Annual furnace inspection
Annual fuel-appliance inspection addresses safe function, while a cleaning quote may cover only selected dirty surfaces.
What to observe
Ask for a checklist naming combustion, venting, controls, drainage and airflow items appropriate to the model.
A field example
A receipt reading 'duct cleaning' may document no burner, vent or control checks. Request the inspection checklist and technician identity so next winter's records distinguish fuel safety from air-path cleaning.
What the written work should say
Book a TSSA-registered contractor for fuel work and retain the findings and any measured results in a service record.
Where this task stops
Do not treat a duct-cleaning receipt as proof of an annual furnace safety inspection.
