all this five ticks is nothing but scams/ the technology is the same just that they cap the horsepower. it is like the older AE86 car at 1.6L can give 150hp while the current 1.6L car can give only 110hp. the AE86 can yield 14km/l if you cap its horsepower to prevent it from going into fuel guzzer mode.

basically u paid more for capping your aircon real power.

now with capping of the power it means ur air con is not able to support 3 FCU at max capacity as before. it also means u have to pay more to get a higher capacity compressor for something which is not needed if the power is not capped. so basically the benefits goes to the manu and i see no sense to paying more for less power

If you want energy saving, then get this. 5 ticks.

However take note that it's capacity is not sufficient for all 4 to turn on at the same time. (you can, but It'll take longer to cool. Or, on simply don't switch them on at the same time. Wait until one is cool then on the other. Cos the initial cooling phase is the one that requires most energy)

In just using it as a gauge. I'm not from coolserve

now this is the F part. the compressor is not able to support 4 fcu at one time, next the compressor are forced to worked harder to generate the same power so the compressor noise is very loud for this model and also i forsee easier breakdown as the fans are made to spin harder for the same juice. more repairs and lesser product life at more expensive price.

i m more inclined to get the 3 ticks as i can see why i will incurred more $ if my aircon is not turned on at lowest temperature but > 25 degrees

Basically, everything said above is true.

If you prioritize on low electricity usage, and able to accept slower cooling and not so cold for all rooms (25deg or above) , then the 5 ticks is recommended.

But if time taken to cool, a rather low temperature (below 25 deg) , are what you're after, then go for something 3 ticks perhaps

thank you for all the feedback guys!

not all 4 aircon will be on at the same time for sure, so i dont think there's an issue.

i think cost is the one that is most impt, other than that there isn't much issue..

That's why I go for the LG's 3 tick A4UQ30GFA0 compressor. It's much cheaper than the japanese brand of similar class rating.
Rated 40K, BTU max.. Comfortably able to support 3 system, with 4 still got some margin..

Your prior reply says all 4 will turn on without fail, that's why advise you to get a higher rating compressor, so it won't struggle much.

priority should be savings, only turned on at night, for 8 hours at most. all 4 units will be turned on for sure without fail.

I don't recommend LG. I have heard from multiple sources that there's quite alot of complaints and malfunctions for LG aircon.

Of cos its price is much cheaper than the rest in its category. So that's the catch.

Do some basic calculation. Get the price difference between a 3 ticks vs 5 ticks model.

Then look at their annual electricity usage (look at NEA numbers ) and calculate how many years you take to recoup the difference.

From there, make a decision...

Ordered liao. Will see, and keep finger cross. Good thing is it has 5 years warranty on all parts, not just the compressor. So first 5 years there's some comfort there.

I see. Good luck and hope it's all good for you!

I guess I misunderstood, I assumed that the cooling will suffer if all of them are switched on at the same time only. The case for my family is that the aircons will be switched on about an hour or two after each other, but kept on for the whole night.

What does "higher rating" refer to? I'm quite lost with all the terms here to be frank!

@serverxeon : thanks for the suggestion, I will do!

[serverxeon]

Higher rating refers to higher cooling capacity. Usually expressed in kW or BTU/hr.
For system 4 you're probably looking at somewhere around the range of 10kW or 34,000 BTU/hr. That's the heat energy per unit time your compressor can remove. So higher rating is more powerful in layman term

because of NEA set higher requirement for the ticks?

Yup i am surprised LG giving a system 4 compressor for a system 3. the extra power will be helpful if needed. A4UQ30GFA0 is 3 ticks

I am trying to get this same system but upgrade to A4UQ30GFA1 (4 ticks). I am willing to trade some power for some saving capacity yet will not strain the compressor lifespan.

A4UQ30GFA0 (5 ticks) is too expensive upgrade with abit too much power cut. Yup i am supporting 4 ticks. 5 ticks compressor giving alot of problems as what a installer told me. he said the 5 ticks has more RMA even for ME system.

well still a scam to me. paying same thing but much more expensive for a device that cap the real power of the compressor is silly to me. i wonder NEA ruling is for the ppl or for the companyies. just like DBSS which is to help the mid range construction companies to squeeze money from the ppl who wanted to upgrade their flats.
