Split systems concentrate their failure risk in joints made on site rather than in the factory, which is why the flare connections deserve more attention than the equipment itself. The other half of the story is condensate: a blocked drain on a wall-mounted head puts water into an occupied room, so it becomes a customer problem long before it becomes a maintenance one.
ChatterFix builds these as child assets under ductless split system, 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.
