I brought the Voltas AC a year back. The product is not that good both when it comes to service and performance. After using this only for 2-3 weeks, there is considerable reduction in cooling. Even after running the ac for 2-3 hrs on 20 deg there is pathetic cooling honestly. The manual given with the product is of no use and does not even answer basic questions. I had called up voltas customer care and they are even more ridiculous in responding then the product. They have registered the complaint but no one has come to take a look at this. There are much better products from Samsung and LG that customer should look for and not this voltas product.Also this AC makes much noise. When we start Ac it makes less noise but after that it makes considerable much noise.
