Size is the number one thing people get wrong when buying a split system. Too small and it runs flat out all day without ever getting the room comfortable. Too big and you've paid for capacity you don't need.
A rough guide
- 2.5kW — a standard bedroom or study.
- 3.5kW — a larger bedroom, a kids' rumpus or a small living room.
- 5.3kW — a typical living room or a modest open-plan area.
- 7.0kW — a large living room or open-plan kitchen/living/dining.
- 8.0kW — big open-plan spaces, or several connected rooms.
Why it's only a rough guide
Room size is only part of it. Ceiling height, insulation, which way the windows face, how much afternoon sun the room gets and whether it opens into other areas all change the answer. A west-facing living room with high ceilings and no insulation can need a size or two bigger than the same room on the shady side of the house.
