Tech arrived at a Free tuneup. Upon inspection, the blower capacitor was out of tolerance. There was a dead snake wrapped around the compressor capacitor and one of the wires were burnt. The condenser fan was pulling high amperage. The Delta and refrigerant was low. The ductwork and blower area was dirty. There was growth in the supply plenum. The coil was rusted and leaking (refer to video). There was no observed drain safety. The customer was informed of recommendations today. Due to age, condition, price of repairs and presence of R22; it is recommended that the customer speak with a Project Manager about upgrading to something more reliable with warranties behind it. He agreed and we will have to call his wife for exact timing for a meeting on Monday or Tuesday. The outside breaker was left in the Off position upon departure. Customer would also like pricing on a duct cleaning for all 3 systems.
