Performed cooling maintenance on a 19yr old Ruud split system Changed 16x25x1 filter Put Condensate treatment in the evaporator coil drain pan Drain is not trapped, which is incorrect from time of installation Potential water overflow is a risk from not having a trap Store owner has never noticed water leaking Got on the roof Condenser coil is not in need of a cleaning R22 refrigerant charge appears to be starting to go low Low voltage control wire has UV sun damage Wrapped control wire with electrical tape to prevent wires from becoming bare and shorting out No complaints of the system not cooling properly in the hot months When it comes time to replace, recommend installing a heat pump to help with electric costs during heating season
