Went around a few air con supplier querying about a new set of system 3 to replace existing. After much hunting, still went back to my last installer due to reasonable price and good workmanship. The lady boss , Mrs Ang is friendly and gives good advice. Settle for Mitsubishi Starmex Inverter 3 eventually, upgrade from LG non inverter currently using.
