Ask whether the quoted price includes a full cleaning, combustion analysis, and safety device testing — or just a visual inspection.
For oil systems especially, nozzles and filters should be replaced, not just cleaned — confirm this is standard practice.
A thorough technician should be able to provide actual combustion analyzer readings, not just a verbal "it's running fine."

Many providers offer annual contracts that bundle cleaning with priority emergency service — often worth it for older systems.
