should not be a problem

100% New :

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 often  . Now is to check for the piping to decide betw the R22 or the R410.

Wiring different for both. Piping for r22 & r410 are different. Both these are inverter, but different types of gas. Most installers use the normal piping, which can suit non-inverter and the inverter R22. Whereas for R410 inverter, piping is different fr the other 2. This is what I gather fr the dealer and my installer.
