Planned inspections and service intended to reduce failures, hazards, and larger repair costs.
What preventive maintenance means in practice
Preventive work is scheduled by time, season, usage, or equipment guidance rather than waiting for a breakdown. Records should show the asset, due date, work completed, result, and next interval.
Example
The owner schedules HVAC service and smoke-alarm checks before peak season and records the results by unit.
