Arrived on site and checked in with homeowner for regular maintenance on heat pump package unit on roof. Went to roof and removed power. Inspected wiring harness, motors, and capacitors. Jumped system into cooling mode. Recorded amp draws, refrigerant pressures and temp splits. Found electronic air cleaner in return duct. Removed all media and rinsed out with water resetting gauge to show its clean. No issues to be noted with this equipment. System is performing to manufacture specifications at this time. Recommend adding ac Renew to refrigeration circuit to aid with oil return and condition existing oil due to age of 9 years. Will provide estimate. Customer approved quote for ac renew addictive after explaining product. Went to roof and injected through suction line using high pressure side to move oil into system. Slowly flowed into system over course of about 5 mins and retested system health. Compressor amp draw lowered and pressures look normal. All work is complete.
