Very poor performance of Voltas 183DY 1.5 3 star rating. I purchased this air conditioner in last year than it became very noisy, and vibrant sound produced. Many time it’s became very heat up and smelling like a burnt of wire. So, I am very disappointed in this Voltas 183 DY 1.5 Ton 3 star rating of air conditioner. So, I gave only one star rating review for this disgusted product of Voltas. In future, again I am not buying any products of this Voltas company. Voltas servicing is also very bad and disappointed.
