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
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?

Pls go scroll a few pages in front and read. I explained pretty in-depth there.

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.
