Why Your Furnace Could be Blowing Cold Air

October 21, 2016

You listen to your heating system kick on and you’re expecting a comfortable blast of warm air, but instead all you feel is cool air blowing. That’s no good in freezing temperatures!

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

 

  • 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. Make sure the system is set to “auto and not “on.” If the thermostat is set to “on” then your heating system will blow constantly, even when it is not actually heating the air coming out, 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 cozy.

 

  • Air Filter

 

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

 

  • Duct Work

 

If your duct work contains leaks, connection problems, 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 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.
