Just came to know only after purchasing the samsung ac that how worst it is on the field of air conditioner.the cooling is worst only after a time spam of 1 month. even for I personally have to clean the vents latest once in a week, these a so prone to just at even on small amount of just is effecting the cooling. I am also using lg air conditioner on my other room which on the same conditions works like a champ.please never buy a samsung ac because if a brand can manufacture a hero like galaxy s7 edge in smartphone industry can also manufacture a hero in ac is just false.
