This is a 1.5-ton non-inverter air conditioner. **The only reason for selling is the low voltage issue in my area.** I am planning to buy a 1-ton inverter AC. There are no issues with this AC. Both the indoor and outdoor units are completely fresh, with no rust, and the compressor or internal units have never been repaired. It was cleaned regularly. You are welcome to bring an AC technician to check everything, from the gas to the entire unit, to ensure it is in perfect condition before purchasing.
