Find The Right Size A/C For Your Room
Finding the right air conditioner depends on numerous factors including room size, ceiling height, insulation, size of windows, level of sunlight and more. Below is an approximation of required cooling and heating capacities for different room sizes.
If you wish to purchase online now to take advantage of a limited time sale, but are unable to determine the correct size using the guides below, simply mention you would like a room size assessment at checkout - if a different size is needed we will happily assist with up-sizing / down-sizing*
The cooling and heating capacity of an air conditioner is measured in kilowatts (kW).
2.5 kW RANGE
SUITABLE FOR ROOMS APPROX 10 – 25 SQ METERS
Bedrooms, Studys, Small lounges, Small kitchens, Small offices.
SUITABLE FOR ROOMS APPROX 25 – 35 SQ METERS
Bedrooms, Bedrooms with ensuites, Studys, Small lounges, Mid-sized kitchens, Small rooms with high ceilings, Offices.
5 – 6kW RANGE
SUITABLE FOR ROOMS APPROX 35 – 60 SQ METERS
Large bedrooms, Mid-size lounges, Large kitchens, Mid-sized rooms with high ceilings, Medium offices.
7 – 8kW RANGE
SUITABLE FOR ROOMS APPROX 60 – 80 SQ METERS
Large lounges, Large open plan areas, Small shops, Large offices.
|Room Size m2||Capacity - Cooling (C)/Heating (H)|
|3.0m x 3.0m = 9m2||2.5KW(C)/3.2KW(H)|
|5.0m x 5.0m = 25m2||3.5kw(C)/3.7KW - 4.3KW (H)|
|5.5m x 5.5m = 30m2||3.5kw(c)/3.7KW(H) - 5.0KW(C)/6.0KW(H)|
|6.3m x 6.3m = 40m2||5.0KW(C)/6.0KW(H) - 6.0KW(C)/7.2KW(H)|
|6.7m x 6.7m = 45m2||6.0KW(C)/7.2KW(H) - 7.1KW(C)/8.0KW(H)|
|7.1m x 7.1m = 50m2||7.1KW(C)/8.0KW(H) - 8.0KW(C)/9.0KW(H)|
|7.7m x 7.7m = 55m2||8.0KW(C)/9.0KW(H) - 9.2KW(C)/10.0KW(H)|
* This table is only a general guide to the heating and cooling capacities of air conditioners across a range of brands that takes into consideration the spectrum of standard environmental conditions of various room sizes.
For more complex installations a heat load calculation should be performed. A heat load calculation comprises of many factors such as size of area, size of windows, roof type, building material, whether there is insulation, external shading or internal shading etc. Incorrect sizing will mean inadequate cooling/heating.
