ME also not quiet 28dB then what? better wall fan 

never look at inverter model coz no money. have they got the low watt series 320watt for inverter?

no balcony.basically a very flat house

but how?

are they going to take out the window then drill holes for L metal compressor mounting thingy then how are they going to bolt/screw the compressor at bottom of the L metal compressor mounting thingy idk whats the name lel.

i wanna believe if this is happening in PRC  

but is Malaysia also practice this way ?

most important is have a window that can climb out
if all grill up then sorry, cant install

same here , my cousin say service for ME air cond is hard and spare part costly too in malaysia

Gosh..Pana, Sharp, ME....dilemma again now 
Previously tod plan to get ME but after see hard find sparepart?

this post is useful for me ...

will survey for ME and Hitachi price ..since the price is about the same ...

those aircon manufacturer do make their own stress test and QC QA etc ..even durex also done their own stress test on the condom..... 

100 out of 10k unit might fail that is why they do give warranty etc.... sony samsung do give warranty on their product , does it mean their product not good and they no confident , thats why give warranty ?

it is quite subjective to say this brand no good easy to spoil etc .... so what can we compare only the spec and quietness of the aircon....

   

Hitachi on quiet mode 19dB confirmed but their AUTO fan speed still too noisy for my liking.

I use the premium inverter AR09/12HVSDB models. Both are quiet even without activating quiet mode.

All inverter use minimal 4 wires. Live, neutral, ground, and data. Some have 2 data line. My Panasonic use 4 too.

Something new to me. What model is this? I like to download the installation diagram to study.

From http://www.mitsubishipro.com/media/214726/...h549b_12-10.pdf

page 10 - 14,  S1 = Live, S2 = Neutral, and S3 = Data/Singnal. It still have data.

From the design, it look like the ground coming from the copper pipe to the indoor unit.

test lab would have sound absorbers all across the entire room to seal off any echo. we have one here.
