I bought the AC 4 years before , with 3 years warranty . It hardly worked fine for 1 year and then it stopped giving cool air , it automatically shut down , I asked the customer service , they came and said that there was a fault in my current but I already buyed the stabilizer , I had given them 2500 for repair but again the problem started after six months . One month before my Ac has stopped working , no help from samsung .It was a pathetic window ac I bought .I would recommend all of you to but ac from voltas daikin hitachi or LG but not from samsung
