  • Up to 20.0 SEER Efficiency Rating
  • Pro Series™ Systems
  • Comfort Sync Compatible
  • 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 16.0 SEER Efficiency Rating
  • Pro Series™ Systems
  • Two-Stage Scroll Compressor
  • Comfort Sync Compatible
Rather than being "all on" or "all off," your cooling unit can adjust its cooling output based on conditions inside and outside your home. So you use less energy to maintain comfort.
