inverter and non-inverter piping is different?

i did one 2hp (non-inverter) cost rm450 include well conseal job done by my contractor.

total abt 15ft in my double terrace house, copper pipe start from living hall's wall till go up above plaster ceiling, then throught a drilled hole to above car porch ceiling and roof tile.

include replace 1 pc of car porch ceiling w/o paint + pvc sealing for the roof tile.

while the conseal water pipe go down along the living wall -> through a drilled hole of the front wall -> fencing wall -> drain.

i think it is worth because a lot things need to do.

I'm done me with RM1800 for 6 a/c
If not mistake 4 unit within 15 feet, another 2 should around 20 feets

Added on November 3, 2011, 10:22 pmjuz got a quote:
1hp copper pipe wiring - rm12 per ft
1.5hp copper pipe wiring - rm18 per ft
hacking and conceal water pipe - rm200 per point , no plastering
not include installation charges yet..

means the quote is reasonable?

This was the quote i got from my air-cond guy.

1. Living Room area - Type: 2hp / Standard : RM1,150.00
2. Dining Hall area - Type: 1.5hp / Standard : RM800.00
3. Kitchen area - Type: 1.0hp / Standard : RM550.00
4. Ground Floor guest room - Type: 1.0hp / Standard : RM450.00
5. Master Bedroom - Type: 1.5hp / Inverter : RM750
6. First Floor guest rooms - Type 1.0hp / Inverter : RM450 x 2 rooms = RM900.00
All the work is for concealed water and copper pipes with installation placement of the compressors at the rear rooftop of the house. I don't have the exact length but i know its very far especially from living room to back of the house.
For supply and installation of air-cond units, the price is as follows.

Panasonic 1.0hp / Standard : RM980.00
Panasonic 1.5hp / Standard : RM1,300.00
Panasonic 2.0hp / Standard : RM2,000.00

Panasonic 1.5hp / Inverter : RM1,650.00
Panasonic 1.0hp / Inverter : RM1,350.00

Most of my friends have used this guys to install their air-cond units over the years and he's been quite reliable. Not too sure how the quality of his plastering work is as no one has used him to plaster their walls completely before. He mentioned that the price for the supply and installation of the air-cond units changes depending on the current price he orders the units at that point in time.

Hope that helps.

Better not, in case of condensation and leaks. If that happens your wardrobe is as good as gone from water damage.

I used to go to SS2 Legend quite regularly in the past but i feel that their service and discounts nowadays is not as good as before they got so big.

For centralized water heater was quoted RM60 less than Legend's quote from another supplier for the same product.

May i know what happens if you find that there is moisture / water stain on the wall where the conseal piping is located?
Is this normal?

or any where to conseal the leakage / moisture without hacking?

Thanks

No worry. This thing can be solve easily.

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?? 

Decorate it with some leaf and flower. 

Hi all

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

can i use inverter piping for non inverter air cond?
