Ytd go GC Sungei Kadut get MHI sys 3 with free upgrade 9k to 12k BTU.

SCM60ZJS - 3XSRK35ZMAS
Upgrade 1/2 class 1 insulation
Upgrade copper piping 23 to 22
Dismantle of old unit

2799 plus upgrade 117 = 2916

Is it a good deal? 12K BTU increase electric bills? Just realise the invoice nvr state the warranty how many years my bad
mhi is 3 tick so power consumption for its btu is quite ok liao

12k btu means cool the room faster and since its is inverter means after the room reach certain temp it will run low power.

compare to those 9k btu will take a longer time to cool the room. as it constantly using low power to cool the room
