Start with operational risk

Identify what happens if the system underperforms or stops. A meeting room, server-adjacent space, treatment room, hotel bedroom and retail floor carry different comfort, continuity and access consequences.

The plan should reflect equipment quantity, operating hours, environment, redundancy, occupancy, warranty conditions, seasonal peaks and how quickly the business needs information or support when a defect appears.

Useful maintenance brief

List sites, assets, critical rooms, operating hours, access rules, current faults, service history, reporting needs and the business impact of failure.

Define what each visit includes

Service is too vague on its own. The agreed scope should identify which assets are covered, what inspections, cleaning and functional checks are performed, how findings are recorded and which activities or materials are excluded.

Depending on the equipment and approved method, work may address filters, coils, drains, fans, controls, temperatures, operating behaviour, visible refrigerant or electrical concerns, outdoor-unit condition and access. Technical activities must be completed by appropriately qualified personnel.

The live maintenance offer should be reviewed against manufacturer guidance, applicable duties and the company’s approved procedures before publication.

Set frequency by use and risk

Lightly used office equipment may not need the same visit pattern as systems operating long hours in hospitality, healthcare, retail or specialist environments. Dirty, greasy, dusty or coastal conditions can also change the maintenance need.

Visit frequency should consider manufacturer requirements, warranty, asset condition, operational criticality, system type and previous defects. Seasonal planning can help identify issues before peak demand.

Good records make maintenance more valuable

Each visit should leave a usable record of the assets attended, work completed, measurements or observations, defects, photographs where useful, priority and recommended next action.

Across several sites, consistent asset naming and report structure allow facilities teams to compare condition, recurring faults, repair cost and replacement need. A pile of unstructured reports does not create an estate view.

  • Unique asset or location reference
  • Manufacturer, model and serial details where available
  • Visit date, engineer and work completed
  • Condition, defect and priority
  • Photographic or measurement evidence where relevant
  • Quotation or decision route with an accountable owner

Separate urgent faults from planned improvements

Not every observation carries the same risk. Reports should distinguish immediate safety or operational concerns, defects likely to cause failure, performance issues, housekeeping items and longer-term improvement opportunities.

The customer also needs a clear process after the report: who reviews findings, how quotations are approved, what response commitments apply and how access or parts delays are communicated.

Use evidence to plan repair and replacement

Age alone does not decide replacement. Consider condition, parts availability, refrigerant, failure history, repair cost, efficiency, capacity, controls, building changes and the consequence of another failure.

A planned replacement can be phased around budgets and operations, while a reactive failure may force a compromised choice. Maintenance data should help identify that decision early enough to act deliberately.

Questions for a maintenance proposal

  1. Which sites and assets are included, and how will the register be maintained?
  2. What exactly is completed at each visit?
  3. How was visit frequency selected?
  4. Which qualifications, supervision and working procedures apply?
  5. What report format, priorities and evidence will be provided?
  6. What response model, attendance charges and operating hours apply?
  7. How are quotations, parts, specialist access and subcontracted work handled?
  8. What is excluded, and which assumptions affect the price?
  9. How will recurring defects and replacement opportunities be reviewed?
  10. Who owns communication at site and account level?
