This unit is non inverter model, cause the gas is R22, you can try to change outdoor non inverter unit as any models or brand will be works fine too
oh, so just change the outdoor unit can liao ah... well, the indoor unit already quite old.. think might be a time to change also, so does it mean the piping for the old unit can no longer be used by the new unit?
