The ENERGY STAR program is a joint program of the U.S. Environmental Protection Agency and the U.S. Department of Energy helping us all save money and protect the environment through energy-efficient products and practices.
Rather than running at one or even two speeds, the 20LX Inverter-Driven Scroll Compressor changes its speed in small, precise increments and adjust cooling up and down like a dimmer switch. So temperatures are held exactly where you want them, even in extremely hot weather.
SEER (Seasonal Energy Efficiency Ratio) rates the energy efficiency of your cooling equipment. The 20LX is up to twice as efficient as common legacy systems. The higher the SEER rating, the more efficiently your unit operates, saving you money on utility bills.
Allows heat pumps to enter defrost mode without excessive noise. Since refrigerant pressure is allowed to equalize before the switch, the heat pump can dissipate performance-robbing frost and ice quietly.
Armstrong Air coils feature rifled tubing to enhance refrigerant flow, while lanced coil fins increase surface contact between metal and air for maximum heat transfer and efficiency.
