What Size Split System Air-conditioner Will You Need?

Calculating the correct capacity or size of an air conditioner for your home is important for several reasons. Will the reverse cycle air conditioner be installed in a living room, a home gym, theatre room, open-plan living area and kitchen, a bedroom, or a study?

The size of your room or rooms:

The larger the area, the larger the unit system capacity is required. A typical guide:

The climate

The geographical location of your home needs to be considered. Homes in Victoria have very different heating and cooling requirements to those in far north Queensland or WA for example due to differences in weather and climate.

Ceiling height

Rooms with higher than average ceilings may most likely need a higher capacity (kw) split system aircon to generate enough cool air for the room.

 Number of windows and sizes
Depending on the number and size of windows in the room, up to 40 percent of heat loss can occur, especially if windows are north or west facing.


Are the floor, ceiling and walls insulated? A well insulated room in summer will be able to keep the harsh midday heat out and the cooler air inside for much longer. In this case a smaller air conditioner may be a better option and work more efficiently in a well insulated room, costing less in installation costs.

Additional Factors To Consider

Energy Efficiency: If a split system air con unit is too large for a room, it will cool the room too quickly and then shut off, leaving the room with alternating hot and cool air. This leads to excessive energy consumption and higher electricity bills. On the other hand, if an air conditioner is too small, it will struggle to cool the room and will run continuously, also leading to higher energy bills.

Comfort: A correctly sized air conditioner will provide consistent comfort by maintaining a stable temperature in the room. If the air conditioner is too large, the room will be overly cool, while if it’s too small, the room will not be cooled enough.

Humidity Control: An air conditioner works well to help control humidity levels. A correctly sized air conditioner will remove the right amount of moisture from the air, preventing the growth of mould and maintaining a comfortable level of humidity.

Durability: Running a split system air conditioner that is too small or too large for the space can put a strain on the unit and reduce its lifespan. The correct sized air conditioner will run efficiently, which will not only help you save money on your power bills but also prolong the life of the unit.
