Make a decision
Annual inspection versus tune-up
One scope
Inspection documents safety, venting, controls and operating condition appropriate to the fuel appliance.
The other scope
A tune-up may add specified adjustments, cleaning or measurements, but the label varies by contractor.
A concrete example
One invoice may say 'tune-up' but list only filter and thermostat checks. Another may say 'inspection' and document venting, combustion and safety findings. Compare the actual checklist.
Which question settles it?
Request a written checklist of tasks and measured findings instead of comparing service names.
