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.
Safely assume. So is still based on general statement with no fact to justify, good take. So, I want to ditch all my non inverter air cond and change to inverter air cond. If it do safe me a lot of money as you assumed, I pay you rm1000, else, you have to buy the air cond I bought same price as well as dismantle fee. Dare to take the challenge? Now my bill is about rm50-70 a month. If after change can go down to rm20-30 that consider you win and you can take the rm1000.

agree as well, i also dont believe after you installed an air cond u will use 1 hour or less... in my opinion ,
once you installed the air cond, u will use it for sure even though you said " i will use only 2 hour / day " or something like that,
until the air cond installed, by not realize it you will switch it on once you feel the heat , by the time goes on the habit of get comfortable in cold room
u will switch it on every day u at home... haha.. thus getting an inverter will be good..
=)
my 2 cent... hehe
Well, choosing the right HP for the right size of room, with the room is well ventilated and using the right bedding stuffs, turn on the air cond for 1-2 hours is not a problem and using shorter period of time, your lung also healthier. But, this won't happen in big cities because of green house effect and also the flats built are meant not to have proper ventilation. So have to use longer hours.
