My friend purchased the voltas 1.2 top star 155 cy split air-conditioner on last year .this was a gift for his parents to beat the summer heat.the summer is over but painful ordeal is not. my friend was told voltas product is good but service is horrible, but as a product is very good cool, very effective, but it has aluminium codenser, whose life is low, low electricity consumption very good quick cooling low noise, some issue with service but its very good product, value for money, buy this product thank you!
