I use this Air Conditioner from last 8 months till now I don’t have a issue regarding this Air Conditioner, till now I did not face any problems of this AC like leakage of gas pipe, problem in fan or other problems and till now I did not fill the gas in the outdoor unit of AC. I have heard about this Air Conditioner from my neighbors. It is very Good Air Conditioner than other AC in this price range. Thank You
