aircon repair is never cheap. anything down will cost hundreds of dollar. the site visit alone for troubleshoot without any repair will cost around $100 per visit.

daikin is the best buy now with the extra 2yrs warranty on parts and if add in the 1st year warranty total is 3yrs.
mitshibishi was very popular largely due to the advertising and marketing. they got the most advertisement out of all brands.
if pricing aside, i will pick daikin over mitshibishi follow by panasonic or toshiba.
if go google or ask around all brands also got good and bad review. same brand some people using 8~10yrs or more without problem, some after the 1st warranty start to give problem and need to cough out hundred of dollar for repair so the best assurances is still the warranty. any issue we still can go back to manufacturer for repair work and that will save the cost alot.
redcon air troubleshooting will cost only $50....

To doraemon123,

You should get the 5 ticks as you will save back on the energy savings.

For master room, if budget permits, you should upgrade to the 12k btu to make it more efficient.
As 12k btu will cool down the room faster.

After i tell him hdb with40A main switch limit is not under 8.5A aircon limit guideline, he told me he will double check with senior tech.
I will wait and see.
At least he make effort to double check instead of ******** with me.

I will make sure they switch my compressor ampere to full load. Otherwise, no point getting VA38.
Its as good as buying sport car but set fuel limit to very low level.

Can I check with you all, in my new 5 room bro, I got a 20 Amp DP isolator. If I want to use a system 1 and system 4, do I need to run another power point? Or can just use the same 20 Amp DP for both condensing unit? Thanks.

The model I'm going to use is Starmex 9000 Btu system 1 (4 ticks) and Starmex 28000 Btu system 4 (5 ticks)

Anyone using 2 systems kindly share the information... Thanks.
Since i got this answer already. I'm thinking its better to share here (disclaimer.this is for sharing only, no guarantee its 100% correct. only correct up to my knowledge) :

1. 20 AMP DP Pole can support for 2 condensing units as long as it never exceed 20 Amp according to my HDB estate officer. For my case starmex 9000btu running current is 3.30Amp and starmex 28000btu running current is 2.6 - 12.65Amp. Meaning max is 15.95 Amp. No issue from HDB point of view.

2. Called Mitsubishi, and was told even though its below 20A, it is not recommended to install on 1 DP as it might cause problem such as PCB burn or fire safety issue. was suggested to pull a power from Master Bedroom heater point instead because heater point is 15Amp. this point is for the smaller size condensing unit.

3. those who think of using system 2+2 or 2+3 definitely need extra power point/isolator due to high current usage on each system.

Thanks for the advice.

If I were to choose Daikin, any recommended models? I saw some models with 5 ticks but salesman kept mentioning that the power is not sufficient for my layout.


To doraemon123,

For master room, if budget permits, you should upgrade to the 12k btu to make it more efficient.
As 12k btu will cool down the room faster.
XC

For new model, we will not know the common issues will surface later on. But surely the spare parts will be expensive.

I do feel Mit Elec 2 ticks model price quite exp against those having 3 ticks for the same system 3. Maybe due to lot of TV advertisement fees need to pay daily.

you can see the chart below to compare:

“Many people buy an air conditioner that is too large, thinking it will provide better cooling. However, an oversized air conditioner is actually less effective — and wastes energy at the same time,” explains the very helpful Energy Star website. “Air conditioners remove both heat and humidity from the air. If the unit is too large, it will cool the room quickly, but only remove some of the humidity. This leaves the room with a damp, clammy feeling. A properly sized unit will remove humidity effectively as it cools.”

did some reading about the BTU
for hdn bedroom or even master bedroom a 9000btu fcu is more than enough. for living room a 12000btu(i thinking even a 9000btu also fine) will do but there other factors like number of people, near to kitchen, tv, facing sun direction, all these will contribute to heat and will need thr extra btu.
best go for proper balance sized fcu.

So far based on what I read so far, seems that higher the ticks, lower the performance (in terms of cooling power).

If that's the case, I rather go for lower ticks to get a cooler room.

Exclusive 3 months warranty extension will be given to selected airconditioner models purchased at Daikin Retail Proshop. New products will be first launched here too.

http://www.daikin.com.sg/index.php/c...proshopdealers
GA dont sell Daikin rite?

i prefer to go for daikin pro as they are listed on daikin website and if install by Pro there will be extra 3months warranty added in the 3yrs warranty. Pro should have better workmanship and using better material.
maybe Pro are more expensive comparing to those small firm but i check Gxxx Cxxx for Mitsubishi system same configuration about same price?
i rather spend abit more, in long run it is still worth as lesser headaches for problem due to the workmanship and material.

for installation spec i will go for
G22 copper pipe LHCT brand
at least 3/8 armaflex class 0
16mm drainage pipe
Keystone 4c40 control wire to fcu(if will to spend can consider upgrade to 3c70 wire)
for main power point to compressor the stand wire is 3c70

some firms maybe offering lower cheaper price but if you look the package they are giving lower grade material.
but at the end still depending on budget and how deep the pocket and willing to spend.
