Preventive maintenance
Routine upkeep and documented follow-up intended to reduce avoidable wear and catch visible changes early.
Full definition
Preventive maintenance combines visual observations, reminders and appropriate hands-on upkeep. Examples include adjustments, caulking and small fixes before they become bigger maintenance concerns.
Essential provides quarterly visits and a maintenance hour each quarter; Pro provides monthly visits and a maintenance hour each month. Maintenance cannot guarantee that breakdowns or hidden issues will never occur.
Why does this matter?
A repeatable care routine is different from waiting for something to break.
