Why Your Furnace Could be Blowing Cold Air

October 21, 2016

You hear your furnace turn on and you’re ready for 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 couple reasons why your heating system could be blowing cold air. Service Experts Commercial HVAC is here with a couple of them to help you detect the problem.

 

  • 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 is not actually heating the air being released, thus putting off cold air. Turning it to “auto” will make sure the heating system 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 every month to keep them from becoming dirty and clogged. If air filters aren’t swapped out often enough, the dirty air filter may impede airflow into your heating equipment. 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 contains leaks, connection issues, or was designed incorrectly, it could permit warm air from the heating system to leak out. This would not only cause your heating system to produce cold air, it could significantly run up your heating bills since your heating system is heating non-living space, and will have to work more to keep your home comfortable.
