Your house is indah residence, right? I almost buy one in November last year, they were selling RM380K at the time.

If you don't use your air conditioner for more than 8 hours, or like to set your temperature below 20 degree, then you don't need to buy inverter type, it won't save much. for me, I just want to buy one inverter air conditioner in my bed room, from my survey, hitachi is the one that has pretty good EER, can save more money in long term.
