F-gas records: how HVAC firms can use AI to keep them in order
Use AI to draft service reports from site notes and turn an asset list into a visit plan. It can also sort the records your team keeps for F gas. Start with the work done and the service tasks your team has agreed.
For a heating, ventilation and air conditioning firm, link each draft to an asset ID. This connects the visit, fault note, parts order and next booking. Begin with one site whose service records you already hold.
Draft a service reportLink service reports, maintenance plans and records to each asset.
Turn the site note into a useful service report
Use headings for site, asset ID, date, work done and readings. Add open items and the next action. Ask AI to sort the notes and put a short client summary at the top.
More on this step
Keep the engineer’s findings distinct from the work done and the advice given. If the note asks for a parts quote, put it under follow-up work. Keep the service tasks together so the client can see what the visit covered.
Link photos and other records using the asset ID. Give each open action a person in charge and a due date. The service desk can then turn it into a parts request or a return visit. Keep the full site note with the report.
Worked example
One note produces a client report and an office action
Example with made-up details: AHU-04, west office, filters replaced, belt wear noted. Replacement belt quote requested. Photos 18 and 19. Engineer to confirm part code.
The report summary reads: We replaced the filters on AHU-04 during this visit. The engineer noted belt wear and requested a quote for a new belt. Photos 18 and 19 are attached. Our service desk will draft the quote once the part code is confirmed.
The office action reads: AHU-04 belt quote; await part code from site engineer; attach photos 18 and 19; send quote to site contact. Both outputs carry the same facts. The office can see which detail is needed before it sends the quote.

Plan visits from the asset register
Give AI the assets, locations, agreed service intervals and last visit dates. Add the tasks from the service plan and maker’s guidance. Ask it to group the work by month and site.
Use columns for asset ID, task, due date and source of the interval. Add the access window, time needed and assigned team. Group nearby work where access allows it. Keep a proposed date distinct from a visit the client has booked.
Prepare a monthly client view with planned visits and access details still needed. Keep the task instructions in the engineers’ work pack. After each visit, update the asset history. Use the latest work record when planning the next round.
Index the F-gas records with the service visit
GOV.UK lists the F-gas equipment in scope and the records to keep. For covered equipment, these include gas type and quantity and gas added during maintenance. They also cover mandatory leak-check dates and results, plus gas recovery and disposal.
Use those fields to index the records your engineers supply. Add the asset ID, service date and source link. Ask AI to list empty fields so the service desk can obtain the source record.
The guidance specifies five-year retention for the listed records. It also covers records of the companies used. Check the rules for your equipment and location. Build the agreed retention period into the system. Link each F-gas record to the same asset and visit as the service report.

Qualified staff confirm the engineering record
GOV.UK sets out qualifications for F-gas work. Assign that work to staff with the required qualifications. The engineer confirms readings, leak-check results, diagnosis and advice before the report is issued.
The service manager approves the tasks and intervals. They use the contract, maker’s guidance and inspection requirements that apply. Use AI to arrange the agreed tasks and dates in the plan.
Consult the ICO’s guidance when AI tools handle site contacts and staff data. Use approved tools for site contacts and staff records. Match access to the work each team member needs to do. Keep the original site records with the approved report.

Prepare a service report for asset [ID] at [site]. Use these notes [notes] and our headings [headings]. Keep readings, units and part codes exactly as supplied.
Write the client summary, work done, findings and follow-up tasks. Link each photo ID to the right finding. Put unanswered parts or access questions in an office action list.
Use this approved service plan [tasks and intervals] to draft the next visit. Include the asset, due date, access window and team. Extract these F-gas records [records] into our asset log. End with the fields and source files still needed.
Questions about this task
What if our site notes are brief?
Agree a note format with asset, work, findings and follow-up. A dictated note can use those headings. Add readings through your usual recording method and link them to the visit.
Can we generate a full annual schedule?
Supply the agreed tasks and intervals for every asset. Ask for a monthly plan. Review access and team capacity before booking visits, then refresh the plan as work enters the asset history.
