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

It's like using a bigger engine in a small car.
The fuel consumption may not be higher since the engine takes less effort to propel the car.

Pray hard it not PCB. I tio PCB before, 2 located inside compressor unit need to change oso the fan motor, cause the repairman said motor might already spoil and will short the new boards if don't change causing more trouble and $$$ to come replace again. Prepare $850 inclusive labor. And the repairman advice us don't off the aircon power switch since we using it everyday. Eversince, no more hardware components problem till we change to new aircon this year.

That was in 2007. Mine was installed in 2005, that's time still new using inverter technology.[/QUOT

Is the aircon power switch means the isolator that is located at the compressor?

3 things to note,

1) Having 12k instead of 9k means nothing if your run all 3 fcus at the same time, cos your compressor cannot handle 36k btu/hr load.

2) Do note that oversizing your fcu will lead to higher-than-ideal humidity level.

3) 12k fcus do use a bit more electricity due to the larger fan than the 9k counterpart, but I'd say it's minimal. The bulk of electrical consumption comes from compressing the refrigerant, not operating the FCU.

Just curious, How will it feel if it's higher than humidity level?

High humidity is characterised by sweat staying on the skin. Becos the air is saturated with water, sweat cannot evaporate off the skin. This is basically what we feel in singapore after the rain stops and the sun comes out. You sweat but it doesn't evaporate.

It is perhaps easier for us singaporean to distinguish how mid humidity feels like, which is basically how you feel in most (properly sized) airconed locations.

So if the humidity is not reduce enough, basically you feel cool, but the sweat stays on your body. That's akin to the feeling of night time after a downpour.
