We have brought Blue star A/C 1.5 ton recently, it is awesome, it cools the room in less time. Even It consumes less energy. No noise disturbance. Even while blow is turned on, noise is less than ceiling fan. if you turn off your a/c’s LED display, one cannot recognize that a/c is turned on. It as copper tubes for Indoor unit as well as for outdoor unit which makes me to feel good. This product as different modes like Auto, cool, dry, fan or heat. However, Fan or heat modes can be used for heat pump products only.
Over all it is a worth product for it’s price.
