Split Type Aircon: Which is best?

[Gumusut_Amige]

hitachi na 2hp? last research ko LG and GREE and Samsung pinaka mababa na power draw.

the logical reason why 7-11 use only hitachi a/c brand coz it's 24-hours in operation.
as per the owner statement, power consumption savings by hitachi a/c is upto 50% vs other leading brand. kaya kahit almost 2x ang acquisition unit price nya ay yan lang ang ikinakabit ng 7-11 stores.
