Why can't just hack the vertical wall and go through by the vertical wall ? 1 hole instead of 2 hole.

You can just silicon seal the hole. But there is 1 problem. After some yrs, the insulation will start to crack due to expose to sun. (if that area is outside) And the leaking will start.

Possible to leak.

If silicone you referring as the silicone use for the glass, i doubt it will work. You need waterproofing from sika, or PYE.

The ground floor ceiling height is similar as my car porch roof. So they cant go through vertical wall.
silicon seal and plater with water proof? I haven go and check bcoz just done only.

The black insulation that cover the pipe is a foam. It is soft and cannot stand to UV expose for many yrs. It will brittle and start to crack. The rain water is staying on the ground and not flowing fast away. If the pipe from the vertical wall, than the rain not easily sip in.

You need to do additional thing to secure the water from leak in. Anyway the leak won't be that fast. Silicon + water proof paint can last longer. Very much depend on your skill.

Actually for piping this way, there is a proper way to open the hole .

Silicon already cannot paint. Silicon and paint won't mix.

Can la. Got some silicon that can paint. Brand bostead if not mistaken. Than paint it with PYE flexi seal. The whole insulation need to be paint also.

If the black insulation is also in the concrete slab, good luck. That insulator over time will shrink and deform and will create opening for water to slip in.

Definitely after some yrs.

No need to wait long, max i give 2 years see the black insulator shrink. I can see mine already shrink bit. Especially the one exposed to rain and sun.

mine took less than a year. cracked and changed already. guess it was cause it was under direct sunlight everyday

hi i am quoted with following price for conceal inverter piping, reasonable?

1. install 1hp inverter aircon @RM180
2. install 1.5hp inverter aircon @RM200
3. install 2.5hp inverter aircon @RM280
4. conceal copper pipe 1hp @RM480
5. conceal copper pipe 1.5hp@ RM530
6. conceal copper pipe 2.5hp@ RM750

all less than 10 ft..

now a day non-inverter aircon also can use inverter piping right?

yup, just not vice versa.
install inverter now, in case in future might change it to inverter type.

how to know the piping is ready for inverter aircon?...currently installed non-inverter aircon

thanks..

inverter aircond pipe is more thicker since using different gas type.
previously read it with pic somemore, but too lazy too google now.

I got quoted recently by my wetwork contractor:

Air-cond Installation price:
1.0HP - RM300.00
1.5HP - RM350.00
2.0HP - RM450.00
(If aircond not installed by him, water exit point RM120/job)

Copper Pipe (concealed) - per ft
1.0HP - RM18.00
1.5HP - RM22.00
2.0HP - RM25.00

Electrical Wiring (concealed) - 15A
RM220 per job

So for 1.5HP installation with "standard distance":
RM350 + RM 220 (22*10ft) + RM220(15A wiring) = RM790

Is this reasonable? This is from my main con who is also doing kitchen extension for me, total lump sum work about RM 50-60k.

Anyone know where to get this aircond pipe cover and compressor supporter?

[attachmentid=4600373][attachmentid=4600374]

A bit expensive...I was quoted RM 280 for 1 hp and additional ft conceal piping of RM 15.

hi guys sorry for posting on old thread,

if i wan to do conceal of copper piping in the plaster ceiling, shld i install the aircon first or install the plaster ceiling first?

Should do all the piping first than do the plaster ceiling. Lastly install the aircond. Anyway why want to put the piping in plaster ceiling ? Is better to conceal inside the wall
