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.
