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.

Yup, you are right on this, blow job are not a must laugh.gif
But usually some will do such blow job as to confirm no rework if have problems.
That's why I don't really like conceal piping as far as possible.

You won't know until you get cheated.
That's why if you are renovating your house, always prepare the hole for piping/wiring first.
Then install 1 air cond to test market, if ok then only install others.
But since you want people to reveal the name, in Seremban, always avoid buying appliance from Thye Hin Sermban and installer Kah Air cond.

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.

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.

Last time I also got cheated on this(from Tyhe Hin), the price of the 1.5HP air cond I bought was rm150 cheaper than others and I paid rm500 deposit for 4 air conds.
On the day I want to make full payment, they only tell me that installation are not included and it is rm180 for 1.5HP which is rm50 more expensive after installation cost than other shops doh.gif
Not to mention the installer damaged the air cond's steel pipe. Now each time I service the air cond, the installer need to weld it back cry.gif
