Split system air conditioning consists of two main components: an indoor unit that contains the evaporator coil and an outdoor unit that houses the compressor and condenser coil. These systems are popular for their efficiency, quiet operation, and flexibility in zoning. The indoor unit is typically installed high on a wall and blows cool air into the room, while the outdoor unit expels hot air outside.

Split systems are suitable for both residential and light commercial applications, providing customised comfort levels in different areas of a building. Their ability to cool or heat spaces efficiently while remaining inconspicuous makes them a preferred choice for many consumers.
