The most-complained-about asset in any commercial building, and the one living in the harshest environment. Nearly every rooftop failure traces back to airflow, refrigerant charge, or controls — and all three drift gradually rather than breaking outright.
ChatterFix builds these as child assets under rooftop hvac unit, so failure history and PM completions attach to the component that actually failed — not just to the machine.
The failure modes worth designing a maintenance schedule around — in rough order of what they cost when they happen.
Recording that a PM was "done" tells you nothing next quarter. These are the readings that let you see a failure coming — and the reason ChatterFix captures measurements against the asset rather than just completions.
The parts whose absence turns a short repair into a long outage.
The PMs ChatterFix schedules against this equipment, with intervals and time estimates.
