here's an extract from another forum
"Most people shun off inverter aircon because of the high initial cost but never think of the benefits. Most inverter aircon saves u loads of electricity, tested and proven. You would get back ur initial cost by say 2 years? or less? Inverter aircon is much more comfortable. Anyone has experience sleeping with aircon n always remove blanket cause too hot then put blanket again cause too cold. You won't have such problem with inverter aircons. I've got the following points to add.
1. Don't compare brands because of price.
Example: Brand X might offer you system 3 at $2000 and Brand Y offer you system 3 at $1000. Don't jump in and get Brand Y straight, check the specs. What's the cooling capacity of the individual fancoil that both brand offers. What's the capacity of the condensing unit. Brand X might be able to cool all 3 rooms when turned on where as Brand Y could only manage 2.
2. Don't compare companys because of price.
Almost like the above. Company X and Company Y both sells Brand X system 3. Company X quotes u $1000 where Company Y quotes you $1500. Ask for the specs. Company X might give u same brand but a low capacity CU or fancoil.
3. After sales service.
There's many china brands out there which is cheap and looks good but if they break down, are you assure that those contractors outside knows how to fix them? Spare parts are they avaiable? Go for well establisb brands which are known for their after sales service.
4. Installation.
Like someone mentioned, installation is very very important for an aircon system. No matter how good the aircon system is how expensive it is, if the installation sucks. Thats if for you. If you buy a particular brand, find their authorised dealer.
Lastly, ask urself what's the usage of your aircon. Only 1 room always on at nite? or all 3 run at nite? Or all 3 on 24hrs? All these makes a huge difference. Get a good dealer to recommend. They should do the job. Inverter is what i would recommend for sure. =)
Just my 5 cents worth.
*Note i'm not here to sell or promote and brands/company. No brand nor company name is mentioned. I've enough of people framing me when i'm just trying to help. "
"If there's only 1 of the 3 rooms that is on always. Inverter is obviously the choice. Why? Non inverter basically is stupid LOL. Only know 2 things. On and Off. So the compressor keeps on cutting in when the temperature is not cool enough. Inverter has a circuit board inside that is SMART! =) For a start it doesn't cuts in just like that, it gradually cuts in thus the power consumption is low n once it reaches the required temperature it doesn't shut down, it goes down to a constant and operates. The cutting in and out kills the compressor. Trying playing with ur room switch on and off always. =P Just an example for you. Lets call it Brand Z.
Lets assume you are using a non inverter system 3. Operating the aircon in 1 room would take 1490watts per hour. Operatiing 2 room would be 1520watts. Operating 3 would use 1600watts.
Now for the inverter one.
Running in 1 room would take 780watts(400-1050) . 2 would be 1550watts(460-2220) whereas 3 would be 1660watts(510-2100).Notice there's a ( )? Eg. Room 1. 780watts(400-1050) means. The average power consumption is 780watts. When the compressor cuts in it starts at 400watts, the highest it goes would be 1050watts. Once it hits the required temperature it goes down n uses about 780 watts constantly. Thats the magic of inverter. See the difference between them? Lets say u uses a non inverter n on 1 room for 8 hours a day? 1490 x 8 x 28days = 333.76kW per month. Which is rougly $53 per month just for the room. Inverter would be 780(just take the constant) x 8 x 28days = 174.72kW per month, which would be $28. That's a huge difference from my point of view.
Hope my example ain't that confusing. =p The power consumption i gave above is quite close to the actual spec of a certain brand. I didn't make them up. =) Just trying to give an example. It applies to every brand of inverter aircons. So its your pick. "

, the only thing u need to provide for them is some old newspaper
