air from the furnace to seep out. This would not only cause your furnace to blow cold air, it could actually run up your utility bills since your furnace is heating non-living space, and will have to work overtime to keep your home warm.
