My sis went to check out the Panasonic sys 3.

They offer to upgrade the copper piping and insulation for another $180 - is that really necessary?

An experts can give advice?

Then we currently have a steel bracket for the existing Daikin condenser, so can retain it for the Panasonic one?

On a budget, so must save whatever can save

The sales guy also tried to push for Fujitsu - he say it's DC inverter so can save even more energy than non-DC ones e.g. Mitsubishi Starmex energy thingey is 1.4 vs Fujitsu's 0.7. That like quite a lot!

What do you guys think?

quite standard pricing. Gain City also this price coz i'm looking at this configuration too. The lowest I can find is ard 4.3k from Tim in Renotalk butI cant seems to find reviews on him anywhere even though he is not a newbie.

To plasticpistola,

Upgrade of materials will depends on ur piping routing & usage rate.
Panasonic now having promo, so prices should be quite attractive...
I will prefer Pana over Fujitsu.

Charges to change pipes

Anyone know what is the estimated charges to change the piping in a condo?? My existing piping is close to 10 years and i did think of changing the pipes together with changing my existing system 3. The blower in my master bedroom is always not cold.

I got 2 quotes for the pipes. 1 quote me for ~$450 per room (x3) while the other quote me flat pricing of $1500.

Is the charges about right??

Need some advice.

Gonna get MSY-GJ10VA (Mitsubishi inverter)

I want to have it installed optimally.

What "better parts" go with it?

So I've been informed to get Inaba Denko paircoil (6.35*0.81 + 9.52*0.81). Are there any other parts that require 'special order' that regular aircon installers do not often include?

Also, to install this pair coil, there some special tools needed? Or will any air con installer know what to do?

Also is 0.71 thickness sufficient for R410A?

To Teach_Me,

For condo, usually have to get them to come down to see for a accurate quote.

To biatche,
I think normal g23/22 piping with Armaflex insulation will be good enough.

To initial_2004,
Will u be using all 4 units together most of the time?
If not a 27k btu compressor will be good enough, which Panasonic have for 27k btu.

Inverter System 4 - 9k BTU x 2 + 12k BTU x 1+ 18k BTU x 1

Hi all,

Looking at Inverter System 4 and shortlisted the following options:

1) MHI SCM80 (32k) with SRK25 (9k) x 2 + SRK35 (12k) x 1 + SRK50 (18k) x 1 ($39xx)
2) Daikin 4MKS80 (34k) with FTKS25 (9k) x 2 + FTKS35 (12k) x 1 + FTKS50 (18k) x 1 ($4,6xx)
3) ME 4A28VA (28k) with GE10VA (9k) x 2 + GE13VA (12k) x 1 + GE18VA (18k) x 1 ($3,9xx)

Includes 1/2" armaflex, G23 copper, 16mm water pipe, keystone/tai sin cabling, and standard HDB installation (up to 15 metres).

Two questions to seek your recommendations:
1) Are the pricing reasonable?
2) Which of the brand options would be better (and why) in terms of:
(a) reliability/durability
(b) ease of maintenance/self-clean
(c) service and support

To justonenonly,
MHI should be cheaper then Mit Electric.
Among the 3, i will choose Mit Electric as its the most value for money.

Is workmanship an issue if reusing piping?

Hi All,

Due to conceal piping, changing them would be a hassel, as such I intend to use back my current piping and just replace my system 3.

I got three quotations for the system 3 which i intended to have but there seems to be a huge price difference

1) Gain City = $2XXX
2) Contractor A = Gain City + $150
3) Contractor B = Gain City - $350

Contractor A is highly recommended for his workmanship, but it seems that he is charging a lot. Was thinking if i should engage him or get the one that offers the lowest price as i am not going to replace my piping.

Thanks in advance for any thoughts and suggestions.
