Hi, Voltas is very good brand in a.c and has a good reputation as a company. I bought Voltas Vertis 1.5 ton A.C 7 years ago. This literally chilled your room. As compare to other brands, this a.c came at very reasonable price. Easy to use and operate. In the starting years, it runs very good and I do not have to spend any money on it. But after 3 years, its compressor become faulty and I had to spend around 2500/- on it and after that a.c chills the room again. It is a good option to buy. Thank you.
