I have Hitachi split air conditioner. I want to share my experience with you. The service staff is not so good. If you are using air conditioner you have to clean it very often mostly once in a month. There is red light which indicates the time of cleaning .In a split air conditioner there is a indoor part and another outdoor part. I usually call the service staff for cleaning as they recommended in their service manual . When they came they always clean the inner part but they never clean the outer part .My house is beside the main road so a lot of dust attach to the outer part but the service staff dont clean it.
It is really costly to clean the conditioner in almost every month because they charge approx 700 rs for every cleaning. 700 rs is not a small amount.
The remote of the air conditioner does not work well. Once I have probllem with the cooling then I called them, they came and said that everything is ok but they didnt even checked the gas pressure.
One good thing about inverter ac is that they consume less current compare to other air conditioner. Hitachi air conditioner cost a lot. you will get various other split air conditioner with this feature in less price. This is not a value for money product.
