Blue shield club heating maintenance. Joe(JC)Ritchal 12/14/2023 Performed full system evaluation and safety inspection. Arrived to perform a customers annual fall service. The customer didn’t have any questions for me so I went ahead and started with the maintenance. I checked the heat exchanger and safeties and then checked the blower and heating components. I also cleaned the flame sensor and performed a carbon monoxide test and change the filters for the customer. Is operating correctly at this time.
