This voltas 1.5 ton 3 star ac is not a performer ac , its a average one where you may see problems within one year or two year after purchase of this ac. Its have good brand but this particular is not good at all. Rear fan of ac creates lots of sound which is dosturbing. Cooling frequency is not that good. The price of this ac is very similliar to other brand where we do not have any issues. I have only issues regarding my ac unit and its remote. Remote of this ac not work properly where on/ off button is not working. Takes lot of time to cool our room also sometimes we faced gas leaked from rear side. So this paricular model is not recommand for anyone.
