I am using the voltas 1.5 ton AC since 5 years and I want to recommend it to all my review readers because the satisfying service I got from this machine says me to do so. I am using it since 5 years and I have not go to spend a single penny on this except periodic AC service every year. Its cooling is awesome and same as the day I bought it.service network of voltas is very wide.voltas AC is suitable for domestic as well as commercial use.It gives you the same benefits like bluestar and carrier but in less price.Go for it buy it.
