My worst decision of life to buy a Blue Star Split AC..I had purchased the AC in 2017 ..Since then its cooling coil has been changed..Gas has been refilled several times..this season again it has faltered .i would urge everyone planning to buy a Blue star product not to buy it.3rd grade engineering quality..pathetic service partners..Never ever go for Blue star..they are cheats, frauds and bunch of jokers..no word to describe the pathetic condition.
