Why Your Furnace Could be Blowing Cold Air

October 21, 2016

You notice your HVAC system start up and you’re ready for a comfortable blast of warm air, but instead all you get is cool air blowing. That’s not preferable when it’s cold outside!

There are a couple reasons why your furnace could be giving off cold air. Strogen's Service Experts is here with a couple 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 place for any furnace technician, too. Make sure 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 isn’t really heating the air coming out, thus blasting cold air. Changing it to “auto” will make sure the heating equipment only blows when it’s really heating the air to keep your home warm and comfortable.

 

  • Air Filter

 

Most air filters need to be changed monthly to prevent them from growing dirty and clogged. If they aren’t changed often enough, the dirty air filter may restrict airflow into your heating equipment. If this occurs, it can overheat your furnace, causing the equipment to stop heating as a safety precaution.

 

  • Duct Work

 

If your duct work contains leaks, connection issues, or was designed incorrectly, it could allow warm air from the heating system to leak out. This would not only cause your heating system to give off cold air, it could seriously run up your utility bills since your heating equipment is heating non-living space, and will have to work overtime to keep your home warm.
