The cooling function is working well so far having used it half a dozen times or so.
I live in a 46 square metre apartment and the 4.2 kW model cools the main living room within minutes. I close the bathroom and bedroom doors(both directly off the main living area and no hallway) until the living room is sufficiently cool, then I open the bedroom door to let the cool air in if it's getting close to bed time.
The internal unit is installed in the corner of the living room instead of the middle, which would have been directly opposite.
