Calculate your room

Choose the BTU size before the brand. Too small and it runs flat out; too big and it can cycle often and feel uncomfortable. This table uses about 770–880 BTU per m² for a typical room with a 2.4 m ceiling.

Room size	Air conditioner size
10–12 m²	9,000 BTU

21–23 m²	18,000 BTU
