How many BTU your AC needs
Enter the room's square meters and the sun exposure: get the recommended BTU and kW.

The power depends on square meters, height, sun exposure and the people present. Too low won't cool, too high wastes energy and cycles on/off constantly.
Reference
Roughly 300-400 BTU per m²: this estimate helps you choose between models (9000, 12000, 18000 BTU…).
