To victorkk,

1) Higher airflow, yes, will help to cool down the room faster but you need to note the BTU too which is more important.
2) The running current of the indoor unit doesn't matter much, its the outdoor unit that matters.
3) You can switch on all units, just that the total btu is limited by the compressor btu output.
4) This is a 5 ticks model, will save quite a fair bit of energy if your usage if high.

You are right. i took the reading as max air flow.

How to calculate the efficiency of the main compressor? Is it output(KW) / input(KW)? Its very tiring to google from many websites to piece together all the information.

@galaxynote: is starmex 5 tick system very quiet? the compressor will be just outside my master bedroom, don't want a "generator" running. haha..
maybe this post in the blog will help you? (i guess this is Terumo blog?)

From the post,9k BTU is suffice for All HDB Bedroom size and 18k BTU is suffice for most HDB Living room (even 5 room flat). But if you have a lot of parties in your living room, you might consider bigger BTU FCU.

The compressor is quiet and amazingly small footprint. .only thing it is made in thailand...
Fj series is definitely one of the best!

Hello OrangePineapple!

I bought a new Mitsubishi System 3 from Newway about a year ago.

It was a SUPERB experience for me and everything has been working very well.

I found them from online research and also recommendations from other users in this forum.

If you are look for a reliable and trustworthy company, I think you should really check out their services.

I am certain Newway is a safe bet as even my husband (a very very picky man) was equally impressed with their services!
I use Newway to replace my aircon system in Nov 2015. They took 1.25 days to change aircon, piping and trunkings. Up to now, no problems encountered. Highly recommended.

Confused about what is the best piping .. is it those black styrofoam like better or those white ones with a plastic covering? Anybody kind to share which model is the best copper piping and insulator?

To hahnhahnhahn,

Armaflex is the most commonly used, should the the black rubber type.

Sys 2
1. Daikin $2180 - 3 ticks
2. Mitsub heavy industries $2070 - 4 tick
3. Mitsub starmex $2290 - 2 ticks
4. Pana $2290 - 3 ticks
5. Panasonic $1980 - 2 ticks

Materials they using 13mm drainage pipe, 3/8 insulation and 23swg copper pipe. All material are the most basic type.

Above I saw at audio house bendemeer 2 days ago. They give vouchers but can only can deduct $20 for $100 purchases of other selected products.

Hope it helps

I installed a Panasonic Sys 2 for about $2300. It's the new model with 4 ticks.
One 9k and one 12k unit.
Look for Lerwick Services.

Your system 4 configurations are underpower.If 4 FCUs were to turn on together, the temperature is not cold. Around 23+-. You will see the underpower during hot day.

I just installed A4UQ30GFA0. It is a high capacity ACU. Just $200+. But you have to check the access route to see whether any obstruction or not.
