Efficient comfortwhere you need it.
A wall-mounted split system is a simple and effective way to heat and cool an individual room or open-plan area. With no whole-home ductwork required, split systems provide flexible comfort for bedrooms, living spaces, home offices and more.

What is a split system?
A split system consists of two primary components: an indoor unit and an outdoor condenser. These are connected using refrigerant pipework and electrical connections.
In cooling mode, the system removes heat from the indoor area and transfers it outside. Reverse-cycle systems can reverse this process to provide heating.
