I had purchased this AC in Jul 2008, since then I have been complaining every season for the non performance. I have a complete record with Voltas about the number of complaints I have made against the product, every time their so called Engineers come to my place and try to fix it. But till now the AC has problems with the cooling and compressor trips without mainting the temperature. I have complained about the same with Voltas Ltd customer service. I am totally frustated and think I have wasted my money towards a company which cannot provide services to their client. Please see as to what kind of help can I get. Whether the AC can be replaced or on the depriciating value the money can be refunded.
