hi guys,

any possibility the conceal copper piping leak?

My bedroom 1HP ac is not cold after 2-3 weeks pump in the coolant gas.
Ask the Pana service men come check, they keep say it could be the piping leak... Is that normally for new AC set their condenser/compressor piping wont leak?

How to detect the conceal piping leak?

I have installed 7 sets of concealed piping.
Due to Budget not enuff, only getting 3 Air Cond.
The balance air cond piping not used will have ugly piping and wires dangling from the wall.
Any way or products that can cover these up ah??

Best is leave it as it is. Bending the copper pipe few time will damage it. I had this problem where one pipe was near the floor (outdoor), it was move few time for painting and cleaning. End up I have to cut entire pipe hack bit and resolder a new pipe because it was bend too bad.

Decorate it with some leaf and flower.

Pressure test @ 300psi, got result in 30 minutes

Make sure your outdoor A/C pipe is facing downward, or have a plastic bag cover it. The black thermal wrap can guide water into your room / living room (Copper pipe can too if its not seal). This happen to me when the a/c was not install. My floor in living room and bed room above the a/c pipe was wet. Scare the hell out of me, initially though it was roof leaking. Later found out the a/c pipe guide the rain water in. I cover it with plastic bag, problem solve...

Hi all

When concealing, is it a good practice to keep the copper pipe and electrical cable apart from each other ?

Usually they will put together with the big pipe, I don't it will have any problem.

1 thing I don't understand is, for old practice, I see they separate the return hot gas copper pipe from the insulate cold gas copper pipe. For logic, it is correct way.

But nowaday, the hot and the cold copper pipe is insulate together. The hot gas pipe is insulate for what? It should disipate the heat out not to insulate the heat. I try to ask them, but can't give me the answer.

I have heard from someone that it is best practice to separate the electrical wire from the copper pipe.

Thus it is better to have two separate tracks instead of one. Nevertheless all the contractors are putting all of them together of the same track.

Guys,
My new condo already have the A/C piping in place, done by my contractor. This include all the conceal & plastering work.
Now, the question is, if i buy the aircond, can i get cheaper installation charge? because normally, the installation cost will include some minimal piping e.g 10 feet.
Normally they said the 10 ft piping is free that come with the installation.

any one here have any idea on wiring,piping and installation for 2.0HP INVERTER for around 15'?

The contractor estimated me of about rm700 or more for it..

I got A/C contractor charged me RM200/unit for copper pipe and water pipe with conceal <10Feet.
I have three rooms to conceal so total RM600 paid. And living is back to back so FOC.

invertor 1hp
basic 1.5hp
basic 2hp

Anyone know the installation & conceal pricing?

Errr...got my quote at rm 1260 with below units.

inverter 1hp (piping minimum 18', drain pipe 10')
inverter 1.75hp (piping minimum 12', drain pipe 10')
non-inverter 2hp (piping maximum 3', drain pipe 15')

Price includes:-

1) Wall hacking for those lengths
2) Supply copper pipes. Inverter using 0.61mmt copper pipe. Non-inverter is 0.51mmt
3) Supply wire
4) Installation of AC

No patch up and AC buy myself.

Woww cheap leh! My quote for 1hp invertor is $380
I request for 2.5mm cable

Mine is also 2.5mm cable. My price should be fair I guess. Your 380 includes what? Hacking, piping, wire, installation?
