Frequently Asked Questions

They get the name “split system” because they have two main components:

• The external unit including the condenser and compressor
• The internal unit including the evaporator

Split systems work by transferring hot and cold air from one place to the other.

Put very simply, the compressor pressurises refrigerant gas, which acts like a sponge, absorbing heat from the inside moving it outside whilst absorbing cool air from the outside transferring it inside.

We can help you choose the right size air conditioner for your home or business in order to effectively cool a room while minimising costs.

Splits come in a wide range of sizes and are often measured in terms of their power (kW or HP).  The type of system that you will need depends on the area that needs cooling.  Small rooms tend to only require a 2.5kW unit; however larger areas, such as a living room, might need an unit between 5.0-8.0kW.

There are other factors that must be taken into consideration when choosing a split system: location of the room (e.g. north facing), ceiling height, amount of windows, building materials, etc.

As a starting point you may use the table below, but we recommend you talk to one of our expert technicians to help correctly size your next split system.
