I bought this Bluestar 1.5 ton 3 star AC last year from the local shop. After one year, I can say that Ive been very happy with the purchase.
The ACs cooling is very fast and proper. It has various modes to choose from as per your preference, eg. sleep mode, turbo mode. and dry mode. It also has a dust filter which is quite useful indoors. It comes with the Copper tubing which prevents corrosion unlike Aluminum tubes. So this is another plus point.
I didnt expect much cut-down on electricity bill but even with 3 stars, this AC does a pretty good job in saving power. My power bill never exceeds 5k per month, even with geysers and 2 ACs!
In one year, weve only got its servicing done one time for cleaning the filter. No other problems have occurred.
