I'm planning to get a Sharp Plasmacluster System 3 inverter for $2399 incl. gst.
Does anyone using this aircon? Is it good?
The SM offer me the blower 12k, 9k & 7k which roughly correspond to my room size.
Normally it is 7k for all 3 blower.

Thanks!

Hi,

I am also searching for sys 3 inverter and doing homework on various brands and model. May I know what is the BTU rating for your condenser unit ? 26000BTU or 28000BTU ?

Please advice.

hunting for air-con as well....system 3

look like in term of BTU for system 3 inverter, Mit has the highest 29000+BTU. Daikin, Panasonic, Toshiba around 25000+BTU condenser unit for sub 3k range with 9+9+12 setup.

Sale guy said that it is OK to have gas pipe bigger than specification, but not smaller. Is this true ?

Anyone can comments ?

hi chunlianghere,

why little people use Sharp? i think they been around a long time.
I do notice there's no discussion on Sharp in this forum so i guess it's not that popular.
all i want fm my aircon is cool enough liao & not to buy overspec for our rooms.
In fact I've bought over the years Toshiba/Daikin/Panasonic/LG inverter.
I use to go for the highest spec eg system 4 compressor but 3 blowers only.
But we only switch on aircon only on the hottest/hazy months of the year so sayang lor.
we stay at high floor so it is cold during the rainy seasons.
also my kids are sensitive to dust hence the proven plasma feature, too cold then will have running nose.
so much for my ranting... wonder anyone in the same situation as me?

Generally how long does an aircon last?

I have bought a resale unit with 9year old aircon (same as age of flat).
It has 5 aircon outlets, 3 for each bedroom and 2 for living room. Not sure about BTU. The seller said that its working fine with no leaks. They service it every two years.

Now I am thinking whether I should change the aircon with rest of reno and avoid hassle in future. Or I should continue using till it fails on its own...

What do you suggest?
Do the aircon companies give any discount for "trade in" of existing working aircon.

actually no need system 4.. as long as the total fcu btu is same as compressor btu, it is enough liao.

IMO, 9000btu for bedroom is jus nice.. is u say 9000btu is abit overspec, than i scare tat later it will take a longer time to cool the room if initial on.

so well, its up to u to decide. :)

Hi,
Agreed with Chun Liang, better changed together with reno...Dont like me, regret didnt do it during reno, now even wants to install air-con for the living room also have big issue. I have to cut holes here and there to lay piping.

Now, my air con for my 3 rooms have Gone (using for 9 years leow so problem comes), and planning to change a new set. Headache on the piping because to change piping, have to cut holes to lay pipe, very troublesome.

In summary, change NEW set together with piping....I kindest advice.

I have seek advice from bros here whether to change piping or not, and my decision is now clear.......CHANGED.

Thanks

Yes..the living room quite big. 6.25m x 6m. Last time I checked even 2 were hardly cooling the room. I still havent got possession of house, so cant check fully. Aircon is Fuji brand. Ideally how much BTU needed for this size living room?

Thanks for the advice. I am also seriously considering changing everything now. Better do it during reno. Dont have to go through hassle again..though it will be an extra cost right now ! Also the old aircon become yellow !! looks dirty. Hopefully can get some trade-in discount for old aircon..

How much extra does it cost to change piping?

18,000BTU is normally enough for living room.

Did some homework on different makes for your reference on sys 3 inverter:

a) Panasonic sys 3 inverter r410a
CU-3S27JKZ (25600BTU) compressor
CS-S9JKZW X2 (9000btu FAN UNIT)
CS-S12JKZW X1 (12000BTU FAN UNIT)
Cost $3220

b) Daikin sys 3 inverter R22
3MKD75DVM X1 (25590 BTU) compressor
FTKD25DVM X2 (8500 BTU FAN UNIT)
FTKD35DVM X1 (12000 BTU FAN UNIT)
Cost $3025

c) MIT sys 3 inverter r410a
MXY-3A28VA (30366 btu) compressor
MSXY-GA10VA X2 (9500btu FAN UNIT)
MSXY-GA13VA X1 (12000BTU FAN UNIT)
Cost $2963

d) Mit H sys 3 inverter r410a
SCM60ZG-S (25590BTU) compressor
SKM28ZG-S X2 (9553 BTU FAN UNIT)

the above Daikin uses R22, thus cheaper, yet lesser maintenance n problem. now R410 still very exp in terms of gas itself. so would recommend using R22 system now.. although the total price is abit exp, but i tink its worth it. Daikin only makes aircon, i believe it shld be better than other manufacturer. not sure wats others opinion..

Thanks for digging out this info. Mitsubishi Electric looks good. I want super powerful blower in living. This model got much more power than others at similar price. Its also inverter type so should be electricity saving. Got any other catch?

Can you also tell me where you got this quote from? Includes installation?

Hi,
Go to web search under "coolserve"...it is a air-con company. All the quotes are for reference. In fact, you can get cheaper by $200+ outside BUT not sure what constraint they have. Treat it as a guildline for price between models and makes.

I did ask them to service my air con before, and their service is "very very good". I will buy my air-con from them if their prices are lower BUT, with all the additional cost eg. $100 to remove my old air-con etc. all-in-all, i need to pay an additional $300+ as compared to G...C..., so I go toward G...C.

Hope this help.

Living room photo on my reno blog...
wow...wat a BIG living room!

as u said tat recommended is 26,000btu for your living room. but from the above reference, tat is 12,000btu only. normally 12,000btu is for bigger bedroom.

actually i got a few suggestion to let u choose.

1) install back wit 2 fcu in living room. each 12,000btu, so total is 24,000btu. tink shld be able to cool the living room.

2) install only 1 fcu. since the living is big, tink u need 2.5Hp to 3Hp fcu..if u scare not able to cool the room fast, than get 3Hp.. but make sure the compressor able to provide the 3Hp fcu..(look at the btu)

3) install wit 2 condenser unit(provided enough space for 2 condenser unit). system4 for bedroom, system1 for living room. in this case, if u wan to whole hse to on aircon at same time, no problem one. for above 1 n 2, u only can on living room or bedroom.
