Hii guys, I have been usin this air conditioner for a year but no problem have existed so far, the voltas company’s ac is realy worth relying on. it remains for the room of the normal size, which is not too big. apert from this, there are many features in it such as anti-bectirial filter dehumindifier etc. apart from this, it also offers a good guarantee. so if you want to buy an air conditioner for the room of a normal size, then buy voltas.
