I think it's only fair that old piping not under warranty. How can you do business giving warranty to and old stuff?
Yes but they cannot mislead us that re-using old pipings is ok in the first place. We don't mind not deducting the S$50 for each room and pay additional for upgrade of insulation. But the sales assure no problem that's why we go ahead.

I always go for "Sales know nuts".. take their advice as pinch of salt....

anyway, what I like from COOLSERVE is that their Sales is very professional, they don't oversell or make comments like normal sales person. I called them and spent like 1 hour asking all the question, and I only close the deals 4 months later (due to promotion). I go to COOLSERVE because their Sales/Customer Service didn't pressure you and didn't give black eyes even if i dont close the deal immediately. This is the kind of company you need to deal with for long term commitment like Aircon

Mitsubishi Electric

$3,700.00

MXY-4A28VA / 3 X MSY-GE10VA / MSY-GE26VA
4,367 x 3 Btu/hr + 12,487 Btu/hr
$3,740.00

price including install but without S/S bracket and power point.
What's the difference between what you mentioned and
- Mitsubishi Inverter Sys 4 MXY4A28 / MSYGE18VA + MSYGE10VA X 3 (18kbtu + 9kbtu X 3) ?

How come the Btu different?

Condenser Cooling Btu Models.
MXY4A28 model = 28,000 Btu cooling capacity.
MXY4A38 model = 38,000 Btu cooling capacity.

Indoor model also can be the Btu for usage per each room Btu.
GE10VA = 8530 for full load Btu.
GE13VA = 11942
GE18VA = 17060
GE24VA = 20472
GE26VA = 24225

For example here.
switch on 1 room = 8530 Btu x 3 = 25,590.
The total cooling capacity per each room can be up to 25,590 Btu so the balance left = 2410 Btu? cannot be.

if installed single split for each compressor can be support from the specifications per total Btu what you have.

because the total cooling capacity Btu to support by 4 units at the same times to switch on and then the actual Btu will be smaller and slowly to cooling down per each rooms, cause the total only 28,000 Btu may sharing for many rooms.

below is the chat to showing the total Btu to switch on at the same times.
it is the setting from air cond manufacture.
and may have runs on balance Btu per each rooms.

MXY-4A28VA / 3 X MSY-GE10VA / MSY-GE24VA
4,742 x 3 Btu/hr + 11,361 Btu/hr

MXY-4A28VA / 3 X MSY-GE10VA / MSY-GE26VA
4,367 x 3 Btu/hr + 12,487 Btu/hr

MXY-4A28VA / 3 X MSY-GE10VA / MSY-GE18VA
5,118 x 3 Btu/hr + 10,236 Btu/hr

MXY-4A28VA / MSY-GE10VA x 3 / MSY-GE13VA
5,800 x 3 Btu/hr + 8,188 Btu/hr

hope you can understand what i explanation here.

Thanks

Hi kimsim,

Thanks for your explanation. It's quite clear that the btu is limited by the condenser unit and the individual indoor unit.
Does it mean to say the higher btu for indoor unit, the faster to cool the room? With higher btu, will the cost of electricity go up as well?

I was recommended this for my 4rm setup. Will it be sufficient?
Mitsubishi Inverter Sys 4 MXY4A28 / MSYGE18VA + MSYGE10VA X 3 (18kbtu + 9kbtu X 3)

Thks!

Ya sure get higher Btu for the electricity is higher.
But you don't worry it is limits the amp at 8.5A for HDB flat so the total electricity at fixed to 1930W for limits if switch on 4 units at same time only Btu will be effect become smaller.

Below here I have some tips for the room size and full Load Btu/Hr

3.5x4m - 8500btu/hr
4.5x4.0m - 12000
5x6.5m - 18000
5x8m - 22500

It is do not over size room and choose the smaller FCU.
For long hours operates, will be more efficient for electricity.
Cause bigger FCU can be faster cooling and saving more power to load the Btu/Hr.

but normally bedroom using around 9000btu. living room around 18000btu.

for example if yr bedroom hav sort of "server" room, than higher btu is recommended lo..

Basically for the cooling capacity is equal to car capacity CC if lesser than <1000CC and below.
For the smaller car still can fetch up to 5 persons.

It is not must difference to compared as bigger capacity >1600CC car.

Only smaller car is over weight when driving stay in 5 persons to facing the problem is no power to be speed up for the higher slope area.

Will be what happening?
Change gear and feel heavy and no power to be pressing more petrol to force the car runs.

The result is used more petrol and like electriciy.

Just want to update:

After replacing old aircon with the inverter version, I am very surprised!
Now there is no more vibration/humming sound... so far very happy with the set.

Cheers!

Ha ha your feeling now is same with me few months ago,
I'm replaced my old non-inverter Air cond, after using inverter type I just knew the air quality and quiet and comfortable.

Yeah Bro!

Hopefully can save from the electricity bill...

If every month can save $50, so yearly I can save $600.
In about 5 years I can get my aircon investment back! hehe...

Just tried for 2 days... using the aircon at 23 degree really have no sound anymore from the trunking but the trunking is still WET though......

Going to call them again..
I really got bad luck.. today another new error appeared on my LG wall unit. Error code CH02. Cannot even start the wall unit .... sigh.. got to call them for repair.. 6 months and dun know come my place like so many times already

Wrote a long complaint letter to LG and Gain City but got no response (expected lah )

Update: Must admit quite impressed.. called up GC in the morning and less than 1 hour later, LG called to said they coming today. Came at 2 pm and then replaced (yet another) sensor in the wall unit. Said that a particular batch of air cons made in Korea (during a harsh winter) had some problems with sensor.. so hence my issue... oh well. just my luck

I am saving like 300 kwH every month by changing to inverter.
At current rate of around 25c, that means I'm saving 75 bucks every month.. hurray!
