Just to correct, "the 12k btu consumes 25% more electricity over 9k btu".

That statement is false.
Hi i be using Lg fcu as sample

Cooling Capacity
Min.∼Rated∼Max. (kW) 1.45 ~ 2.64 ~ 2.99
Min.∼Rated∼Max. (Btu/h) 4,950 ~ 9,000 ~ 10,200

Cooling Capacity
Min.∼Rated∼Max. (kW) 1.93 ~ 3.52 ~ 4.02
Min.∼Rated∼Max. (Btu/h) 6,600 ~ 12,000 ~ 13,700

the kw can be abt 33% difference btw the 2 fcu,
however i understand during the idle(or i call stable) state it can be lower so the use of 25%.

correct me if i am wrong. i am eager to learn since i also getting my own Air-con soon.
