Preventive Maintenance: The Complete Guide for Facilities

Preventive maintenance (PM) is scheduled maintenance performed regularly — before failure happens — to keep equipment and facilities in sound working condition. Its opposite is corrective (reactive) maintenance: waiting until something breaks, then fixing it. The difference isn't just technical, it's financial: an unplanned breakdown typically costs several times a scheduled service, on top of downtime, unhappy occupants and contractual penalties.

Why preventive maintenance deserves priority

• Longer asset life: an AC unit cleaned and inspected regularly lasts years longer.
• Fewer surprise breakdowns and less downtime at peak hours.
• Lower total cost: emergency repair is more expensive than scheduled inspection.
• Contract compliance: most O&M contracts require documented PM programs.
• Safety: catching electrical, fire and elevator risks before they become incidents.

How to build a PM schedule (5 steps)

1. Inventory your assets: register every important piece of equipment (HVAC, elevators, pumps, generators, fire systems) with its location.
2. Set a frequency per asset: from manufacturer recommendations and real usage — weekly, monthly, quarterly, yearly.
3. Write a checklist per task: clear steps the technician follows and documents with photos.
4. Assign ownership: every schedule has a responsible technician or contractor, and the system sends them the task automatically when due.
5. Measure and improve: track on-time completion and repeat failures, and adjust schedules based on data.

Common schedule examples

• Central HVAC: monthly filter cleaning, quarterly full inspection.
• Elevators: monthly preventive inspection (often contractually mandatory).
• Water and fire pumps: weekly-to-monthly operational checks.
• Backup generators: monthly test runs and periodic oil checks.
• Alarm and safety systems: documented quarterly inspection.

Why PM programs fail on paper and Excel

A schedule that lives in a spreadsheet depends on someone remembering to open the file, send out tasks, chase technicians, then document results. One busy week and the whole program collapses. A digital system flips this: scheduling is automatic, and the task reaches the technician on time as a WhatsApp message with a link that opens instantly — they run the checklist, attach photos and close it, in whatever language they write, Arabic, Urdu or anything else, with no app to install and no training. Management sees completion rates live.

KPIs to track

• PM Compliance — on-time completion rate; aim for 90%+.
• Preventive-to-corrective ratio — the higher it is, the fewer surprise breakdowns.
• Mean Time Between Failures (MTBF) per asset.
• Repeat failures on the same asset — a signal to replace it or raise its PM frequency.

Frequently asked questions

What is preventive maintenance?

Scheduled maintenance performed regularly before failure — inspection, cleaning, calibration and part replacement — to preserve equipment and reduce surprise breakdowns.

What is the difference between preventive and corrective maintenance?

Preventive is scheduled before failure; corrective is repair after it happens. Relying only on corrective maintenance raises costs and downtime.

How often should AC units get preventive maintenance?

Commonly monthly filter cleaning and a quarterly full inspection, with higher frequency in dusty climates or heavy usage such as Saudi Arabia.

What is PM Compliance?

The percentage of preventive tasks completed on time out of all scheduled. A healthy rate is typically 90%+; a drop is an early warning of coming breakdowns.

How do I run PM without burdening technicians?

Use a system that sends each task on time as a WhatsApp message with a no-login link — as MRFQ does — so the technician runs the checklist and attaches photos in their own language, no training needed.
