I purchased 1 ton inverter SPLIT AC in oct 2021 and started using it in May 2022.After 3 days, no gas and cooling gone. Raised complaint with Hitachi, which was resolved by Hitachi 10 days later by replacing condenser coil. And within 15 days leakage occurred and on technician visit we got to know that new coil also has leakage from the same place as earlier...AWESOME.. so total 15 days run in 3 month of Delhi’s summer.. Thanks to Hitachi for this sort of jerk product...
