It is important to chose the correct size of air conditioner for a room. Too small and the air conditioner will be working too hard, the room will not be cool enough and you may get condensation problems. Too large and your air conditioner may be constantly switching on and off.
This calculator is to help you decide what size of air conditioner you will need.

Different brands of air conditioners use different ways of indicating their size, for this reason 3 different size equivalents are given:
- PK (Dutch for Horse Power or HP) which is the common sizing of air conditioners in Bali.
- BTUs (British Thermal Units) the common sizing used in America.
- The electrical power rating in watts (this is input watts not output watts).
The better a room is insulated the less air conditioning you will need. As a rough guide:
- A well insulated room might have thick solid walls, an insulated ceiling, close fitting doors and few or double glazed windows and not many people in it.
- An medium insulated room might have solid concrete walls, close fitting doors, an insulated roof and few standard windows.
- A poorly insulated room might have large window area, poorly fittng doors, a roof or walls that give off heat or a lot of people in it.
