60ft = 20m, it is at the limit of of performance for fully inverter unit. The option for non-inverter unit is totally out of consideration due to distance limitation.

Some Strata, they limit the location to place the outdoor unit but they will specify what type of AC to use ( inverter or non-inverter).

This is a common issue with the newly built unit, developer want to conceal the piping in the slab. But once the piping leaks, it is almost impossible to detect / repair. Ended up, the AC contractor usually will suggest to by-pass the old pipe & run the new pipes. Just like the old plumbing pipe in old house, if you ask the plumber go to detect & repair, the plumber will ask the owner to by-pass with the new piping.

last time had the same problem, but we did detect the leak.
instead, reinstall the ac back to back to balcony and put condenser there with short piping requirement.

Modern R32 system no problem. Example cheapest Daikin 1hp can go 25m~82ft. I've even done 30m installs (no elevation changes tho) with no issue.

Edit: Copper Pipe for 1hp-1.15hp would be RM12 for 2 feet. What cost a lot is the labor. (Open ceiling, run new pipes, close ceiling, seal wall, paint).

IC, if the compressor location is fixed you may have no choice but to repair the leaking.

Perhaps you can arrange for someone to inject pressurized water into the copper pipe to locate the leak, and then cut and replace the damaged section with a new piece.

but all this need try and error. or else change new copper hose.

hope you get best solution without spen big amount.

yeah I have a hunch on that one.

that's why I am delaying to do so

friend...if I can do that, would have done it long ago lah.

But I live in Condo, and the management don't allow this

bypass very ugly la

will make my house look like a space ship with black hose running through the ceiling.

1. is your outdoor unit really that far away? who the fuk installed an outdoor unit through concrete 40-50' away from the indoor unit?
2. how did they route the drainage? if the drainage anywhere near as long as the copper piping, I would be surprised if it isnt leaking somewhere and causing damage or mold to your house.

as others have noted. just need to repair the part that is leaking. by right, you shouldnt need to replace the whole length of pipe.

mine was condo. i asked management, why many can put in balcony. they say common problem and allow.

yes it is at the other side of my condo, near the wet kitchen where they house the split unit fans which are hidden by a wall of decorative metal cladding.

you be surprised how fuked up developers are these days. All aesthetics, no proper plan for these eventualities.

The copper piping goes from my master bedroom through 2 other rooms then L-share bend and through the kitchen then through to the wet kitchen and to the fans.

Some of the piping goes through the plaster boards that have a small door open to view but 50% of it goes through the concrete ceiling....

it some ways the contractor say is logical

You put a proper PVC casing to conceal the insulated piping, run it at the edge of the walls. That would be the cheapest & reliable option.

If you want to conceal by hacking, it would be worse.

Ugly = temporary. Use this to motivate yourself that you are going to move out to bigger house in near future.

It was not the problem to be faced by me. It was other people's problem, actually.

I just got to know the issue & try to understand the scenario from the people who face the issue. At least I know how to deal with this issue for another application.

Anyway, thanks for your wishes.

Is any part of the copper buried in concrete?

Previously my aircond copper pipe leak during service, they just welding it, until now perfect

If your pipings are concealed suggest to change whole copper piping
How old is your house?

Reason being there might be multiple leaking point
let's say if you hack your wall and found one leaking point
then you weld back
after few weeks if not cold then you need find other leaking spot
hacking + weld + conceal again
double work.. labor alone will be hefty

Not suggest to do half baked work
the technician also will tell you they will not guarantee.. after repair done
because if the pipe is old and started leaking, potentially other section have same issues or will have same issue soon (almost time)

This also depends on quality and thickness of the copper pipe used by your contractor

Even if you hack the whole pipe to inspect and weld back muitlple leaking spots
don't think the repair will be as good as brand new copper pipe

Just need to ensure your technician using good copper pipe
one time repair and you're good

Don't get yourself trouble
if change.. must be brand new pipe

Got hacking, drilling and conceal?
from wht I know.. the installation fees not include those above

If all included, maybe TS can double confirm again before hiring them
because it's cheaper than change/repair old piping

is brand new

no wall hack. The job scope are replace old in & outdoor unit and piping.

thats crazy man. the developer might have been better off putting up more decorative metalwork on the other side.
