Today the number of options for a good branded window AC are less. Hence this 1.1 ton compact size AC from Hitachi is a good buy. Its biggest feature is its efficiency as it has a 5 star rating. The noise levels are low too. How ever the price is a bit high but hopefully I shall save that money in electricity bills. Also some people tell me that service might be an issue but as I have just bought this AC I have not faced any issue till now.
