Short answer: build five connected AC files
A useful Cayman AC review connects system identity, documentary history, observed operation, responsibility, and electricity evidence. Keep confirmed facts, observations, assumptions, and professional conclusions separate. This checklist is not an HVAC inspection, efficiency rating, load or sizing calculation, electrical assessment, code decision, remaining-life estimate, repair prescription, electricity quote, provider endorsement, condition waiver, or transaction recommendation.
- Map each condenser, indoor unit, ducted system, split system, thermostat, controller, and room or zone to the exact address and unit.
- Request dated installation, approval, warranty, service, repair, and unresolved-recommendation records where they exist.
- Observe each zone under recorded conditions without diagnosing performance, efficiency, moisture, or cause.
- Separate owner, landlord, strata, manager, tenant, and contractor authority before anyone promises access, work, payment, or handover.
- Use complete redacted CUC statements as whole-property evidence—not as an AC submeter or a promise of the next household's bill.
Define the exact system and every control zone
Do not compare homes using listing phrases such as central air, split AC, recently serviced, or energy efficient. Build an equipment register tied to the exact property and note which rooms, common areas, and outdoor components each item serves. If a label, component, or area is inaccessible, record the gap instead of guessing.
| Register field | Evidence to capture | Decision question |
|---|---|---|
| Property and access | Address, unit, strata/building, occupied or vacant state, viewing time, access owner, locked areas, and keys or controls supplied. | Did the review cover the exact home and every accessible zone? |
| Equipment identity | Location, make, model, serial, capacity label, documented installation date, outdoor/indoor pairing, and photos. | Can each record and observation be matched to the right component? |
| Controls and zones | Thermostat/controller identity, room or area served, schedule access, remote/app access, displayed errors, and handover owner. | Who can operate or reset each zone at signing and handover? |
| Shared interfaces | Common condensers, ducts, drains, plant rooms, roof/balcony access, strata restrictions, and service-entry arrangements. | Which elements are private, shared, inaccessible, or controlled by another party? |
Build the installation, approval, warranty, and service timeline
Create one chronology rather than accepting a folder of unrelated invoices. Match every document to the equipment register and preserve gaps. Planning's Building Control Unit handles permits, inspections, and final certificates, while its published development-process material includes mechanical drawing review and mechanical inspection stages. The process document is dated 2019, so ask Planning which current record or process applies to the exact work; do not infer that every service visit or replacement required a particular approval.
| Timeline item | Evidence | Boundary |
|---|---|---|
| Installation or alteration | Proposal, invoice, approved drawings where applicable, equipment labels, permit/inspection/completion records, and handover date. | A record does not prove present condition or that later changes match it. |
| Warranty | Issuer, equipment covered, start/end dates, registration, exclusions, transfer rules, proof of purchase, and claim contact. | Do not promise transferability or acceptance without current confirmation. |
| Routine service | Dated visits, equipment serviced, scope, findings, filters/parts, recommendations, invoice, and next owner. | A service invoice is not a condition report, efficiency result, or life estimate. |
| Repair or unresolved work | Observed issue, diagnostic/reporting scope, quote, approval, completed work, follow-up evidence, and open recommendation. | Keep a contractor's finding within its stated scope and date. |
Use the viewing as an observation record—not an inspection
Record the conditions under which each zone was viewed: time, occupancy, doors and windows, control setting and display, outdoor conditions, and how long the system was observed. Note control response, airflow differences, unusual sound or vibration, odour, visible water or staining, corrosion, damaged insulation, blocked access, error displays, and inaccessible components. Do not diagnose cause, capacity, efficiency, moisture or mould, indoor-air quality, electrical safety, refrigerant condition, or repair need from a viewing.
- Photograph the control display before and after the observation without changing protected settings or opening equipment.
- Record which rooms were checked and which were locked, occupied, furnished, recently opened, or otherwise limited.
- Describe what was seen, heard, felt, displayed, or inaccessible; avoid labels such as failing, undersized, mouldy, unsafe, efficient, or fully operational unless a qualified report supports the exact claim.
- Escalate unexplained water, staining, odour, repeated errors, material comfort differences, unusual sound, missing records, or inaccessible equipment into a bounded professional question.
Define a bounded HVAC specialist scope
A general inspector, document review, or viewing may identify a gap without answering it. Give the HVAC specialist the equipment register, observations, history, access constraints, transaction deadline, and the exact requested scope. Ask the specialist to state what was inspected or tested, what was inaccessible, findings and limitations, options or follow-up within professional scope, and what evidence would close the question. This page does not select a contractor, order work, diagnose equipment, specify repair, or waive a condition.
| Brief element | Write it down | Avoid |
|---|---|---|
| Question | The exact record gap, symptom or observation, component, zone, and decision it affects. | A vague request to check the AC. |
| Access and authority | Who grants entry, opens plant/roof areas, operates controls, supplies records, and may authorize testing or work. | Assuming a tenant, agent, or technician can approve every step. |
| Scope and limitations | Equipment included, methods, exclusions, inaccessible items, deliverable, and whether further professional review is recommended. | Treating a quote, tune-up, or visual visit as a full condition or compliance assessment. |
| Deadline and closure | Report date, response owner, quote/repair path if requested, completion evidence, recheck question, and principal decision deadline. | Letting an open recommendation drift past signing or handover. |
Compare complete electricity evidence without promising a bill
CUC measures electricity usage at the property meter and bills through base and pass-through components. Ask for complete redacted statements for as many comparable periods as are available, then record billing period, metered usage, occupancy, material loads, outages, solar contribution where relevant, and equipment changes. A statement is whole-property evidence: it does not isolate AC consumption, identify the person who used the energy, value the property, or predict another household's future bill.
- Compare metered usage as well as the billed total; components and rates can change over time.
