Preventive Maintenance Standard
Cadence, scope and evidence for keeping Smart Citizens systems healthy for the long term.
The essentials
- Monthly, quarterly and annual routines defined
- Every visit produces a signed maintenance report
- Owner receives a plain-language health digest
- AMC customers get scheduled visits by default
Purpose
Prevent silent failures and extend the useful life of the installed system.
Scope
All Smart Citizens residential and commercial systems under an active support contract.
Design principles
Principle 1
Predictable — a fixed calendar per plan
Principle 2
Evidenced — every visit closes with a signed report
Principle 3
Owner-visible — the owner sees a plain-language health summary
Principle 4
Data-driven — use portal telemetry to prioritise

Frequently asked questions
Frequently asked questions
Is remote maintenance enough?
For simple systems yes; for premium villas, quarterly on-site inspections catch physical issues telemetry cannot.
Can we opt out?
Yes, but out-of-contract issues fall under time-and-materials.
