Thanks for yr advice. I've just spoken to a dealer and was told the wiring for the inverter and non is different, so need to prepare properly otherwise installing an inverter set in a normal wiring system will not render the inverter mode effective. Also need to check the piping, for Daikin, whether R22 or R410 system, so need to ensure before buying. Most of the time, installers will just do a R22 system, but wiring for both these systems is still the same. Just found out that the price for the new R410 system is the same as the old R22, why? Because normally, users would want to buy this new one, but because piping done is not prepared for this system, so need to change back to old R22, therefore R22 is selling very well. Which thus cause Daikin to drop price for the R410. As R410 uses enviro friendly system, now I pening 
whether my installer have already embedded this new system for me, otherwise I can only use the R22.
As for the issue of choosing between an inverter or non, I'll decide for the bigger Hp inverter, so the motor will not be overworked to achieve the preset temp. In the long run, there will be more savings, but in my case, may take a longer time period coz I don't use it oftenÂ
. Now is to check for the piping to decide betw the R22 or the R410.
R410 is the newer and future gas to be used. whether my installer have already embedded this new system for me, otherwise I can only use the R22.As for the issue of choosing between an inverter or non, I'll decide for the bigger Hp inverter, so the motor will not be overworked to achieve the preset temp.

. Now is to check for the piping to decide betw the R22 or the R410.R22 is going to be obsolete. It will be not allowed to be manufactured around 2020, if not mistaken (I forget which year).
Most inverter out there are using R410.
Since R410 need a different piping compared to R22, as R410 being run at higher pressure, which need a thicker piping.
R410 may incur a higher installation cost due to piping/wiring cost + gas itself more expensive than R22.
So if with concealed piping and wiring, please check whether the piping and wiring is suit to inverter.
If not, a replacement of piping/wiring may needed before hand if one intend to install inverter.
Yes, it is important to check the room need how much Hp, an underpowered inverter air-cond won't able to save the electricity that inverter is designed for.
