What is a split system air conditioner?

Two units that move heat, not make it

A split system air conditioner has a wall mounted indoor unit and an outdoor unit, joined by refrigerant pipes. It is called a split because the system is split between the two.

Most are reverse cycle split systems, which run that process in either direction. That is why one unit can cool a room in summer and heat it in winter.

How a split system cools in summerHow a split system heats in winter

Inside

Heat is absorbed

The indoor unit draws warm room air over a cold coil, which soaks up the heat.

In the pipes

Heat is carried out

Refrigerant takes that heat through the wall to the outdoor unit.

Outside

Heat is released

The outdoor unit releases the heat, and cool air keeps flowing into the room.

Outside

Heat is collected

The outdoor unit collects heat from the outside air, even on a cold day.

In the pipes

Heat is carried in

Refrigerant takes that heat through the wall to the indoor unit.

Inside

Warmth is released

The indoor unit blows room air over the warm coil and back into the room.

Benefits of a split system air conditioner

Heating and cooling from one unit

Cool the room now, and the same reverse cycle split system will heat it when winter comes.Heat the room now, and the same reverse cycle split system will cool it when summer comes.

Lower upfront cost

With no ducts or ceiling work, a single split system costs far less to install than ducted air conditioning.

Room-by-room control

Each unit has its own remote and thermostat, so you only run the rooms you are using.

Efficient to run

Inverter compressors speed up and slow down to hold the temperature instead of switching on and off.

Quiet indoors

The compressor sits outside, which makes a wall mounted split system a good fit for bedrooms.

Where it suits

Where a split system works best

A split system suits any space you want to heat or cool on its own. These are the places we install them most.

Bedrooms

Quiet, with a sleep mode and a timer, and cheap to run for one room overnight.

Typical size: 2.5 kW

Living areas

A larger unit with wide airflow covers the room everyone uses, kitchen included.

Typical size: 5 to 8 kW

Home offices

Heat or cool the room you work in during the day and leave the rest of the house off.

Typical size: 2.5 kW

Apartments and units

No roof space is needed. The outdoor unit sits on a balcony or a wall bracket.

Typical size: 2.5 to 5 kW

Granny flats and extensions

Add heating and cooling to a new space without touching the system in the main house.

Typical size: 2.5 to 3.5 kW
