Pro Series™ Systems
Pair this model with a Pro Series™ variable speed furnace and a Comfort Sync thermostat, for optimum performance. With the Pro Series, you’re in control of every aspect of your home’s climate, as well as your energy costs. Explore the Armstrong Air Pro Series™.
True Variable-Capacity Cooling
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.
Up to 20 SEER Efficiency Rating*
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.
Quiet Shift™ Technology
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.
MHT™ Technology
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.
