i have checked a lot shops around klang, but only few shops got sell Mitsu air-cod.
ONKING quote me more expensive than ESH.
HLK only sell Mitsu Heavy Industry model.

yes, 7+5, you no need fork out any $ for repair if breakdown, include labor cost for transport & dismantle & install back.

for what i know from saleman, if only the existing warranty, they will free for repair but you have to absorn the labor cost for transport & dismantle & install back, is it right?

i'm still thinking want to extend warranty or not as both air-cond cost me rm240x2 = rm480

I think there are 2 types of Mitsubishi. One is Mitsubishi and the other Mitsubishi Industry or Engineering or something like that and they are not the same.

yup, mitsu electric and mitsu industry, both are not the same in term of quality and price. of course mitsu industry more expensive.

Confirmed my invoice does wrote GF13VC / GF18VC & GF 24VC.

Want to ask are non-inverter and inverter aircond using Same piping and wiring? Thx

different copper piping but same electric wiring.

How to confirm? Is it the size different?

same electric wiring but different copper. It might cost you a little compare to normal aircond

Not same wiring.

You need minimal 4 wires.
1 - Live
1 - Neutral
1 - Ground
1 - Control signal
1 - Control Signal secondary.

Some need 5 wires. Best is get 5 wires. My Panasonic need 4 wires, when i ask for Sharp, it need 5 Wires.

So best put 5. And if possible use all Inverter copper piping future to change A/C is much easier. I did a mistake by saving only RM 500+-, Should have use all Inverter piping. 10 Years later maybe hard to get non inverter, and got to redo piping.

usually inverter used diffrent piping, but some brand like daikin can used same piping if not mistaken. got to double check

if my house is already installed with inverter piping and wiring then can I still go with non inverter aircond?

It use thicker piping for Inverter. A/C fellow can solder a thinner copper if you want to use smaller HP / non inverter A/C.

Check with A/C installer lah. You pay them to install, you have the right to ask them question. And ask more than 2 contractor. This is how we learn.

Yupe, bro weikee correct, inverter copper piping is much thicker as compared to non-inverter. Unless your copper pipe is concealed, if not concealed one, you can change anytime in future. The A/C ppl told me conceal the drain pipe only, copper pipe can hide without conceal (according to some house structure, can hide nicely) as in the case of any problem, easier to troubleshoot.

Regarding the wiring, I didnt know Sharp has secondary control signal until I saw weikee's post, did you ask the sharp fella that secondary one used to control what?

Not sure, but is good to pull 5 wires. Won't cost much. Another method i learn from the A/C installer is use the earth wire as secondary controller wire, and use the copper pipe as Ground. So 4 wire is possible to use Sharp too.

Herm, copper pipe as ground ar? In the case of any gas leakage, then it will be troublesome lor?

Nope, cause wires also made of copper. But you plan to use inverter, just put 5 wires better.

You are correct, add on a wire from 4 wires shouldn't cost u much too.

Damn...I been told that Inverter / Non inverter copper cant be mixed, hence I didn't install Inverter version....but from above Inverter piping can use by Non Inverter???
If true...too late

Copper piping for inverter AC is slightly thicker than those for non-inverter. If you have install the thicker piping for the inverter, you could still use for the non-inverter. But not vise versa.

Yeah, My contractor showed me 2 type of copper wiring when I asked him what copper pipe he used.
A normal copper pipe around 6 feet and another copper pipe that was only 3 feet.
The 3 feet copper pipe that he was using was heavier than the other pipe double its length.
It was thicker also.
Initially wanted to install daikin inverter air cond, now due to its wiring configuration , open for suggestions
