Voltas vertis 1.5 ton compressor consumes very much energy with respect to cooling. Service and support of voltas is good but quiet slow. Cooling is not so fast it takes a certain time to cool the surrounding but cooling is good and produces a bit large sound which I must say as a drawback of it. Quality is not good in comparision of other voltas compressors and also not that much durable. Value for money for this product is 3/5.
