High Efficiency Comfort Systems

4MXW8 Single Zone 22 SEER Mini-Split Heat Pump

This indoor ductless heating and cooling unit works as part of a ductless mini-split or multi-split system. Mounted on the wall, this ductless unit offers flexible, high-efficiency heating and cooling for precise comfort without the ductwork.

  • Quiet Design Specially designed air vent efficiently reduces operation noise, as low as 23 dB.
  • Turbo Function/Fan Speed High speed operation quickly reaches desired temperature. Seven fan speeds from Quiet to Turbo maximize your comfort experience.
  • Sleep Mode Function Temperature rises/falls automatically to maintain room comfort and save energy while you sleep.
  • Auto Clean/Triple Filtration Fan runs when unit is stopped to reduce moisture and inhibit the development of bacteria, and the triple filtration further cleans the air that you breathe.
  • Anti-cold Design To prevent blowing cold air directly to the room, air is pre-heated during heating operation.
  • Timer Operate the unit automatically only when you want by setting the timer.
  • Wireless remote control Each ductless heating and cooling unit is controlled with a wireless remote control (purchased separately) so you can easily control your system from anywhere in the room. The "I feel" function enables the system to sense temperature at the remote control, rather than a thermostat.
  • Memory function In case of power loss, the system will restart in the previous operation mode without the need to reset the system.
