Arrived onsite for heating maintenance 1 gas fired furnace. Turn heat on and confirmed operation. Brushed and Wiped down furnace blower cabinet and gas burners. Burners fired and are in good working order. Observed noise from combustion exhaust system. Measured 1.3 amps which is within specification but motor has used over 90% of its life. No visual impingement detected. Checked electrical. Measured .9 amps on the hot surface ignitor. Measured 63 degree heat rise. Cleaned the flame sensor. System is operating as it should. Due age and condition of furnace, recommend updating the system. Homeowner noted only the indoor coil is new; the outdoor AC condenser is older and due for replacement as well.
