Question

hi all,

Just wish to update everyone here on my air con installation by Gain City on Monday and Tuesday. It ended today.

Comments:

a) They did bring along G22 copper pipe, Armaflo 3/4" insulator as stated. Bro, these insulators are BIG.

b) Mine is sys 3 and they used 3 coils of new copper pipes for my system. They do not want to join copper pipe as this will leak (weak point) if not don't properly.
Some installers may join copper pipes to save cost to re-use left-over pipes from previous installation.

c) This team of installer (2 persons) is very helpful, thoughtful and willing to listen. Mine needs to cut false ceiing to lay pipes, and they are very accommdating to whatever you suggested, cut here or there so not to leave obvious marks etc. No 'show face'. Most importantly, they don't rush for time, bend the copper pipe properly and systematically and as the result why they took 2 days to complete the job

1st day to install pipes and air-cons so that I can test-run overnight to monitor for leak or sweating. The next day will be for sealing up the false ceiling and painting. Normally, 1 day is enough without false ceiling cutting.

I tried to ask for they names but they rather be addressed as team no. 2139. This team is highly recommended.

d) So far, MHI is good, very cold even on hot afternoon today. 26000BTU is strong enough even when I run 3 rooms together.

e) Fan-coils are indeed very quiet. I like the feature whereby beside tilting up-down, it also able to move left-right for the wind direction, so everyone in the room can feel the 'cool wind'.

f) It also have the auto-dry feature whereby after turn-off the air-con (compressor OFF), the fan is still running inside for 2hr, drying the coil to prevent moulds.

Thanks.

Hi All,

I just bought a System 4 from Gain City and it was installed a week ago.

The compressor leaks water as shown below and the servicemen who came from Toshiba says that it is natural / common but I don't think so because I've never seen compressor condensing / leaking water before in my whole life except for single unit window mounted air-con or air-con inside our unit.

Can somebody share with me the situation and what should I do? Please reply to patrickong@gmail.com if you have the exact answer so that I could quote and complain to Toshiba again tomorrow.

Mine also toshiba and same thing there is water leakage also at the area same as yours.

G23 enough for HDB exposed piping. G22 is for commerical/private concealed piping. G22 overkill for exposed piping.

After a week reading feedbacks from several forums, I decided to pick Toshiba over Mitsubishi Electric for its "made in Japan" label and the drying mode function. Electricity is not a big concern since I on AC only at night 6~8hrs.
But, need more advise frm AC gurus here to choose the right setups.

setup 1: RAS-3M20SACV (outdoor, 24K Cooling cap), RAS-M13SKCV (indoor) x2
setup 2: RAS-3M20SACV (outdoor, 24K Cooling cap), RAS-M13SKCV (indoor), RAS-M10SKCV (indoor)

PS: MBR is of typical 4 room flat MBR size. Total AC on time for 2nd room (guest room) in the past 3yrs <50hrs.

Thanks!

What are my options?

I moved into this 5 year old 4 room flat circa november 2009. I installed MXY-3A28VA / MSXY-GA10VA x 3 in all the rooms and now I'm addicted to it. This a/c is great, i set to 28C and the room is cool enough for me.

Being addicted means that I need a/c in my living room as well... What are my options for installing a/c in the living room? HDB can have 2 compressors? I guess I also need to install a door to seal off my kitchen. So roughly how much cash do I need to prepare? I don't need to cool a lot, 27.5C at 50% humidity is enough.

Thanks in advance!

Hi, need some advice here after reading through many of the posts here.

I want to change the aircon in the 3 bedrooms as they are already 9 years old and start having problems. Currently using Daikin 4MK75FVEN (inverter with R22). The piping are running in the false ceiling. Bedroom sizes about 120, 130 and 150 sqft.

Thinking of changing to non-inverter aircon like Daikin MA56EV1 but worry not cold enough. The other alternative is to go for inverter aircon but cost about $1k more. Usually we will turn on aircon in 2 bedrooms throughout the night. Any advice?

Should I change the current piping? (I know if I change to R410a gas, then must change piping). If don't change, worry got problem later. If change, it will be messy and not sure if the shop can patch up nicely after installation. Anyone has experience on this?

Do the shop normally charge for removing existing aircon?

Thanks.

Just to ask some opinion as looking to install air condition. My masterroom is around 30sm and common room is around 15sm.

From the website calculator, it seems I need around 12k BTU for Masteroom and around 8k BTU for common room.Initital I am eyeing for mitsubishi starmex but seems it is running out of stock now. GC guy introduce me toshiba

However I am having doubt on the combination:

1) RAS-4M26SACV( system 4 outdoor unit with 34k BTU), RAS-M10SKCV(9000 BTU) X2, RAS-M16SKCVX1

2) RAS-3M20SACV( system 3 outdoor unit with 24k BTU), RAS-M10SKCV(9000 BTU) X2, RAS-M16SKCVX1.

First doubt : Can RAS-3M20SACV support the second combination without any problem if I always on 3 aircond for night?

Second doubt :Is RAS-M16SKCVX1 enough for 30sm room or I need RAS-M22SKCVX1 for masterroom ?Actually the GC guy recommend me RAS-M22SKCVX1 before I get the web calculator.

Appreciate help from all expert here. Thanks
