TYPICAL INVERTER SYSTEMS make changes in 7Hz 
increments allowing the unit to run at variable speeds, 
delivering a more precise heating-cooling solution.
CONVENTIONAL SYSTEMS run at a single capacity, 
turning on and off to reach the desired set point. 
This means they run at full speed each time, resulting 
in high energy consumption.
TWO-STAGE AIR CONDITIONERS won’t significantly reduce 
your energy use. These units only run at 2 speeds, 50% and 
100%, also resulting in high energy consumption.
