In Sun City, near West Ocotillo Drive and North 102nd Drive performing Fall preventative maintenance on a Goodman package heat pump. Completed maintenance service in accordance with maintenance checklist. Recommend upgrading system due to age and the use of R22. Condensing fan motor is high amping at time of service. Fixed broken drain line. Also, the transformer by thermostat is going out; recommend having a handy man out to replace it.
