Upon receiving the service request, I promptly dispatched Douglas to address the furnace issue. Upon arrival, Douglas diagnosed the problem as a faulty igniter. He carefully removed the old igniter and installed a new one, ensuring all connections were secure and the furnace was functioning optimally. Throughout the process, Douglas took care to explain each step to the customer, ensuring they understood the repair. Once the replacement was complete, Douglas tested the furnace to confirm it was working correctly. The customer was satisfied with the repair, and payment was collected upon completion.
