A rooftop unit spends its life outdoors, and everything that matters about it degrades from exposure: coils foul, belts stretch, dampers seize, and refrigerant slowly escapes. The seasonal changeover is where you find all of that at once, before the first genuinely hot or cold week makes it everyone's problem.
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.

The seasonal changeover is where you find all of that at once, before the first genuinely hot or cold week makes it everyone's problem.
You discover the failure on the first 35°C day, along with every other building in the city — which is exactly when contractor response times are worst and refrigerant is most expensive. Fouled coils also raise energy cost quietly all season, which nobody attributes to maintenance.
Twice a year, ahead of the cooling and heating seasons rather than during them. In dusty or coastal locations, add a mid-season coil inspection — salt and grit foul condensers far faster than the calendar suggests.
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.
