Air conditioning - Any recommendations please?? - Part 2

[fissionstar]

Any1 can suggest me good and reliable retailer, pro shop or others ac company shop ?

I'm going to purchase new ac and most likely choosing Dai Kin iEco smile series.

I am taking into consideration to get system 3 ac for my old 4 room hdb flat for all bedrooms 12k btu each.

For the dai kin ac specs I will probably pick,

Indoor units
CTKM35VMG - 3 x 12000 btu

Outdoor unit
MKM85VVMG - Max capacity 36200 btu

I should be able to switch on all 3 acs since the outdoor unit btu are sufficient. As for btu calculation for all room I need about 10.5 k btu each.

9k btu for each room is too little and require more time to cool the room although I have an old system 1 ME ac in master room that still works fine.

IMO, 12k btu bedroom is good enough and cooling the room much faster.

What are you thoughts about this?

Thank you all. I accept all fair criticisms, as i admit i did not read all 330 pages of discussions here, but i started following recent discussions!

It's an old 20yo condo. Have gotten 2 AC installers to do site visit for quotation and i'm following their advice for required BTU per area. So to clarify, i'm seeking advice on the right combination to use

Am leaning towards this -
ME Sys3 (3H28): Living 24K + MBR 13K
ME Sys2 (2H20): Bedrm1 10K + Bedrm2 10K

1 of the AC guy suggests: (abit shock, i thought Sys3 can't support all 3 rooms at same time)
ME Sys3 (3H28): MBR 13K + Bedrm1 10K + Bedrm2 10K
ME Sys1 (R32): Living 24K

option 2 much efficiency
System 3 basically don’t have 24k cooper pipe size. Have to use converter from 9.5 to 12.7 Dia.
If you have refer to ME brochure, system 3 capacity can go up to around 18k ++ BTU maximum only.

Prefer system 3 (10+10+13) and system 1 (24) that is prefect combination

Maybe this had been discussed before, or I missed it.

My friend just got her 3rm resale at Marsiling and installed Starmex. The pipings are run at the bottom instead of at the top (beam or ceiling).

what could the reasons to do so?

Depends on layout, I ran mine at the bottom on the nearest room to the condenser.

 

[petetherock]

Hmm that Daikin compressor does 26500
I don’t see a higher number
Trying to make it fit when it’s underpowered?

like the other posted said, depends on layout.
the main benefit is that the drain pipes make a drop from the FCU immediately instead of running horizontal. this setup is almost clog proof. the water pressure will push any clogs in the horizontal portion.

can switch on all 3 is one thing, cold or not is another, how long to cool all 3 is an art.

Say you switch on 2 first, it would need about 7.0kW or 24K BTU. After 30mins or so, both rooms cooled and cooling needed can reduce to say 50-60% so can switch on the 3rd.

another thing is west sun and hot room. My current place the bedroom I am in is extra hot (no west sun).

ya, west sun really taxes the aircon. need to consciously draw curtains and put solar film to minimize the rate of heat transfer.

 

[petetherock]

The cost of those solar films might pay for a bigger compressor and then some... or a decade's worth of PUB bills

add bigger condenser unit and Solar film

Installer told me rooms with air conditioner can't use fragrance or oil diffuser, will cause pipes to choke. Is it true?

Hi all Aircon experts,

Just collected keys for my resale condo (8 years old) which was fitted with Daikin Aircon:
1. System 1 12k for master bedroom
2. System 1 9k for living room
3. System 3 9kx3 for dining, bedroom 2 and 3

I’m planning to hack all the existing false ceiling and considering to replace the Aircon to ME STARMEX which I had good experience with for the past 10 years.

I was told that typically the Aircon retailers will be charging more on the installation for aircon units for condo, is that true? I dropped by Gain City yesterday and was told they would need to charge additional 500 for each FCU which I don’t understand why since I would be redoing the entire false ceiling. Would appreciate if anyone can advise me the reason for the higher charges applicable for condo units..

Enclosed is the original aircon layout plan and I am thinking to replace with the below configuration. May I see for your kind advice if it would be a good config?
1. System 2 - 12k for master bedroom + 12k for living room
2. System 3 - 9k x3 for dining, bedroom 2 and bedroom 3



thank you all!

 

[petetherock]

I can't see your diagrams or the changes
But expect more costs for a condo, yes, you can nego with the vendor if you recycle the pipes
If you entertain a lot and your dining is big 12k might be better especially since it's open. Likewise for your bedroom 3, which looks bigger than bedroom 2.

Good luck and ask the vendor to give you an assessment of the power needed.

Thank you! Actually is it a good idea of re-using the pipes? I was told if re-use the existing pipes I need to use back the exact same config as the original setup which is quite weird (3 CU: System 1 + System 1 + System 3).

Btw any reputable and trustable vendors to recommend? Thank you~

 

[petetherock]

Can reuse, but can re-route some sections if needed or bite the bullet and re-do, no right or wrong..
Check how the pipes run and the vendor can help

The reason should be because we have money to pay..?.. think they want to make more profit through the installation..

Did new aircon installation on my resale condo. Was quoted 3k extra to clear the pipes, install etc.

Fortunately my wife has a previous aircon installer contact. Had to destroy the false ceiling to make many entry points to remove and change all the pipes etc. paid a fraction of that 3k quoted extra ..

What should be the recommended configuration for a 4 room flat, 1 master, 2 common (1 of them is study), and living room + dry kitchen (separated by glass between dry and wet kitchen).

Does a system 4 - 24/12/9/9 work? biggest for living room which will operate as a standalone or 1 master + 1 common, rarely will turn on all 3 bedrooms unless we have guests.

Or does a system 5 12/12/9/9/9 work better? split living and dining / dry kitchen into 2 separate 9/9 or 12/9 units?

I don't have enough budget for 2 systems at the moment (system 2 and system 3) and will almost be using all units mutually exclusive. Will not power whole unit but only the communal spaces or the bedrooms (study room at best a sofa bed but will only use in the day for office work)

i would use as many sys1 as possible. if the aircon ledge can hold. if you going to live there long enough. it is always better to replace each sys1 as it spoils.

Hi, which store to buy aircon the most reliable and cheapest?

 

[Imsai37]

Planning to replace my ageing (22 Years) Sharp Sys 3 Aircon with ME MXY-4H33VG Sys 4 (9x2 + 12 + 18) and was offered by Audio House @ $4942.00 including standard installation. With using climate voucher, it will be $4642.00. Plus additional 1320 eCashback which can be used for future purchases $20 for every $100.

Same system was offered @ $4196 (using Climate voucher) at HN. Is this good price to consider HN over AH.
Anything to take care in terms of installation as HN likely to use 3rd pary installer.
Please advise.
Edit: Audio House NOT GC. Apologies.
