I heard Daikin only has 1 motor? is that true?
There are some compressors having 2 motors, and the 2 motors type is said to be much more long lasting since only 1 motor will be on if it is for 1 room. so more efficient. Not sure how true is this as well.

I am also looking for a Non-inverter Sys3, still trying to look at which brand is good.
Any recommendations for Sys3 non inverter?
yup.. under "compressor type", if there got "TWIN" word, means is 2 compressor inside. if didnt, than it is one.

having 1 or 2 compressor inside, it depends on yr usage n also hav advantage n disadvantage too.. but than getting one wit 2 compressor inside consumes more electricity.

Hi all,

I would like to buy new aircon for 3bedrooms + 1study room. 2bedrooms will be using 8hours+, then 1bedroom + study room will not be using frequently.

My unit already have 40Amp main incoming. Condenser got to install with bracket. Could I install 2sets of system 2 aircon, or must get a system 4 aircon?

How much HP should I look into? Thanks.

those wit 40amp, max is 2 outdoor unit.

does your house hav aircon ledge or service balcony?

but than if sometime u wil be using the 3rd bedroom n study room, it would be efficient to hav system 4.

Hi chunlianghere,

Thanks for respond. Ok, i will look into system 4 inverter. Any model to recommend?

My unit has a service balcony. Doesn't it mean, condenser need to place at there to save bracket cost? Because I saw other units install at outdoor with bracket.

Thanks again.

u can choose to install bracket or not to install in service balcony. jus need u to know that if u wan to install outside, u hav to get approval from HDB, which means quite troublesome.

becos service balcony is inside your own house, so no need approval one..

Guys,

Need your expert advice here

I am deciding between:
Daikin - Inverter Sys-3
3MKD75DVM / 3 x FTKD25DVM
3 x 7,847Btu/hr
$2,708.00
with $150 Trade-in -> $2,558.00

OR

Daikin - Non-Inverter Sys-3
MA56EV1 / 3 x FT25DVM
3 x 6,073Btu/hr
$1,914.00
No Trade-in

My usage pattern - only at night - 6-9hrs per-day, 1-2rooms at a time.

And what pipe and insulator should I choose that would last at least 5-7years?
Appreciate the reply ^_^
from your usage pattern, getting non-inverter is gd enough. actually default installation from manufacturer is gd enough, which can last many years. but if u wan to feel safer, than 1/2" insulation.

IMO, gettin non-inverter is better.
firstly, becos from the whole nite u on the aircon, there is some time can let the compressor/outdoor unit take a rest.
secondly, it can save u $$$ when there is problem wit other parts after 1 year. n than the ppl who knw how to repair/very gd in repair inverter r very few. so if u suay, than it wil become more worse.

but well, if u feel tat inverter r better n tat u like more functions built inside inverter, jus go ahead ba. i nv say inverter r not gd.

lastly, it depends alot of things, eg. usage, system-?, n many other factors.

Thanks Chunliang, from ur replied to me, I know I have few options to mount the condenser.

But from ur replied to Mike, could I get a non-inverter system4.
Master bedroom + 1bedroom will on aircon at night 8hours+, but 1bedroom + study room will not be using aircon frequently.

But there are chances when all room using aircon together.

Thanks bro!

I might go for non-inverter most probably, as I have inverter for my living room, and I dont see much diff in terms of cooling nor other feature that non-inverter doesnt have.

mypj_88 bro , changing your aircon as well isit? Mine I think almost 10years leh.. current sys-3 brand is National, too old already
Another alternative is, do it like my setting: get sys3 for bedroom and sys1 for your living room.

Time to call those shops!

but if u were to on all the room at the same time using non-inverter, Daikin MA56EV1, it wil not be very cool, n wil take a very long time to get to the temperature. UNLESS, u on 2 room 1st, than an hour later(depends u set wat temperature), u on the rest, than it is ok..

but well, like yr normal usage wit 2 rooms every nite, n sometimes all the rooms, it is alrite to get tat.

Coefficient Of Performance

the higher the number, the better efficient and better performance.

Hi Bro. Mike, me juz brought a resale flat. Only master bedroom come with aircon. So thinking to install aircon for 3bedrooms + 1study.

I tried to talk to gain city, but I cant tahan their attitude. And I found the forum . Think I should call coolserve to compare inverter & non-inverter.

Hi Chunliang,

Thanks for your help.
