I have purchased 2.0 Tons split A/C six years back and is in this period its PCB found defective two times without and reason.In summer season if repair time is long it is not bearable.Its repair cost is high and the repair is time taking. Of course is cooling is effective.I am not satisfied with such a performance.I have purchased a Hitachi refrigerator also and its PCB also found defective and its repair time was too long.
