Filters are the cheapest maintenance in the building and the most consequential when skipped. A loaded filter starves airflow, which drops capacity, ices coils, and drives fan energy up — and once media blows out or bypasses a bad seal, dirt loads the coil instead, which is a far more expensive clean.
The steps ChatterFix schedules for this PM. Every step is a checkable item on the work order — a technician can speak their way through it without touching a keyboard.

Comfort complaints nobody can explain, coils that need chemical cleaning years early, and a fan running harder than it should for the entire period between changes.
Quarterly suits most commercial buildings. Let differential pressure set the real interval — record it at every change and you will quickly learn which units need more frequent attention and which are being changed too early.
This procedure — and every other PM for your industry — is already built into ChatterFix. Pick your industry and it lands on the right equipment, on the right interval, in about three minutes.
