I am a professional home service technician who recently completed a furnace maintenance job. The furnace was inspected and tested to ensure it was operating at peak efficiency. The technician cleaned the carbon buildup on the flame sensor to improve its performance. They also checked the amp draw of the blower and inducer motor to ensure they were operating within acceptable parameters. The technician also replaced the air filter and inspected the electrical connections to ensure they were secure. Finally, they provided the customer with a detailed report of the maintenance performed and answered any questions they may have had.
