Hello guys, I'm from Melaka and currently getting few units of Daikin AC for my new house. Just want to check with everyone's experience about the pricing for the services below.

Installation with 10 ft copper pipe, drain pipe etc is included.

But these are additional ones that I need your helpful experiences with

A) Copper pipe above 10ft will be charged at
1.0hp = RM8 (per feet)
1.5hp = RM9 / ft
2.0hp = RM11 / ft
2.5hp = RM13 / ft

B) To conceal copper pipe, drain pipe, to run indoor to outdoor wiring for AC(if needed)
1.0hp RM280
1.5hp RM290
2.0hp RM320
2.5hp RM380

Really need help on this one asap guys. Thanks!
