I bought voltas 1.5 ton 3 star split ac in this summer. With in one month I faced a problem and its connector got burnt so I called the customer care and I faced the problem to register my complaint because its not connecting so I messaged to the number which I searched through google. So far it is working good and cooling properly. I had samsung ac before but this one is better and energy efficient. Company provide three free service within one year and five year warranty on compressor and its comes in variant aluminium and copper, I personally suggest to buy copper one its 1500 to 2000 more than aluminum but it has long life than aluminium.
