OYL manufactures York under license. York is owned by Johnson Controls worldwide. Acson is OYL's "house brand" I think

I think the price different is about RM500 for inverter and non-inverter. If you use it properly, you should be able to recoup back in 12 months in terms of reduced electricity bills.

All air cond have a function : timer to on and timer to off. How come you don't know on this?
As said, state clearly in the first place would be the best. As inverter won't really save if the duration is short.

Kena washed before? Again and again, don't simply label or accuse.
With your usage, the bill shall not be above rm200, but your are rm300-400? So, your logic fails at any 1 time.

i can confirm kimsim's statement. inverter will almost straight away produce savings of approx. 50% of electricity IF you dont underdimension the A/C (i.e. if the inverter doesnt run under full load), start/stop is not the main point btw.

You can savely assume that you will cut down electricity for A/C by 50% no matter the duration you on it for.

Given the tariff etc. you can quickly calculate how much you safe. Even if you plan to on just 3 hrs. per day, you safe  approx. 25 sen for 1 HP per day. I.e. annually you safe approx. 100 RM. Inverter aircon life is longer than normal aircon, you can assume 10 yrs easily. So price difference 500 RM - simple payback for 3 hrs usage: 5 yrs, simple savings in your pocket: 500 RM on top.

for 1 1/2 hours you still break even during the normal lifespan of the AC and you do good for the environment. If you never on the aircon, no need to buy also right. So I dont think you will use less than 1 1/2 hours in real life.

Normal usage is probably more like 6 hrs average, so simple payback is 2 1/2 yrs. so of course you should take inverter. Only ppl with too much money to waste wont buy an inverter. I am not that rich, so i buy inverter & safe.

For 24/7 your savings lets you break even after approx. 7 1/2 months. So the more you use, the more you profit from inverter. However for any usage (other than using it like display and never ever on!) you will safe with inverter in the long run.

Maybe we should wait the inverter fanboy clarify on this.
Set at 18C won't do much help, only the piping will freeze.

Like I said, when BOTH running full load, non-Inverter uses less electricity.

Inverter works on DC current.
So have to convert our Tenaga AC current to DC current before use. The lost due to conversion is between 5 to 10%

Thanks PJusa =)

last question of the day tomorrow i will go purchase my inverter lolz
my room is 12 feet x 12 feet x 11 feet ceiling height,
room facing north, 2 adults in the room... is that 1HP is good enough? i dont want asked shop they sure said 1.5hp better cause the can earn more...
im asking them for the calculation non of them can proof that...

oh... cut it short means 1 HP is okay for my room size?  and yes im very sure of the room size... and yes im going to use R410a instead of R22

I notice Inverter compressor sounded different from non-Inverter. Anyone noticed that?

I am not talking about loudness. I am talking about the tone being different.

The tone of Inverter compresser sounded more like jet engine.

I notice "inverter" or partial load starts coming in after 15 minutes switching on. Once it did that, I notice the TONE of the compressor changes to sound more like jet engine.

thanks for the feed back now i know what i need haha...

oh ya normally the shop quoted the price with installation c/w 10m copper pipe...

but not included the insulation is that norm way ?

and the power point is not included as well as the wiring from the compressor to power switch

ya include bracket... power point not included as well...

some reading to understand =)

well if you understand this, u may do it... but take note u die dont blame me... lolz my home socket and fan installed by myself lolz...

very easy actually.
