Recently my friend purchase this Voltas 185DZA 1.5 Ton. This is very good product and it cools the room within mints. But main thing the sound of the ac is very high in compare to other companies products. Its remote is also not so good when we push switch off button for 3-4 times then it works. After sale service of the company is good and after giving complaints we get quick response from company’s end. I will recommend this product to all my friends and knowns.
