Performed heating maintenance on attic 80% gas Lennox furnace. Changed filter. Checked capacitor for indoor blower motor and found it to be low, after customer approval I replaced capacitor to bring system to its most efficient state and to prevent blower motor from going out. Checked amperages on indoor blower motor and inducer draft motor. Checked voltage and burners. Checked pressure switch, flame sensor, and other safeties. Checked temperature split and thermostat functionality. System heating and operational at this time. Serviced customer near Forest Ave in Chico, CA.
