1st time installing AC

I am installing system 3 inverter for my HBD 3 room flat (resales). Should I go for 9K + 9K (2 rooms) & 9K, 12K, 18K or 22K for my living room (about 25sqM, 6.2M x 4.1M). Heard from salesman the electricity bill is the same whether installing 9/12/18/22K, is it true?

Appreciated for your advice in advance.

P.S : I am looking for StarMex.

To kennyctf,

Ur living room requires ard 12k btu. 18k will be very safe. 22k is oversized.

The energy bills is different from a 9k compared to a 12k or 18k.

Its ok to upsize 1 level up as it 9k upsize to 12k.
But not 9k to 18k, as the compressor will cut off too fast before the desired comfortable humidity level is achieved.

Need some help here. Just newly install a system 3 at my BTO hdb flat. But the room is not as cold as expected when we just turn on the master room. The cold air can be feel but the room is hard to cool. We have a Aircon last time so we know how cold it is when turn on the aircon. Any advise what the problem is?

Terumo, yes aircon contractor says he will make good if leak is due to aircon. But my concern is whether they will do a proper job and solve issue because I suspect another aircon is having same issue! So I am very worried it is a question of them doing the installation incorrectly and repeating the mistake elsewhere Really hope they fix it properly now.

Thanks again for your help.
Hi Terumo,
Would like to get your comments on whether there is any particular brand/type and thickness of insulation for the concealed air con pipe?
There was so much water when the floor in the slab when it was hacked and up to now, cannot really determine where it came from. There were two connectors (at the bend plus another one just after it to extend the pipe). Still doing tests to determine source!! Thks

To sunshineflower,

Usually i see contractors using Armaflex 1/4 thickness insulation.
This should be sufficient.

Just realise in Sg you guys why needed piping upgrade from G23 to G22?

These is thick enough for G23, in M'sia I am not sure what grade of the copper pipe size, just enough to install non inveter only.

See at the photo really thick on G23.

With good workmanship any grade also can be works well

How is the service of GC?

Their price is slightly higher for StarMex Sys 3.

Worth the price?

Price on the higher side

Was quoted $3,199 for Starmex Sys 3, 2 x 9K & 1 x 18K, bracket $150 & $180 upgrade from Armaflex 3/8" to 1/2" & copper pipe from gauge 23 to gauge 22.

But is GC service worth the higher price? Just want to have a peace of mind for the next 3~5 years.

Any comment?

Thanks in advance.
