Performed cooling tune up. Checked all major components and system operation. Flushed drain line. Cleaned condenser coil. Customer using 2 16x12x4†air filters and EAC prescreens. Removed prescreens and advised customer not to use them anymore and to use a 16x25x4-5†filter instead of 2 filters to avoid filter pass-by. Replaced filters with filters provided by customer. Found lots of rust in furnace, on evaporator coil, reversing valve, accumulator and compressor. Ducts are very dirty. Blower wheel is 50% impacted. Evaporator coil 75% impacted. No flood protection. Compressor pulling high amps on start up. Compressor and condenser fan motor capacitors failing. Restriction in piston causing high head pressure, high subcooling and high superheat. System is 25 years old and uses R22 refrigerant. System replacement is recommended due to age, condition and estimated costs of repairs. Set up appointment with comfort specialist for tomorrow evening to discuss replacement options. Recommen
