Five kilowatt-powered air conditioner

ARC licence number – AU54842

CLF Services are expert in installing a wide range of air conditioning units including the ever popular 5kw powered AC units. Selecting the correct size of air conditioning unit depends on a number of factors, but the room/space size to be cooled is one of the most important. At CLF Services we recommend a 5kw capacity unit for many situations where a room and a bit more space, such as an ensuite, kitchen or small lounge is required to be cooled. 

The following guide shows that a ‘medium’ room size of between 20-40sqm is best served with a 2.5kw to 5kw capacity AC unit. 

Room size Example Approx. capacity
Small (up to 20m2) Bedroom, study, small kitchen 2–2.5kW
Medium (20–40m2) Bedroom with ensuite, small lounge 2.5–5kW
Large (40–60m2) Large bedroom, mid-sized lounge, large kitchen 4–6kW
Extra large (60+m2) Open-plan areas, large lounges 5–9kW


The capacity of the air conditioning unit required to economically and efficiently cool a room also depends on whether the room or house is the room or house insulated, plus the structural components of the room for mounting the AC unit. In our deep experience in installing air conditioners, we find that 5kw units are very often the best choice for customers. This is particualry the case when weighing up the upfront costs and on-going running costs of your new AC unit.
