Arrived on site to perform AC diagnostic on 2004 system. Upon arrival clients son is in town and will be handling appointment for her. He stated that just last night the unit started blowing hot air and was not cooling down. Maintenance has not been done since 2020 and in 2013 the fuse was replaced. Began diagnostic at outdoor unit and immediately found that 30 amp fuse was blown. Inspected electrical components and found that duel secondary motor control is weak on hermetic side terminal. Condenser fan motor is also over amping. System contains R22 which is no longer manufactured as of 2020. Pressures are in range at this time. At this time Ruth’s son would like to go through with the mandatory repair and sign up on a maintenance plan to keep both AC and heater at standard twice a year. Clients are not in a position to go over replacement options and understand that system is past design life at this point. Installed components and system is operational and cooling upon departure
