I have used Daikin (non-inverter) since 10 years ago and they are very good (normal 26C setting). My current inverter is set to about 25C, but I turn on the fan to circulate the air and to speed up the cooling process. My in-laws have used Daikin too and they are also cool enough (25C) and now I am changing them to the newer R410A after the MUP.
