The wall is face outside, right?
If the hole no cover up raining water will no go inside?
Bird/insert will not go inside? Even the air con block the hole but still got small gap there

Outside, inside also the same.
Insect unlikely to enter since we already blocked it with paper.
As for rain water also unlikely since it is covered by roof, chances of getting rain water are quite low.

Simple and flexible
Maybe future got change get landed house can do this way

Nothing to do with landed or not landed, you just need to plan properly.

Condo management not allow simple hack and air con compressor got special place to put de.
So cannot just put next wall with indoor air con.

hi,

my house has this piping for aircon,

1. can we tell if this is for inverter?
2. Seems like there is a pipe for water outlet is missing/not available?

You can use plaster ceiling sides to cover the piping.

Looks like normal non inverter

i see, thank you.

then i would have to take a painful route to remove the pipe and replace with inverter one.

Yup, but this time put a PVC pipe to it, seal it back and paint.
From next service onward, no more hacking works.

Cover with plaster ceiling still need to hack the wall for go back down side because a lot of beam....cannot just straight go thought beam.
Not good for gas pipe to go up and down too much so i just do hack conseal in wall.


Just see the pic can know the pipe is inverter or not......

Nope, the covered part should be the non removal part. Usually the connection point is the main concern on any air cond installation.

Hi, I was quoted conceal paiping as below,

3 x 1.0 hp, 1 x 1.5 (R410) = 1k
1 x 2.0 hp = 300

The exact length not sure but is a lumpsum. Base on the site visit, the min conceal length is at least 6 ft per unit.

Aircon --> Daikin, installer Daikin authorized distributor

Install a 1.5HP air cond only need rm150-200, including piping/wiring for the first 10ft.
2HP will be rm200-250, again for the first 10ft.
Above are including brackets.

normally if exceeded 10ft, how much is the price perfeet include conceal? for 2.0 and 1.5, 1.0.
Actually my price quoted is for conceal and additional length. But never stated how long is the length.
Again, if within 10ft, how much normally will charge for 1.0 HP and 1.5 HP?
I read previous post, does the conceal price is purely for hacking work? Because the aircon I purchase is included standard 10ft installation. If conceal how much will be add in? Exp my 2.0, the shop quoted rm300. So is 300 for purely hacking only.

Anyone have approach contractor or aircon installer for the copper to be conseal into wall before aircon installation?
I have 3 bedroom + 1 Living room. I would like to know what is the price per feet for below:
1 HP aircond (non-inverter type) (Guestroom)
1.5 HP aircond with inverter type (master room)
2 HP for living room (Non-inverter type)

I find majority of lowyatian mention that non-inverter will use different copper right?

Please comment on my house conceal piping.



I'm so sad that the con broke my room/house beam. Is that serious, or just crack only?

This is in the master bedroom and second floor. My house is DS intermediate.

If unsure, ask wet work contractor and check. You may have to knock out the crack open area only can tell. Look to me is just the plastering layer. I could be wrong, only can tell after remove the crack area. If the other side no problem very likely just the plastering.

Hi , just done my conceal piping. But concern on the water leaking. They make hole on my concrete roof and lay the piping then cement it back. But not sure what cement they use but they said no worry no leaking.
For the piping out from root top, can we use the silocon to seal the gap then apply the water proof on it?


Attached thumbnail(s)

The crack layer is quite thick. If this beam is horizontal to your house, better check properly.

Hmmm think you should get some advice from a few contractors see what they say. So you can compare responses. Just want to be careful when you seal stuff up. A lot of times it's just masking the problem on the surface. I once had a leaky pipe concealed running from my attic that I didn't know about - it was a problem for A FEW YEARS no kidding. Until I got a guy to really do a thorough check only I managed to spot and fix it. Same thing - the earlier contractor just sealed the leaking area but didn't trace where the real problem was
