Bluestar is a brand, and they are maintaining what they are. Coming to service and support its really nice and cooperative.
As it is split ac it should not have the sound when its turn on, and yes it doesnt have the noise at all coming to cooling which is really good and easily manageable. It is having user friendly remote which we can use to control this device.
Taking about its reliability which is really great, one of my friend suggested me to go for bluestar and I am really satisfied with this AC.
U will find different different amount in different shops which will be up and down by 2 or 3 k. so I will not tell you in how much I paid because you can negotiate. But overall it is value for money I must say.
