2004 Lennox AC is operating properly, but in fair condition and showing age. 16x25x1 air filter in good. Visual inspection of indoor coil. Flush drain pan and drain lines. Run test unit in cooling mode from thermostat. Outdoor disconnect was off due to previous fan issues. Once inside AC electrical panel, a rodents nest was found and many of the low voltage and high voltage wiring was chewed up and showing bare wire. Performed wiring repairs to remove damaged wire and reconnect. Due to age and condition of contactor, we replaced that aswell wich is a candidate for why the fan would not shut off. After wiring repairs and contactor replacement, test ran AC to check refrigerant pressures. R-22 refrigerant pressures are within spec. Exact pressures and temperatures on photos. Dual run capacitor is within spec. Condenser coils are in clean condition. System is operating properly, but due to age, an estimate of lifespan cannot be said. Recommend preparing for replacement in the near future.
