I have purchased 2 ton 2 star voltas ac 2 years ago till date AC has no complaints. Service is good. Everytime we call custumer care they arrange a service with in one or two days. 2 tob ac covers area of lobby and a room. I love this product and I love the service provided bt company. Voltas uses good quality of plastic and equipments. 2 TR AC is value for money. Its look is simple and awsome.i am really satisfied with this product. It makes little bit sount bt that can b neglected if they are providing us suck good service
