I had bought voltas wac air conditioner in 2017. it was very expensive durable and without help of mechanic you can't install it because it is very tough to install. everyone know voltas is a old brand so I was think nothing is goes to wrong with my ac but I was sad because it was not true when I was going to star it couldn't be turn on and after start it was automatically turn off. I was disappointed to see it's condition. air quality of air is also fallen badly with time to time so I suggest you guy's air conditioner of voltas brand is not good . Please don't buy.
