so u let ur main con to conceal for the 2 air cond piping?

Ya,
he quoted me 1.0 HP x 3 (RM600) and 2.0HP x 2 (RM650) all inverter.
both concealed copper pipe and outlet pipe.
and he assume worst case scenario like putting the aircon in the middle wall instead of back-to-back.

actually he just quoted me, but if back-to-back installation he said just ask the aircon shop to do it for free.

Because my living room hasn't extended now that i plan to put the aircon compressor at top of the car porch instead of in front of the main door (too hot later all the wind blow in all the hot air), and the ground floor living room is in the middle of the houseplan (probably more than 15 feet) with affected plaster ceiling and etc.
So better ask him to do it, it need lot of coordination and correct timing.
the rest master bedroom, bedroom 2 and 3 just need back to back.

Is RM 800 to lay copper piping about 20ft. Is that ok?

If 1.0HP better avoid too far, max 10 feet.

1.5 HP - How? Bocz it comes down about 6ft then to the outside another 12 ft

Are u planning to fit all the aircon compressor at the back yard top roof there?
I saw some people do that way.

yup that is the plan

I think 15 feet a bit too far for 1.0HP.
Probably go for 1.5HP for safety?

Yup i using 1.5 HP Panasonic (Non Inverter type)

1.0HP is back to back onli? for my 2 small room i put 1HP, both room got their own toilet, so i put on top of the toilet's door, so got more hacking work thr..

Ya, I just can put back-to-back enough already.
Top of the aluminium windows if you view from outside backyard can already.

Your room is the small room at ground floor? or big big one?

Master bedroom upstairs. The developer gave 15 amp wiring and PVC pipe but never give copper wiring. I extended the room so the everything kelam kabut. Now decided cheaper to just extend the developer 15 amp point to the window (conceal) and the air cond pasang like biasa. The developer pipe potong and just plaster.

my small room cant put back to back, else i save a lot d...cos thr is a beam thr..so no place to fit in the indoor unit thr......

inverter or non-inverter same price for conceal works.

workmanship quite good.

but that is penang price. so not sure about KL.

im looking for a contractor on air cond related purposes(Need quotation):

1) Uninstall 1 x AC (inverter type) from old house, and install to new house
2) Buy & Install New 2 x AC (1.0HP & 1.5HP, both inverter)
3) Conceal inverter piping for all AC (wiring done, wiring already been conceal as per developer given)

P/S: ATTENTION!!...as per developer requirements, holes for AC need to be done using CORING method...appreciate if you can quote "Normal Hacking" and "CORING" in your quotation..

my old house at Setapak is landed...new house is condo at Melawati..
come come quote me... you may send ur quote to "bobadlin@gmail.com"

OK understand ur problem now.

Brother, need some advice here. Just got a quotation and quote me 7900 for installing conceal piping inverter type
1 no of 2.5HP with 50ft
1 no of 2.0 with 50ft
2 nos of 1.0 with 20ft
2 no of 1.0 with 15ft
1 no of 1.0 with 10ft
Is the quotation reasonable?

what is recommended distance ie 1hp ~10ft .. if 1.5? 2.0?
can anyone share ..

I guess I look like a water fish to the contractor, below is the conversation between him and I:
C: how's your consideration of the offer?
I: I will engage other contractor to do the work for me.
C: why?
I: the price is quite high.
C: I propose that you installs back to back, I can re quote accordingly.
I: no need already.
C: May be we can negotiate the price.
I: no need already la. You cannot compete one.
C: how much is the offer?
I: 4 to 5k like that lor.
C: 4k impossible la, 5k plus may be can do la (WTF, want to cheat 3k at least on the first quote)
I: WA... Two to there k different wor....
C: previously what I quote is Hitachi brand piping, the highest end for the air con piping, may be we can use the middle range piping.
I: no need already la, I decided to install after I get the key.
C: don't decide first, let's compare the price, you give me his quotation then may be I can quote you cheaper leh, but you must let me installs for you la... Some more if do it later the finishing not nice one. (cilaka, can't cheat me this time and think of cheat me next time)
I: ok la, let's see how la... (impossible to let him do the work, big buaya)
C: ok, thanks

So guys, get more information from the forumers here, at least you have the bullets to nego with the contractor.
