thanks a lot. that's what I planned. However, still concern waste the flow since aircon facing only 3m flow whereas MHI flow can do 15m airflow. The bed is not like that in middle, I plan to sleep facing door liao to save space biggrin.gif

Facing door is incorrect lah, later you have more dream than you sleep well

Cause bad FS

Normally how they gorek the lobang for piping etc? How big a hole do they need to make? Will it be a big mess with dust everywhere?

They use a drill machine to hack off the walls, for sure is everywhere dust & flying dust too.

A disappointing and frustrated day.

Today the contractor come my house to install my ME aircond, suppose i should be very happy on that, however is a nightmare for me.

My house aircond copper was concealed one, is a 0.6mm thickness pipe that suitable for RA410 gas. However due to not long enuf, they have to extend the copper pipe by welding on the existing pipe.

One thing they really surprise me was how they test the concealed pipe whether block or not is by blow the tube using their mouth ohmy.gif I really not confident for the method they used, i suppose they are better way to test it. So they continue to weld the pipe and install in door and out door unit. After they welded and bend the pipe, they not even test it again. So, i have nothing to say but 'trust' them.

Upon finished installation, turn ON the aircond, i felt very weird, the coldness is not what i expected, is just slightly colder than ambient despite they set 16'C on 1st run, so they told me run it for 1 hour only turn OFF. They check the aircond (both in door and out door) is running then they just finished the job and go back. After they back, roughly 15 minutes, i still not feel the coldness that suppose to be. I sense something wrong there, so i check the outdoor unit, i saw the fan turn OFF itself after 2-3 minutes run. When the fan is running, i check the air blow out is not hot at all, is just at ambient temp, so i suspect the compressor is not working at all.

I called back that contractor immediately, they promised settle for me by today. After 2 hours they came back and check for me. They said the copper pipe is OK (I dun know how they check without dismantle anything), then wiring OK. They check the compressor gas pressure and everything, can't find the root cause. Then they called to their boss, their boss just order them 'remotely'. That time adi 7:30pm, i adi cooked my meal so i just have dinner with my wife in the dinning room, after i go out to see again. WTF, they open up my outdoor unit and i saw they spray water into the unit. I ask them what problem, they said the compressor motor is too hot so it cut off itself, the gas inside is low, and due to compressor cut off, they can't pump in the gas, so they spray water to cool down, hopefully can pump in the gas when the compressor start running. I really speechless at that moment. They are just electrician, not ME service man, and they are not open the unit with proper procedure, out of 4 screw on the grill panel, they just open 2 of them and pry off the casing at one end to check, it made a big dent on the casing and grill, really heart breaking.

The outcome is they have no idea how to fix it, and said it need to wait for ME to check, if is not ME fault, they will only check the piping again.

I'm really angry with them now, no matter the unit got problem or not, i won't accept that outdoor unit anymore, instead i will ask for a replacement for that. vmad.gif Now the aircond is installed but i can't use, how frustrated for that.

Anyway, the good news is, the aircond total price is 1.9k, and i only paid RM100 for deposit only. If they really don't want to replace a new unit for me, I WILL NOT PAY THE REST TO THEM. shakehead.gif

Using mouth to blow are the normal work they do. Because they have the sensor(if blocked, it can't blow through).
But after extending the pipe with welding but never blow again are wrong.

The contractor dun have exprience at all.

Can be use gas to blow in the copper before they lock the nuts

That is depend the condition

1. Like bungalow type can place anywhere as you like.
2. Apartment only at Aircon leadge
3. Terrace house only front or back
4. Contractor wanna save copper pipe then just place side by side will do.
5. In M'sia really unsafe cause everyone can steal the outdoor unit as well

Too sad the majority technician quality in Malaysia really suck, really really suck. Technician in other country need at least diploma for that, but here, those with low education/with every subjects gred F can be declared as 'electrician'. Sorry if anyone here got offended.

The boss that i speak through phone is nice manner, everything OK. But their workers are just pure teenage bastard.

Put the outdoor unit at floor and sit on top of that without my permission, even when i'm around they saw nothing.
During installation, only 2 out of 4 is work for that, but i can see they have no experience at all. That just half play half work, not serious at all.

From my point of view, those guys are just a teenage that can't study well and been kicked out of further education kind of ppl. No knowledge, but come to install stuff that need high technical knowledge, when problem happen, they only know dismantle this and that to rework/recheck. Sei sohigh, i don think those guys will have any bright future.

I previously have bought my TV and washer from the same shop, that's why i bought the aircond from them this time.

But obviously the contractor for aircond is different from last time (i dun think TV and washer need contractor/electrician for that), and this one is pure bastard.

Nowadays weather hotter than b4, that is why have many unprofessional come in town to do sub-Con and engaged cheap was learning stage to serve you guy.

In JB have lot of fully Aircon shop seldom got it happen, especially Eletronic shop will do it such thing

Yesterday that guy told me compressor got run, but cut off due to too hot, and the gas level inside is low.

For the ppl that got some sense on aircond system will know this either due to compressor run out of gas (due to piping leakage) or the piping is bend and dented so the pressure is too high due to restricted flow. Unless i really fucking unlucky to get a lemon unit which i believe the chance is low. That's why i almost 100% confirm something is wrong in during installation, and the most suspicious one is the piping.

I asked him piping ok or not, he said: I check adi no leak no bend...WTF, how do you know there is no leak without leak test..i really speechless.
*
Inverter model or gas R410a would be higher pressure just slighly lose a gap can be leak after few hours.

Choose a good workmanship is not easy btw.
Some like act pro and also expansive charge per unit too

Update for my ME aircond.

Just now ME service man checked my aircond. The conclusion they made was during copper pipe welding, the solder was went inside the pipe, eventually clogged the compressor and valve. shocking.gif They release all the gas inside and refill it, and said the gas is 'choking' inside. They said will order compressor motor and valve inside to replace, and the indoor unit cooling coil need to flush as well. They also asked me to reinstall the new copper pipe without welding. So i went to the shop that I purchased.

The boss is very kind (Maybe my face is very angry), he kept apologize to me for introduce such contractor, he said he had a meeting with the contractor boss yesterday, and they adi dismissed those guys who install my aircond that day. hmm.gif  unsure.gif He also promised the contractor boss will come himself to install for me. Then i told him the checking result by ME, and i said i can't accept repair, he promised to change a whole new set (both indoor and outdoor) for me. So let's see what happen next. Luckily i din pay them full amount that day, else i'm not sure whether they still willing to bother me or not.

Look at your case like easily case to solve... Anyone still saying ME after sales service may suck?

I never compare with other brand, solely based on what i got is good, but just too expensive.

No matter how, when i move in to the new house, the 2hp inverter i opt for living room will never be ME i think...would like to give a try to Daikin or Hitachi.

I see, should try Daikin inverter in future
