please take note of the catching part regarding electricity saving for all these inverter airconds.
it needs to be operated at certain temperature, say 26degree C for not more than certain hour etc....
else, it might not save you much money.
comfort are more or less the same for all brands of aircond (i'm using Panasonic, Hitachi, Mitsubishi, LG at home)
many houses install the living room aircond compressor units at car porch, my suggestion is DON'T DO THAT. Extend the refrigerant pipe longer up to first floor and install the compressor there. Looks nicer and no noise and heat problem.
