I purchase hitachi 1.5 ton a/c three years ago.Last year I take AMC from hitachi co. After 9 months I call in hitachi co for service but there is no response from service centre, after two days I received a call from service centre there they says there is gas leakage problem in your a/c.l told them that l have no problem in my a/c and I only want washing service for my a/c in AMC but they says that if you don't refill gas in your a/c we can't do any work in your AMC
