Performed preventative maintenance on hvac system for customer. Discussed with customer about maintenance needed and if filters needed to be changed. Customer takes care of the filters. I inspected the blower assembly, motor, electrical components, burners, flame sensor, ignitor, gas valve, inducer motor, evaporator coil, heat exchanger and overall system condition. Cleaned flame sensor and dust off the components. Checked thermostat operation, amps, temperatures and pressures. Inducer motor is vibrating and the amps are at max. Recommended replacing the inducer motor. Customer would like me to get pricing and availability of the part. Overall system is operating properly.
