Which one is right for you?

Pick the MSZ-FX18NL if

  • it's a garage, bedroom or single room and you want the simplest install
  • you don't have attic or ceiling access above the room
  • efficiency matters most: up to 25.5 SEER2 vs 17.2

Hangs high on an outside wall; the refrigerant lines leave through one small hole behind the unit.

Pick the MLZ-KX18NL if

  • a wall unit would stand out and you want a slim unit flush with the ceiling
  • you'd rather nothing hang on the wall

Sits in the ceiling between joists, so it needs attic or ceiling access above the room.
