Hello friends, I bought this AC last summer and after using it for about one month I have to say that this is third class AC with poor service and the cooling is very slow and cannot be used in big dining hall, and also we have to pay for installation which is free of cost in the other brands after using it for few months it starts making noise and some problems like water leakage, water is coming from air passage and the compressor gas gets empty in very less time and electricity usage is very high.
