Why Your Furnace Could be Blowing Cold Air

October 21, 2016

You notice your HVAC system kick on and you’re anticipating a comfy blast of warm air, but instead all you have is cool air blowing. That’s not preferable when it’s cold outside!

There are a few reasons why your furnace could be blowing cold air. All American Air Service Experts is here with a couple of them to help you locate the problem.

 

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

 

  • Air Filter

 

Typically air filters need to be changed monthly to keep them from growing dirty and clogged. If your filters aren’t changed often enough, the soiled air filter may impede airflow into your heating system. If this happens, it can overheat your furnace, 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 furnace 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 overtime to keep your home at the desired temperature.
