There are 2-3 companies are leading in market for Domestic use of AC, and Hitachi is one of these companies. I have Split Hitachi split AC RU512HUDD for my room. it’s 1 ton with 5star rating. there is not even a single thing to mention I hate about, believe me friends.ya but I feel bad for no display in my AC this is perfect for 9’x12’ room or 12’x12’ room. this is energy efficient. Hitachi’s all model justify their price. you even use this product for commercial use. let’s talk about maintenance, you guys need not to worry about. at the end like all other happy clients of Hitachi I personal Recommend
