Maintenance is a specialist job: the person who opens cabinets on purpose before the season does it for you.
Tune-ups only work if the same checklist is followed and the numbers are written down. The maintenance specialist runs fall furnace and spring AC visits and flags the ignitor that will not survive January.
They also set reminder cadence so you are not relying on memory when October hits.
Catch the small worn part before it is a Saturday night. If you book this kind of work, this is the seat on the truck that is accountable for it.
