Can't find Mitsubishi Heavy Industry air cond price that's why I ask michaellks to share.

Just get a quote from my contractor for cost of air cond installation as below:

1. Conceal and install copper piping for 3HP cassette air cond (30ft) - RM800
2. Conbceal and install copper piping for 1.5HP air cond (105ft) - RM2310.
3. Conceal and install copper piping for 1.0hp air cond (75ft) - RM1800
4. To install 1 hp air cond - RM120 each
5. To install 1.5hp air cond - RM150 each
6. to install 3.0hp cassette air cond - RM350 each.

* all these air cond are non-inverter.

What you think about this pricing? Expensive or ok? Thanks for sharing!

105ft, wow, you have a big house. Did you factor in losses? If not later you get under sized Ac, waisted the money and not cold.

You got PM

Wow. Long piping. A reminder, check your AC spec. I do not believe there is any 1HP and 1.5HP AC piping that allows you to go more than 20m. That 100 plus feet might result in compressor oil return problem and your compressor will die very fast. Capacity drop is the last thing you will want to worry.

Hey all, you may contact this contractor for Air Cond. Installation.

Nice service and also do energy saving for ur house!!!

No harm to try...

He might able to provide nice service.but how do he provide energy saving for your house by just install aircond?
Mind do share?

Right...enlighten me...tell me how an AC installer can help you do energy saving? Unless he helps you temper your meter la. Is that what you mean?

I am having a problem.

Developer had ready with the copper pipe and everything conceal in the walls....
however, I m only afford to buy two airconds at master room and living hall....

but, there there two more points at room 2 and room 3....how do you cover the piping? can i use back the gas pipe after three years or even more? if I didnt tape the holes, i afraid "lipas" will go in and block the holes in future....

so, any idea? Tq

Masking tape to tape the holes inside, and masking tape + plastic bag for outside. Can just leave it.

tq....

my wife want to seal it forever....she said not nice.....but, i want it to be kept......it is wasted if seal it forever...haha.....

U can ask your ac man to cut it short n cover with a nice pic/ drawing.
Next time u want to install ac just extend by welding the copper piping…

oic, can weld........good idea.....

What every you do, don't bend too much. It will be unusable.

thanks wv the advice...

Really sorry for the confusion. Actually I need to install 7 units of aircond : 1 2.5HP Cassette (according to my contractor, the installation cost is the same as 3HP, so, he quote me 3HP price), 3 1.5HP and 3 1HP. Very headache now. Install aircond also damn expensive!
Thank you!

Copper pipe is brazing. Not solder or weld. Dont bend it I agree. Warp the outlet with muskin tape and outdoor side put plastic bag. Get your AC installer to vacuum kao kao during installation. Just leave it there and dont cut. Poor brazing work will result in leakage. What they do in factory is that after they braze the will usually test the brazing point with a 450 to 600 psi pressure depending on pipe thickness. I doubt that your AC man can do that. Do not cut.

Oh my, you remember me back when I work in 1 of the aircon manufacturing. Yes the process of condenser(indoor) and evaporator (outdoor) is brazing the copper pipe together. Than pump high pressure air into it and put into the fish tank. Check for the bubble leakage. Than take back and repair again. Even we using this method of checking on the compressor.
