Why Your Furnace Could be Blowing Cold Air

October 21, 2016

You listen to your HVAC system turn on and you’re anticipating 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 couple reasons why your heating equipment could be putting off cold air. Teays Valley Service Experts Heating & Air Conditioning is here with a few of them to help you find the issue.

 

  • Thermostat

 

It might seem silly, but the thermostat is the first thing you want to look at. It’s the starting place for any furnace technician, too. Verify the system is set to “auto instead of “on.” If the thermostat is set to “on” then your furnace will blow constantly, even when it isn’t heating the air being produced, thus blasting cold air. Changing it to “auto” will make sure the heating system only blows when it’s actually heating the air to keep your home warm and comfortable.

 

  • Air Filter

 

The majority of air filters need to be changed every month to prevent them from becoming dirty and clogged. If air filters aren’t replaced often enough, the soiled air filter may obstruct airflow into your furnace. If this occurs, it can overheat your system, causing the equipment to stop heating as a safety measure.

 

  • Duct Work

 

If your duct work contains 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 furnace to produce cold air, it could actually run up your energy bills since your furnace is heating non-living space, and will have to work harder to keep your home warm.
