I have 3 Hitachi at my home . In which 2 are split AC and 1 is window AC. I have 2 split AC because there no space in room sapce mean in that room there are no window . Split AC is expensive than window AC . And split AC has high maintenance cost than window AC . We have an advantage in window Ac it is that if we lost our AC remote we can make it start with buttoon but in spilt AC we can start it with button because split AC don not any button from which we can start . And the service of Hitachi company is good . So I prefer you all to buy this product . And colls the room very fast I appreciate .
