HI every one I bought VOLTAS 1.5 Ton split AC that was working very good I am very happy with that actually I have taken this product for my parents, I feared they cant take care of maintainance since 1.5 years I didnt get any repair every day they uses that thing company executives have come and filled some gas so product was very good thanq voltas thats really awesome this thing also having option auto cooling I mean to say if room temparature is cooled automatically ac will turn off when the room temparature is heated ac will turns on
