Currently using Mitsubishi Inverter Starmex system 4 since 2009 replacing my 8 year old Daikin. Both brand I considered as excellent.

9x9x9x18 - configurations

My current starmex i think is the First Gen model, so far never break down. Did the usual maintenance over the years.

Moving on to my new BTO, I just purchased and installed the latest Mitsubishi System 4 starmex 5 ticks. Bought from Gain city, overall installation is fine. Some upgrades such as Armaflex, piping 16mm, copper 22. yet to move in to my new hse to test the actual power consumption.

Current config
9x9x9x24

As a heavy user, my AC is on almost 24/7 on daily basis. I hope Power consumption with 5 star ratings will help.

IMHO, its best to get a System 4 rather than a sys 3. Why? SG so hot. Living room sometimes need AC when me & wife hang around in the living room. It will be uncomfortable without AC. Pls I don't plan to install ceiling FAN. These fan won't help much to cool down the living room except blowing hot air.


I believe those that checked the first 20 pages in this thread will know the exact date I install my System 4 Starmex. Didn't expect this thread would grow to 446. hahaha

Hi peepz....

For a resale 5-room flat...
Was looking at System 5, but seem like only Toshiba has that in the market....
Is System 4 enough?
Maybe due to budget.. might go for the latter...

If any gurus here can advise would be good...

Thanks!

Not too sure, you need to check with AC repair & serving guy.

My bedroom has only 1 powerpoint. When installing the aircon will it come with additional powerpoint or do I have to source someone myself to install for me??

You can just install yourself. Go to hardware shop buy, use screwdriver open up. Close with double powerpoint. Done

Hi guys, recently I purchased a LG Non-Artcool inverter system 3, but yet to be delivered and installed:

2 x AMNC09GDBA2 (9000 BTU) - for 1 BR and 1 Study
1 x AMNC12GDBA2 (12000 BTU) - for 1 MBR
1 x A4UQ26GFA1 ( 4 ticks)

Then suddenly wife got another idea of arrangement:

2 x 9000BTU - for 1 BR and 1 MBR
1 x 12000 BTU - for living room

Living room is about 3m x 10m with no partition in between. Most activities is only at one half of the living room ie TV and sofa etc. Is 12000BTU enough to cool half of the living room with a ceiling fan? Hardly all 3 units will be turn on the same time, at most only 2 units.

Please advise. Thanks.

Looks a bit underpowered.
