Why Your Furnace Could be Blowing Cold Air

October 21, 2016

You hear your furnace turn on and you’re expecting a comfortable blast of warm air, but instead all you feel is cool air blowing. That’s no good when it’s cold outside!

There are a few reasons why your heating system could be giving off cold air. Fras-Air/General Service Experts Heating & Air Conditioning is here with a couple of them to help you detect the culprit.

 

  • Thermostat

 

It could sound silly, but the thermostat is the first thing you want to look at. 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 heating system will blow constantly, even when it isn’t heating the air being produced, thus blasting cold air. Turning it to “auto” will make sure the heating system only blows when it’s actually heating the air to keep your home warm and comfy.

 

  • Air Filter

 

The majority of air filters need to be changed monthly to keep them from becoming dirty and clogged. If they aren’t changed often enough, the soiled air filter may impede airflow into your heating equipment. If this takes place, it can overheat your equipment, causing the furnace to stop heating as a safeguard.

 

  • Duct Work

 

If your duct work has leaks, connection issues, or was not designed properly, it could let warm air from the furnace to escape out. This would not only cause your heating equipment to give off 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 at the desired temperature.
