I had just bought this AC two years back. Since then I had been having trouble every summer. needs to refill gas on frequent basis and there is no leakage aswell on compressor. And when there is less cooling the electricity bill just doubles every month. So it requires a frequent check and cleaning very often otherwise it starts consuming lot of electricity. I would suggest to go for a better AC brand with good star rating so that it doesnt cost much on bill every month.
