Types of system

The right unit for the room

We'll recommend the type that suits your space, budget and how the room is used.

Wall-mounted split

The most popular choice for bedrooms, living rooms and offices. One indoor unit on the wall, one small unit outside.

Multi-split

Several indoor units running from one outdoor unit, so you can cool two to five rooms with less on the outside wall.

Ceiling cassette

Sits flush in a suspended ceiling and spreads air four ways. Ideal for offices, shops and open-plan spaces.

Ducted

Hidden above the ceiling with only slim grilles on show. A clean look for homes and commercial fit-outs.

Room size guide

What size air conditioner do I need?

Air conditioners are rated in kilowatts (kW). Too small and it struggles on hot days; too big and it wastes energy. Use this as a starting point.

Room sizeTypical roomUnit size
Up to 20 m²Small bedroom, box room, small office2.0 kW
20 – 25 m²Double bedroom, study2.5 kW
25 – 35 m²Living room, large bedroom3.5 kW
35 – 50 m²Open-plan lounge, small shop or office5.0 kW
50 – 60 m²Kitchen-diner, larger office6.0 kW
60 – 70 m²Large open-plan space7.1 kW

Based on a standard 2.4 m ceiling and an average room. South-facing rooms, conservatories, kitchens and busy offices usually need more. We confirm the right size at your free survey.
