I purchased Voltas 1.5 ton split inverter A/C last month. It's a very good product. It is so quiet that you don't even realize that it is working until you look at the screen. A/C produces no or little sound while working and does an exceptional job in cooling the room withing a few minutes. I am very much satisfied by the A/C but there are a few things I want you to know. All the Voltas A/C remotes are identical so there would be listed many functions that aren't supported by the model. It's no biggie but kinnda feel disappointed to know that you spend so much money and you don't get the features your remote says. A/C doesn't have option to chose warm air for winters ( as I said earlier the remote lists it) . This product is good but the service center support isn't good. Since the very first day that I purchased my A/C Iwas facing an issue with the connectivity. Remote didin't properly interacted with the A/C at most of the points in the room, I had to align the remote in a straight line towards the A/C then only it worked. I filed several complaints regarding this and service center representatives visited late and weren't able to provide proper solution even after so many calls. It has been two months now that I finally got the solution to the problem. Other than that, this is a very good air conditioner. I can totally recommend it to others due to its quality however the service center support ruins the quality if the product.
