Why Your Furnace Could be Blowing Cold Air

October 21, 2016

You listen to your furnace turn on and you’re expecting a cozy 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 putting off cold air. Service Experts Commercial HVAC is here with a couple of them to help you detect the culprit.

 

  • Thermostat

 

It may seem silly, but the thermostat is where you should start. It’s the first place any heating system technician will check, too. Verify 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 isn’t heating the air being released, thus blowing cold air. Changing 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

 

Typically air filters need to be changed monthly to avoid them from getting dirty and clogged. If they aren’t swapped out often enough, the clogged 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 has leaks, connection problems, or was not designed properly, it could allow warm air from the furnace to leak out. This would not only cause your furnace to produce cold air, it could significantly run up your heating bills since your furnace is heating non-living space, and will have to work more to keep your home comfortable.
