I purchased this voltas 1.5 ton 5 star silver color product for higher cost but I am very good satisfied with it because it working very good and service wise also they are responding very nicely till now no complaint booked for not working power consumption wise is better unlike other brands, free 5 years warranty given for spare parts except PCB, INDORE AND OUTDORE, because of coper condenser room is cooling very quickly unlike aluminum condenser overall I suggest you to buy for better comfortableness.
