Voltas Ac is not good if you want to buy for long term that is for more then 5 years.
It works well upto 3 years but after that the maintenance cost increased gradually and then the cost becomes unbearable.
Voltas is a product owned by Tata group I m really disappointed with the products of viltas as it is not able to set benchmarks.
Voltas is only surviving in the market not doing well and that is only due to the brand name of Tata group.Yes it is comparative cheap with its competitors but not great to buy.
For long term purpose you should definitely ignore this product but for short term you can buy this product
