| Split ACs ranges from 1.0T to 4.0T. They are split into 2 basic components i.e. the Indoor unit & the Outdoor unit. Room Unit can be installed wherever you want but in the room, whereas the condensing unit is placed outside -on a ledge or in the balcony. They are less noisy since the compressor & condenser fan are there in the Outdoor unit and more expensive than Window Acs. Splits are preferred for spaces which have no window or which require a quiet environment.
