Voltas id a well known brand in cooling and refrigeration.
And likely with this product I brought this in the month of May 2017 and the product uptil now
has lived upto expectation.The Five star rating is genuine and it really keeps a check on the electricity bill with 5-6 units consumed over the night.You have to wait for sometime till it is installed .I got it installed after 3days.
The cooling is good covers good area and the sound is very less .As mentioned some 40 db and is quite silent.Moreover, the service provided by Voltas is excellent with instant 24 hrs problem response.hence at this cost if you get split, its value for money.
