Why Your Furnace Could be Blowing Cold Air

October 21, 2016

You listen to your HVAC system kick on and you’re anticipating a comfortable blast of warm air, but instead all you feel is cool air blowing. That’s not what you want in freezing temperatures!

There are a few reasons why your heating equipment could be giving off cold air. Service Experts Heating & Air Conditioning is here with some of them to help you locate the problem.

 

  • Thermostat

 

It might feel 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 furnace will blow continuously, even when it is not actually heating the air coming out, thus blowing cold air. Turning it to “auto” will make sure the furnace only blows when it’s actually heating the air to keep your home warm and cozy.

 

  • Air Filter

 

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

 

  • Duct Work

 

If your duct work includes leaks, connection issues, or was not designed correctly, it could allow warm air from the furnace to escape out. This would not only cause your furnace to produce cold air, it could seriously run up your heating bills since your furnace is heating non-living space, and will have to work harder to keep your home comfortable.
