Why Your Furnace Could be Blowing Cold Air

October 21, 2016

You hear your HVAC system turn on and you’re ready for 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 couple reasons why your heating equipment could be giving off cold air. Climate Control Service Experts Heating & Air Conditioning is here with a couple of them to help you locate the issue.

 

  • Thermostat

 

It could sound 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 as opposed to “on.” If the thermostat is set to “on” then your HVAC system will blow constantly, even when it is not actually heating the air coming out, thus putting off cold air. Turning it to “auto” will make sure the heating equipment 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 every month to keep them from growing dirty and clogged. If air filters aren’t swapped out often enough, the clogged air filter may impede airflow into your heating equipment. If this takes place, it can overheat your furnace, causing the equipment to stop heating as a safeguard.

 

  • Duct Work

 

If your duct work has leaks, connection issues, or was not designed properly, it could allow warm air from the heating equipment to leak out. This would not only cause your heating system to blow 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 comfortable.
