2003 Carrier furnace running in good condition despite age. 16x25x1 air filter is new today. Clean flame sensor and check ignitor. Blow out furnace to remove loose dust and dirt. B-vent is in good condition and no sign of leaks. 0PPM CO detected during testing. Run test unit in heating mode. Delta t is within spec. Blower motor and inducer motor running within spec. Furnace is operating properly, efficiently and ready for Winter. Recommended to put up curtains or install a thermostat with remote sensor as the room the thermostat is in gets direct sunlight in the morning. This will cause the system to over cool and under heat the rest of the house.
