How Mitsubishi Ductless Systems Work


Here's How It Works

A ductless mini-split system pumps refrigerant (heated or cooled) precisely to the inside unit (wall or ceiling). Each unit has a remote to control the wireless electronic temperature system.

How a single room or space benefits from ductless:

  • Refrigerant is used for cooling or heating the air in the indoor unit.
  • Whisper quiet technology pushes the cold air where you want it.
  • A 3” opening through the outside wall connects the refrigerant and lines of the outdoor condenser to the indoor unit.
  • The outdoor condenser's futuristic heat pump technology effectively heats up or cools the refrigerant and then efficiently sends it back to the inside unit.
  • Continuous room monitoring of any changes in temperature and moves the air to any room you desire.
