Imagine an office comparing annual HVAC offers solely by the number of visits. One lists “cleaning”; another specifies asset-linked checks and reports. The visit counts match, but the deliverables do not. This is an illustrative comparison.
A useful agreement begins with the installed equipment and its condition. Split units, packaged equipment and central systems need scopes appropriate to their actual configuration.
Compare the content and outcomes of the service before comparing its visit count.
Start with the equipment register
Record equipment types, locations, identifiers, available technical information and access constraints. Clarify which associated controls, pumps, ducts or drains are included.
Agree how incomplete inventory information and pre-existing defects will be handled before final scope approval. Routine maintenance and rehabilitation of an already faulty system are different requirements.
Define the work within a visit
Request tasks aligned with the relevant equipment guidance, including appropriate inspection, cleaning, checks and post-work verification. “Cleaning” does not automatically include full component dismantling or deep cleaning.
Task frequency should reflect manufacturer guidance and operating conditions. DOE’s equipment resources frame maintenance as a planned equipment-specific programme, rather than a uniform wash for every system.
Separate calls, labour and parts
State coverage hours and the reporting channel, then clarify diagnosis, repair labour and spare-parts coverage. An included call-out does not necessarily include every subsequent action.
Do not treat refrigerant top-up as a routine requirement for every unit. Need should follow diagnosis and manufacturer guidance. Clarify whether finding and repairing the cause of refrigerant loss is included and how additional supply is approved.
Keep a history for each asset
Ask reports to connect symptoms, actions, findings and unresolved work to the equipment identifier. A closed ticket should communicate the service outcome, rather than merely confirm attendance.
For a NACE enquiry, provide the inventory, operating hours, access information and recurring issues. Compare proposed tasks, service boundaries and approval arrangements before comparing visit totals and price.
Price equipment groups and starting conditions separately
Grouping similar equipment can make an annual AC maintenance quotation easier to review without hiding differences. Organise the schedule by system, location and access requirements while retaining an individual identifier for every unit. The combined equipment count alone is not a sufficient comparison basis.
| Equipment group or condition | Required pricing detail |
|---|---|
| Similar, accessible units | Quantity, recurring tasks and each task’s frequency |
| Units requiring special access | Access requirements, responsible party and any associated cost |
| Units already faulty at survey | Diagnosis or repairs required before the agreed programme starts |
| Shared associated components | Agreed coverage of controls, ducts or drainage |
Ask the schedule to distinguish attending the site from servicing each unit, including how incomplete tasks will be recorded. If only some equipment is covered, show the remainder as excluded or awaiting a separate proposal. This supports discussion of annual cost and future additions without assuming a fixed visit count or cleaning work that the quotation does not include.
Questions & acceptance checklist
- Confirm included equipment.
- Define tasks and cleaning depth.
- Separate calls from planned visits.
- Clarify labour, parts and refrigerant.
- Require asset-linked records.
Before you decide
Does an annual contract include regular refrigerant top-ups?
Do not assume so. Need follows diagnosis, and the scope must identify any leak work and refrigerant supply.
Are more visits always better?
Task suitability, execution and follow-up matter alongside frequency.
Is response time the repair deadline?
No. Acknowledgement, attendance, diagnosis and restoration need separate definitions.
Define your maintenance contract scope
Share the site type, asset list and operating hours. Visits, reports, exclusions and response arrangements are agreed in the quotation.
