dear all.. need some advice..
i'm currently thinking of wat aircond to use for my masterbedroom and my living room. I've already layed the normal 1.5hp and 2.5hp copper pipes.

For the 1.5 hp for masterbedroom, I've got so many contracting advice from different aircond installers.
3 installers told me not to get Daikin Inverters as servicing it is a real pain and expensive. Plus it's not really running on inverter technology as it's running the old R22 gas which i don't think is true as inverter technology is not gas based? Not sure who is correct as only one other installer told me Daikin and Mitsubishi it's good (he sells all brands)

So far i'm thinking of getting the Mitsubshi MS-GF13VC 1.5hp (basic) model or the MS-FF13VC (with triple plasma filter) or the Daikin FTKD35DVM Inverter. Any users out there who has experience using both brands?

Anyone using the Mitsubishi MS-FF13VC and how is the electric consumption like as that is rated 5 stars electric effieciency.

I've already layed concealled copper piping for non inverter models. Can i use Panasonic deluxe inverter with such piping?