- Preserve the full billing period and reading context rather than screenshots of one bottom-line number.
- Record occupancy, work-from-home days, guests, vacancies, thermostat practices, pool or pump loads, laundry, solar, outages, and equipment changes when known.
- Label missing bills, estimated context, redactions, and non-comparable periods clearly instead of filling gaps with averages.
Normalize evidence before comparing two homes
Move to Cayman recommends a practical evidence normalization—not an energy audit or CUC formula. Put statements from two properties on the same comparison sheet and note why periods may differ. Weather, occupancy, floor area, shading, window and door use, setpoints, dehumidification, pool or pump loads, solar, outages, equipment changes, and household behaviour can all affect the result. Use the comparison to frame questions, not to calculate savings or declare one system more efficient.
| Comparison field | Property A | Property B |
|---|---|---|
| Billing evidence | Complete periods, usage, components, gaps | Complete periods, usage, components, gaps |
| Occupancy | People, vacancy, guests, daytime use | People, vacancy, guests, daytime use |
| Property context | Floor area, zones, shading, doors/windows | Floor area, zones, shading, doors/windows |
| Other material loads | Pool/pumps, laundry, hot water, EV, solar | Pool/pumps, laundry, hot water, EV, solar |
| System changes | Installation, repair, outage, schedule changes | Installation, repair, outage, schedule changes |
Route replacement, import, and supply questions correctly
CUC publishes standard power-supply information and directs customers to contact it during project planning. When replacement, imported equipment, electrical changes, or service configuration is material, record the exact equipment and property question and route it to CUC, Planning, and appropriately qualified professionals as relevant. Do not perform a compatibility analysis, specify equipment, declare the property's supply, approve work, or infer that a service upgrade is required.
- Capture the exact model, labels, proposal, location, existing supply information, and proposed work before asking a compatibility or approval question.
- Ask Planning which current permit, inspection, drawing, or completion route applies rather than relying on an old invoice or a general process document.
- Ask CUC and qualified electrical/HVAC professionals about the exact property's supply and proposed equipment instead of generalizing from standard specifications.
- Keep technical, commercial, landlord/strata, insurance, and transaction approvals separate; one does not automatically establish the others.
Turn repair or replacement promises into written conditions
A verbal promise that AC will be serviced, fixed, credited, replaced, or handled after closing is not a closure record. State the exact component and zone, requested outcome, authorized scope, access owner, approval path, cost owner, deadline, report or invoice required, completion evidence, recheck question, extension route, and what the principal will decide if the item remains open. Obtain appropriate legal, lender, insurance, and technical advice for the exact transaction.
- Separate diagnosis, quote, authorization, completed work, payment, warranty, and verification; they are different stages.
- State whether an allowance or credit is provisional, what it excludes, who carries overruns, and whether it changes any other condition.
- Do not let a seller, landlord, agent, inspector, contractor, or this guide make the buyer's or tenant's proceed/stop decision.
- Retain the final report, invoice, photographs, warranty, control handover, and written acceptance with the property file.
Plan continuity for outages, storms, vacancy, and household needs
Cooling continuity can matter during outages, storms, vacancy, remote work, pet care, or for older residents and people with medical temperature needs. Record who receives official alerts, who can access the property, which controls can be used after an outage, how occupants will communicate, what backup location or support route exists, and who decides when to leave or seek care. This is a continuity file—not a medical, resilience, generator, or storm-performance guarantee.
- Follow current HMCI, CUC, healthcare, landlord, strata, and building-management instructions for the actual event.
- Record pets, children, older residents, medication or equipment needs, remote-work deadlines, and trusted local contacts without publishing private details in shared files.
- Confirm vacancy checks, condensate or leak escalation, restart authority, alarm access, contractor access, and post-outage observations in writing.
- Keep a fallback location and transport/contact plan that does not depend on one building, one phone, or one cooling system.
Use a handover register for controls, records, and open work
At closing or move-in, reconcile the equipment register with the installed property and transfer every control, key, remote, app/account access route, manual, warranty, service contact, maintenance record, filter/service note, approval record, open quote, promised remedy, invoice, and completion record. Note what was not supplied and who owns the follow-up. Do not accept a generic keys handed over note as proof that the AC file is complete.
| Handover item | Evidence received | Open owner and deadline |
|---|---|---|
| Equipment and zones | Register, labels/photos, location/access, controls, manuals | Missing identity, inaccessible zone, or control owner |
| History | Approvals where relevant, installation, warranty, service, repair, recommendations | Record custodian or current official/professional check |
| Operation | Observed-condition log, specialist report, limitations, open work | Report, quote, authorization, completion, or recheck owner |
| Commercial and responsibility | Lease/title/strata terms, service contract, invoices, budget or allowance | Legal, owner, landlord, strata, insurer, lender, or principal decision |
| Continuity | Emergency contacts, access, alert/restart route, vacancy plan | Building/household owner and next review date |
Close with an explicit property decision log
Summarize confirmed equipment identity, records received, observed conditions, electricity evidence, responsibility, specialist findings, written conditions, and unresolved gaps. Then record one explicit next action for the named principal: proceed on the evidence available, obtain a bounded specialist or professional review, keep a written condition open, seek an extension, or stop. Move to Cayman can help organize an exact-property evidence plan and introductions, but it does not determine condition, compliance, responsibility, price, repair, suitability, or whether anyone should transact.
- Keep fact, source, date, property/unit, author, limitation, and follow-up owner beside every material entry.
- Distinguish not supplied from does not exist, not accessible, not applicable, and not yet verified.
- Record the decision-maker, advice obtained, deadline, extension route, and the evidence that closed—or failed to close—each condition.
- Archive a redacted working copy for the household and a controlled full copy for the parties who are entitled to it.
