its Starmex MXY3A28VA. just installed for 1mth + only.
How bout all indoor units for 3 was the same?
I meant indoor model such as GE10 or 24VA?
Either all 3 units are blinking?

If 3 units blinking that meant gas leakage.

MSYGE10VAR2, it was working until a power surge occurred after turning the circuit breaker on again and oning the aircon in less than 5 mins, the top indicator light would be blinking constantly. all 3 units also top light blinking.

Call back to the shop and arrange technical and check for you, most likely gas all gone.

Gas leakage due to lack installer.
No gas at all, so you won't feel cold anymore and the signal sign for blinking and tells you needs to check it out.

Hello all,

In urgent need to install a/c in my house.

I have read the thread and I am still trying to figure out which brand and models to choose from.

Can I have some recommendations for system 3 with good energy efficiency at a more economical price?

Thanks a lot in advance.

Hi Experts,


Need urgent advice on sys 4 installation, my old sys 3 has problem need replacement

So far I have checked on starmex sys 4 & did on-site survey by Star Cool (Aron/Ah boon), this is the quotation, seems good deal?

Starmex old: $3850nett

- Mitsubishi Electric inverter system 4 MXY4A28 / MSYGE18VA + MSYGE10VA X 3 (18kbtu + 9kbtu X 3)

Starmex new: $4550nett
- Mitsubishi Electric inverter system 4 MXY4G28 / MSXYFJ18VR + MSXYFJ10VR X 3 (18kbtu + 9kbtu X 3)

optional stainless steel bracket at $150 nett

- 1/2 inch Armaflex class "O" insulation
- G22 copper pipe
- 16mm drainage pvc pipe
- Keystone Cable (made in singapore)
- free 2 trips installation
- free dismantle & disposal of old air-con
- One year warranty for worksmanship & air-con equipments. Five years warranty for compressor

* Free Site Survey
* Special coordinating work between us and customer’s contractor
* Special appointed installation team
* Special supervising work by head of installer

Got few questions and hope experts can help provide advice;

1) Art Cool reviews seems satisfactory except maintenance issue due to design can incurred extra charges?

2) Daikin Silver Envi seems new? Can't find any reviews and mor energy saving then Starmex. COP is Daikin 4.2 vs Starmex New I duno which COP should look for; full load, part load or weighted and higher count is better?
Starmex new annual energy/cost is higher den Daikin.

3) Advisable to source for Starmex old- Zen series? Tried asking Aron/Ah boon, was told stopped production so bal on market is old units they didn't even bother to source & quote.

4) Based on my understanding; Starmex old vs new, it's not necessary that new is more energy efficient & cost savin since there is a Lock limitation of 8.5amp that applies to all AC brand unless unlocked. Hence new energy savin units might not be as cool (lower energy trade off coolness) and hence not as energy saving as projected??

5) Any other reputable installers to recom? Star Cool seems gd but response is really slow and seems to strongly promote Starmex

Many thanks in advance!

Hi all,

is this worth it for Daikin 9000 Btu system 3?

FTKS25DVM x3 + 3MKS71FSG for $3200?

Also is this combination good for energy saving?

Sorry am a noob here.

Daikin seen like only single split only
You can check on thier website as well

ME Starmex New vs Old model.
Both are good, if you concern using more than 8 hrs daily per 3 units should take the new one.

From the specs of 8.5A still far away from the standard capacity of BTUs.

Old more are good like don't have minor issue at all.
Just slighly lower capacity BTU if you wanted to turn on all at same time.

Energy saving 5 ticks should be the right choice

Hi,

my system 3 air-con (close to 10yrs), have some water droplet formed at part of the trucking at the room (nearer to compressor). My regular air-con service man said that there is problem with the insulator but don't advice changing as it is not cost effective and the problem may come back after 3-4 mths. He recommend us to buy a new air-con system.

Need expert advice here ,although the problem is not that serious yet, as it is not really leaking.

Outlet pipe can be solve, you can self check and open out trunking cover then press on Cooper pipe insulation n see wether is insulated condensation?

If yes then change new will do.
Once the copper pipe insulation condensation an issue could be nothing to solved.

Hello, may i check which configuration did you guys choose to run the trunking? Outside the room, or inside the room/hidden behind the wardrobe? Which is better? I'm in a deciding dilemma of running the trunking.

Outside room: Easy/cheaper for repair/maintenance in future
Inside room: More neat and tidy
(No offense to anyone choosing either way)
