If you are getting new aircon, try either Toshiba Inverter (using new type of gas which is more efficient). My sister installed this and it cools down her place very fast, very impressive. Mitsubishi should be pretty good too.

But give Daikin a miss. I am currently using Daikin inverter and I am not impressed by its performance. It cost more than the rest of the brands and yet not as good.
