I am using this blue star cnhw18raf 1.5ton air conditioner since 2015.and now I am sharing my personal experience through this review to you.I bought this ac from blue star dealer and it costs around 35000rs.The main advantages of this ac is that, after you start the ac it starts cooling rapidly within just 5mins.It makes your room tempreature comfortable within just minutes.Moreover it is energy efficiency is good.which means the light consumption of this air conditioner is very less.I normally use this ac for around 12hours a day and my electricity bill costs me around 6000rs month which is quite affordable.Using it from 2years and still not faced any trouble yet.blue star is a good company with great customer care support.Must buy this ac, worth your money!
