On-board HVAC/CVC inspection & audit
Marine HVAC audit
on yacht
Suspecting a performance drop, humidity issues, intermittent failures, or planning a refit or pre-purchase survey? We carry out HVAC audits on board — findings, measurements, root cause analysis and an actionable report.
Why carry out an HVAC audit on a yacht?
Secure reliability, improve onboard comfort and make informed decisions based on findings and measurements — pre-purchase, refit, insurance.
Reliability & onboard comfort
- Unstable temperatures, hard-to-maintain zones, discomfort in cabins or saloon.
- High humidity, odours, condensation, mould, accelerated corrosion.
- Recurring failures (compressor, pumps, valves, sensors, automation).
Costs, energy & planning
- Overconsumption caused by fouling, hydraulic imbalance or poor settings.
- Reduced risk of in-season breakdown, better refit planning.
- Action prioritisation (quick wins vs. major works).
Pre-purchase / refit / insurance — decide with facts
The audit provides a factual basis for a pre-purchase, a refit, negotiations with a yard or subcontractors, or discussions with an insurer. Where the context is sensitive, the process can be structured to improve traceability — timestamped photos, logs, measurement records, appendices.
What the inspection covers
Typical scope — confirmed after a quick briefing (vessel, symptoms, objectives, available window).
- Chiller(s), condensers/evaporators, refrigeration units.
- AHUs / air handling units, terminal units, fan coils.
- Chilled/hot water circuits: pumps, valves, balancing, filters.
- Ductwork: losses, leaks, insulation, noise, dampers, registers.
- BMS/automation: control logic, alarms, data logs, setpoints.
- Anti-condensation strategies / humidity control (where present).
- Maintenance: frequency, parts, recurring issues, drift.
- Available documentation (as-built drawings, schematics, logs, history).
- Temperature / relative humidity / dew point per zone.
- ΔT, pressures, airflow / water flow rates where instrumentation allows.
- Operating records (cycles, instabilities, overloads).
- Air quality: indirect indicators (ventilation, air changes, filtration) as required.
Exact scope confirmed after a quick briefing (vessel, symptoms, objectives, intervention window).
Audit methodology — neutral, structured, actionable
Briefing → on-board visit → root cause analysis → prioritised action plan.
Briefing
Objectives, symptoms, zones, access, operational constraints, existing documentation.
On-board visit
Visual inspection, measurements, basic tests, factual evidence collection — timestamped photos, measurement logs.
Analysis & root causes
Hydraulics, aeraulics, controls, fouling, sizing, usage — identification of underlying causes.
Prioritised recommendations
- Immediate actions (adjustments, targeted maintenance, balancing).
- Corrective actions (replacements, humidity control improvement, partial redesign).
- Prioritisation: safety / comfort / energy / reliability / costs / lead times.
- FR/EN deliverable and technical liaison with yard / integrator on request.
Deliverables — actionable report within 48h
Structured to be usable by your team, insurers, lawyers or in legal proceedings.
- Executive summary (risks, priority actions).
- Findings by zone / equipment with timestamped photos.
- Measurements, test conditions, interpretation.
- Hypotheses on root causes and validations.
- Prioritised action plan (short / medium / long term).
- Inspection checklist and document matrix.
- Maintenance / drift / alarm tracking table.
- Refit recommendations (specifications, yard items).
- Traceability note (for legal or insurance context).
