I have a daikin FTKP50PRV16 1.5 TON INVERTER AC
So far it's pretty good, no noise in auto mode. Always buy a bit higher capacity for inverter ACs.
Newer standards of 5 star certification for inverter ACs has been announced, buying according to that standard is better to get a considerable savings over 5star ACs.
Either way Daikin is a better choice IMHO, it uses a better 410a gas. Stick to tested AC brands like Hitachi, Ogeneral, Carrier, Bluestar etc
