How Does My Furnace Work?

Arianne Large - Sunday, October 14, 2018
Without a doubt, cooler temperatures are arriving.  It won't be long until we all switch our HVAC systems to heat mode.  Have you ever wondered how your furnace works?


A gas furnace can be fueled by propane, oil, or natural gas.  When you set your thermostat to heat, the furnace's ignitor will fire up the burners.  The burners produce heat that moves into the heat exchanger.  The blower then moves the heated air through your ductwork and into the rooms of your home.


If you have an electric furnace, electricity powers heating elements which heats the air.  The heated air travels through the electric resistance coils and blower circulates the it throughout your home. 

No matter your heat source, your system will continue to run until the desired temperature set on your thermostat is satisfied.

Until we get back to our warm Carolina weather, furnace maintenance is essential.  Our Technicians will deliver the TLC that your furnace needs to reduce wear and tear to components, maintain the highest efficiency possible, catch issues before they progress into costly repairs, and ensure that all safety features are working properly. 

We hope you do not have issues with your furnace.  If you do find yourself without heat, call Helms Heating & Air Conditioning at 704-821-6255.  Our Technicians are trained to diagnose and repair all brands of furnaces.  We are available seven days a week, 24 hours per day, should your family have a heating emergency.
