I personally would not recommend to buy this AC from voltas as I have a bad experience with this product.
The service and support was not very fast and good, after I purchased the servicemen took almost a week to come and install it.
Plus the product kind of make sound a lot and is perfectly audible during nights which disturbs the sleep sometimes. Cooling effect is good, as I have not experienced any problem with that.
Quality is below average as the sound is irritating. It is durable as of I haven not faced any breakage or in working problem.
Considering everything I think I lost a few money in buying this product. I would not recommend it.
