Why refrigerant traceability is becoming unavoidable in 2026
What the log book brings on site: evidence, history, transparency
In 2026, with stricter F-Gas rules and more concrete inspections, the log book becomes your best ally. It tracks the type of refrigerant, quantities added or recovered, the date, the technician, and the container reference. You have clear evidence, and a useful history for diagnosing faster.
The risks of skipping it: inspections, client disputes, wasted time
Without an up-to-date log book, an inspection can quickly turn into a paper chase. You risk return visits, endless back-and-forth, and a real risk of dispute if a leak or breakdown occurs and nothing is dated. In the end, it's wasted time and often lost margin.
Which interventions are covered: installation, maintenance, repair, refrigerant recovery
As soon as the circuit is opened, you log it. Installation and commissioning, topping up the charge, tightness checks, maintenance, repairs, and end-of-life refrigerant recovery. Good practice: enter the information the same day, before leaving the property.
Obligation
Leak checks: is this job covered?
The obligation is not triggered by the kilograms of refrigerant but by tonnes of CO₂ equivalent: the charge times the fluid’s global warming potential. Hence different answers for the same charge depending on the fluid.
3.0 kg
Equivalent charge
2.0 t CO₂e
GWP 675
Leak check
Not required
Trigger threshold
5 t CO₂e
that is 7.4 kg of this fluid
Below the threshold: no periodic check
This is the usual case for a residential R32 multi-split. What still applies: the company’s certification, the tightness test and evacuation at commissioning, the intervention record and the logbook.
Regulation (EU) 2024/573, article 5. Periodic checks are one thing; the company’s certification, the tightness test at commissioning and the record keeping apply whatever the charge.

How to keep a clear, compliant refrigerant log book
Information to record at each intervention: refrigerant type, quantities, equipment
At each visit, record the date, location, equipment ID, refrigerant type (e.g. R32, R410A) and the quantities added, recovered or transferred. Also note the reason (commissioning, maintenance, leak), the tightness check result and the destination of the recovered refrigerant. One line per piece of equipment limits omissions.
Who enters what: technician, team lead, admin staff
The technician records the measurements and actions carried out on site. The team lead checks consistency (units, signatures, equipment numbers) and settles any discrepancy. Admin staff centralise, file and prepare supporting documents. Goal: zero grey area.
Paper or digital format: choose based on how your site is organised
Paper remains practical for quick repairs, provided it's legible and archived. Digital makes history, photos, export and inspections easier, especially when several teams are involved. Choose a single format, accessible offline, then set an archiving rule common to everyone.
What entries guarantee solid refrigerant traceability
Identifying the equipment: location, tagging, serial number
Note the site address, the area of the property, and the unit tagging. Record the brand, model, serial number, and, if possible, the commissioning year. Add the refrigerant type (e.g. R32) and the nominal charge shown on the nameplate. The goal is to find the equipment again without error.
Tracking refrigerant movements: charge, top-up, recovery, transfer
At each intervention, record the date, the technician, the refrigerant type, and the quantities (in kg) added or removed. Distinguish between initial charge, top-up, recovery, and transfer to a cylinder. Specify the origin of the refrigerant (new, reclaimed) and its destination (reuse on site, return to the recycling chain). Clear tracking avoids omissions on the ground.
Keeping supporting documents: service reports, waybills, invoices and certificates
Archive signed service reports, tightness-check reports where applicable, waybills for recovered refrigerant collection, and refrigerant purchase invoices. Also keep the company's capability certificate and the technicians' proof of competence. Centralise everything, paper or digital. It's your evidence in the event of an inspection.
Setting up a simple routine to avoid log book gaps
Site checklist: when to fill in the log book (before, during, after)
To make this genuinely smooth, set 3 fixed moments. Before starting, open the log book with the address, dates, technicians, and quote references. During the job, note changes as they happen. After handover, close it out with the final evidence.
- Before. Photos of the existing setup, survey or site checks, plans, authorisations.
- During. Equipment installed (references, manuals), key steps, waste removal, unforeseen issues.
- After. Final photos, handover report, invoices, incentive certificates, technical data sheets.
Archiving and retention period: filing so you can find it in 2 minutes
Create one folder per job. Same structure everywhere. 01 Quotes, 02 Invoices, 03 Photos, 04 Certificates, 05 Waste. Name files with date and batch. Keep them at least as long as required for incentive checks and, for documents linked to work liability, up to 10 years.
Preparing for an inspection: gathering your traceability evidence without stress
On the day, the idea is simple. A PDF export of the log book, plus a pack of key evidence. Signed quote, invoice, product data sheets, dated photos, sworn statements, waybills. With that, you respond quickly, without digging through the whole van. If you don’t yet have a tool to produce that export, registre-fluides.argile.ai works out your threshold and generates the intervention sheet and the equipment log book as PDFs, with no account and without your entries ever leaving your device.

Practical cases: log book examples for your projects
Heat pump: tracking the charge and refrigerant top-ups across visits
On a heat pump, your log book keeps a clear line between the original charge and what you add. Note the refrigerant type (e.g. R32), the quantity in place, then each top-up, with the cause (fine-tuning, suspected leak, repair). To frame these additions, you can also refer to good practice for refrigerant charging.
- Date, site, equipment number, technician.
- Quantity added or recovered (kg) and tightness check.
- Result and next action, without promising anything, just recording it.
Multi-split air conditioning: traceability per unit and per intervention
On a multi-split system, avoid a "global" log book. Open one sheet per indoor unit and one for the outdoor unit. You link each intervention to the right traceability line, especially when several rooms are involved.
- Unit reference, pipe run length, refrigerant top-up if needed.
- Reason, measurements, and recommissioning.
End-of-life recovery: recording refrigerant collection and disposal
On removal, the log book must show the refrigerant's full path. Quantity recovered, packaging, then handover to an authorised operator. Keep the associated supporting documents, for simple proof in the event of an inspection.
- Recovery date and refrigerant mass (kg).
- Cylinder number, labelling, temporary storage.
- Recipient, waybill, treatment method.
