Voltas produces all weather ac and had an amazingly fast cooling capacity A 1.5 Ton Ac is good for a middle sized room the exhaust of the air condition is very powerful so it makes noise but overall the air condition is a nice choice amongst all the brands present in the market so if you are going to purchase an split Ac go for voltas all weather Ac voltas is a renowned brand so you dont have to think much about it the customer service provided by them is very good they give instant response to your complains. I will suggest you all tu try voltas once.
