Hitachi is the giant name in making Air conditioners. I was purchased Hitachi kampa RAU31HTD 1.5 ton split model 4 years ago and no complaint till the date. colling of this ac is awesome as my room size is average . 3 star rating reduced power consumption and the ac unit have low noise. Remote control comes with diffrent modes and features like automatic fan speed according to ac mode , dry mode etc .it have an anti bacterial filter inbuilt. Good responce by Hitachi service center for any query .
