Why Your Furnace Could be Blowing Cold Air

October 21, 2016

You notice your furnace kick on and you’re expecting a cozy blast of warm air, but instead all you get is cool air blowing. That’s no good in freezing temperatures!

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

 

  • Thermostat

 

It might seem silly, but the thermostat is where you should start. It’s the starting point for any heating technician, too. Confirm the system is set to “auto instead of “on.” If the thermostat is set to “on” then your HVAC system will blow continuously, 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 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 growing dirty and clogged. If your filters aren’t swapped out often enough, the soiled air filter may impede airflow into your heating system. If this occurs, it can overheat your system, causing the furnace to stop heating as a safeguard.

 

  • Duct Work

 

If your duct work includes leaks, connection issues, or was not designed properly, it could let warm air from the furnace to leak out. This would not only cause your heating system to blow cold air, it could seriously run up your energy bills since your furnace is heating non-living space, and will have to work more to keep your home at the desired temperature.
