Arrived on site to perform maintenance on 18 year old Rheem heat pump. Cycled system for heat. Checked systems electrical and components. Temperature split is in range, refrigerant levels in range however System is operating on r-22 refrigerant that has been phased out. Indoor blower motor has leaked out a significant amount of oil and amp draws are fairly high and inefficient. Primary motor control has some burning and pitting on contact points. Comrpessor amp draws are also high and condenser fan motor is leaking oil as well. Performed coil clean. Blower wheel is slightly dirty. Replaced 1 inch filter. Ducting is in very poor condition. Attic has enough space for a possible relocate in the future. Went over findings and recommendations with homeowner. She is fully aware of the condition of the system and is aware that she will have to replace in the future. She has gotten quotes in the future And have an idea on what a project like that would consist of. Offered to have someone come
