Thanks thesingingbard for the post of inverter.

Hi All,

i called coolserve in the afternoon. spent 15min to talk about my need & their product & service. Gave them my email, and they had forward me a quotation.

Hi Chunliang,

coolserve ppl mentioned that i may need to check with hdb, to place outdoor condenser at service balcony or must install bracket. But they offer a site visit to show me how the piping run.
Bro mypj_88,

Is coolserve using Armaflex as well as better copper pipe?
I went to ask GC and they give G-flex and if want to top-up to Armaflex and better copper pipe, it will cost me another $180, so overall is $80 more ex than coolserve.

Did you checkout Hong Tar?

Who did better job of installation: Hong Tar, Gain City or CoolServe?
So it wont leak and less problem for next cool 5-7years?

Hi Bro. Mike,

In the quotation, it stated standard installation. Additional charges for copper pipe more than 15mtrs per FCU, and thicker insulation will charge $80 per FCU. I had replied coolserve's email to ask for the materials used.

By the way, the price from 3.6k+ - 3.7k+ quoted for system 4 inverter-Mitsubishi electric - Daikin - Toshiba.

I dont know about Hong Tar. Maybe you could give me their contact, I will call them.

Hi Chunliang,

Thanks for the HDB link. I had check before, but dont understand. Because my service balcony is beside 2 toilets. No direct link to rooms. Not sure how the pipe run. Will arrange coolserve to have a site survey, if confirm to use their service.

My Fujitusu aircon sucks!! The single split AOAR18JCC inverter in my bedroom broke down 2 times within the 1st yr. It was installed 1 and half yr ago. Now the mulit-split ASAA12JACM inverter in my other 2 rooms broke them last Friday. They are less than 2 yrs old. The service of the agent - Winfinity is real
disappointing. I'm always put on hold on the phone and they always say will call back and in the end i've
to keep calling to get to talk to their person in charge. Upon checking yesterday,the technician said both the PCB and 2 EEV coils need to be replaced....Sian.. It will cost me almost $600 including $80 transport. There is only 3 months' waranty after the replacement. I questioned them how can the air-con can break down so soon. They say other customers have no such problem. Last time my Toshiba air-cons lasted for more than 10 yrs without giving me much problem. I regret v. much changing to Fujitusu inverter thinking i can save on the electricity bill. I wonder if inverter air-cons are really less reliable or it all depends on the brand??? Should i get the replacement done ? Don't know how many months they can last and get another replacement again. I would rather change the whole air-con set. When air-con breaks down, it's not just money, but time to wait for them to come, this and that, and causing us such inconvenience - for the whole week my daughters have to sleep in my room, sian....
My Fujitsu aircon also sucks. PCB gone after 4 years. I've been unhappy with this aircon since day one.

thks everyone here for good info & advise

finally got the toshiba sys-3 non-inverter installed last week.. installing aircon with so many furniture inside was really no joke, like a war zone.. :p

so far so good, the 9k BTU unit is okay for my small 3room flat living room. for the FCU in living room, due to the low ceiling and high door, the gas and water pipe is separated into different trunk - the gas trunk goes upwards above the door, the water trunk goes downwards around the room.

one observation so far is that when the MBR FCU is running on 'quiet' mode, i can hear very soft 'whoo whoo' sound coming out from the trunk (can hear it better when i press my ear to the trunk). has anyone experience this before?
