To duracellb,

Living room can take 22/24k btu.
The unit that you use the most often can setup as a single system.
Or different rooms that you use often to one compressor, depending on your usage.

Hi Terumo, thank you so much for advising. Benefited a lot from your sharing in this thread.

The salesman told me he upgraded free insulation to Yamato insulation from Japan(white in color, different from black one and it comes in a bag of 45metre) and 23swg copper pipe. My hubby asked why the insulation so long and the salesman say it reduce condensation and then he also ask why it is not 22swg and he explained that they might tell u they use 22 but when they install time they will bring 23 or 24 one to cut cost which makes sense becos my hubby went to see my neighbour installation last week by some contractor so he kaypoh go and ask what pipe they using and they say 22 but then no packing one lei... only got marker write 22swg.. so hubby say better use reputable company for a/c, dun want to suffer leaking problem next time. Salesman was quite sincere and honest though.

The only thing good about them is they uses Yamato insulation from Japan.
Installers are from country B********h. 2 works on my installation. Claimed to hv 6-7 years exp. Squeezed 2 copper tubing to 1 insulation beco' they cannot go thru' the wall. Finished without vacuum the piping. Surprised to see whole group of them come to meet them when done...
Now master bedroom unit having plastic cracking sound. The shop, the agent and the factory do not want to admit there is a problem. Telling me to set to 24-25 deg with med-high fan speed.

My MHI aircon broke recently after 7 years (installed in 2009).

Our service guy (Aircon Cooling) recommended a Mitsubishi Electric, while I'm undecided between these options, both are Inverter System 2 :

a) Mitsubishi Electric MXY-2E20VA / 2 X MSY-GE10VA for $2070 including installation.
This has 4 ticks (energy saving).
The service guy said this model is more quiet.

b) Mitsubishi Heavy Industries SCM45ZJ-S / SRK25ZJ-S x 2, same price as above.
This has 2 ticks.
The guy said this model has more issues with his past customers of not being cold enough, faulty spare parts, etc.

Any experience with these 2 systems? Does the ME system (2 ticks) really consume so much electricity?

I dun really like Mitsubishi starmex cos you can open the flap for cleaning but those are made of plastic so it will get loose after a period of time then will have some vibrating sound. That is my opinion.

maybe the electrical engineers here can help.

Not sure if its the compressor problem or a lack of gas.

my compressor continues running even though the fancoil is turned off. And it freezes up the external piping and the fancoil (the grey small fins behind the air filters become covered with ice).

only when i turn off the main, the compressor fan stops turning and the ice melts.

After defrosting, when i turn it on back, the air is cool and after about 30mins or so, it starts to freeze up.

possibly due to lack of gas that the compressor keeps turning or some electrical malfunction to the compressor?

tia!

Wow, I did not know LG air-con is so problematic but I never trust any Korean brands or products even though it is popular or it claim to be very good or branded, I still trust Japanese products as they have pride in whatever they produce.

Can pM me the quote you received from Toshiba Sys 4? Me too looking at it. So far, the quote I receive is $4149 (no upgrade of piping, inclusive of $200 Cap voucher and no bracket).

Deciding on whether Mit or Toshiba.
