I would strongly recommend not to purchase any voltas AC as it is absolutely hopeless... I hv experienced and surely would not like anyone else to get into their trap of numerous features. I just purchased a brand new window AC with copper piping to avoid gas leakage.. But to my surprise it got leaked within 3 months of purchase. How ridiculous and bad it is to betray the customer’s confidence who actually trust on customer executives words who try to sell it. Shame on you Voltas management. Atleast have some dignity to recognize customers hard earned money which they spent on goods which are necessity.
