A wall split system is a popular air-conditioning choice for many Australians. The indoor unit is mounted on a wall in the room or living space that is to be air-conditioned and attached to an outdoor unit. MHIAA’s range of quality inverter wall splits includes capacities as small as 2.0kW and as large as 9.2kW. You’ll be sure to find a unit to suit the room or living space you need air-conditioned.
