Blue shield club heater maintenance. Joe(JC)R. 12/23/2024 Performed full system evaluation and safety inspection. I arrived to perform the customer’s annual heater maintenance. The customer said that everything was running well and didn’t have any questions. I then inspected the package unit. The heat exchanger was in good shape and the heater components were in good shape. The system is operating correctly at this time. I also replaced the filter.
