How do electric heating coils work?
A coil is a heating element attached to the heating unit itself. The heater generates an electric current flowing into the coil, which transfers the electric energy into heat energy. It may be directly immersed in the medium to heat it or radiate heat through an open space.
How often should furnace coils be cleaned?
Cleaning the Coils
Ideally, air conditioning maintenance should be performed twice a year, though once is sufficient for some systems. Between visits, the condenser coils can be cleaned by removing large debris and rinsing the coils with a hose, after shutting the power off.
