Air Conditioning Maintenance and Fluorinated Greenhouse Gases.
Air Conditioning Maintenance & F-Gas Compliance

Air Conditioning Maintenance and Fluorinated Greenhouse Gas (F-Gas) Compliance

Keep cooling assets efficient, reliable and compliant. This factsheet outlines practical maintenance requirements, statutory F-Gas duties, record-keeping standards and competence expectations for systems containing fluorinated greenhouse gases.

Maintenance regimes are defined in accordance with SFG20 and manufacturer guidance, with independent system performance and energy compliance assessed under CIBSE TM44 where applicable.

At a glance
  • Maintenance aligned to SFG20 and manufacturer instructions.
  • Independent energy and compliance assessment under CIBSE TM44 where applicable.
  • Leak checking based on refrigerant CO2e thresholds.
  • Full traceability through asset registers and digital logbooks.
  • Only certified organisations and personnel may handle refrigerants and recovery.
Core maintenance tasks
  • Visual inspections: pipework, insulation, supports, casings and vibration.
  • Airside: filters inspected or replaced, coils cleaned, fans and drives checked.
  • Controls: sensors, calibration, setpoints, safeties and alarms reviewed.
  • Refrigerant circuit: leak indicators, operating pressures, temperatures and general condition checked.
  • Condensate: trays, traps and drains cleared and treated as required.
F-Gas compliance

Systems containing fluorinated greenhouse gases must be managed in accordance with the applicable Fluorinated Greenhouse Gases Regulations and associated guidance.

  • Leak-checking frequency is determined by the system refrigerant charge expressed in CO2e.
  • Detected leaks must be repaired without undue delay and re-tested to verify the repair.
  • Refrigerant must be recovered during service, decommissioning and prior to disposal.
  • Equipment must be correctly labelled with refrigerant type and charge.
  • Records must be maintained showing refrigerant quantities, additions, removals, leak checks and engineer details.
Maintenance strategy and delivery model

Maintenance by Global operates as a compliance authority and system architect, with service delivery undertaken through approved Third Party Engineers (TPEs).

  • Maintenance scope is defined through technical audit and asset review.
  • Planned tasks are scheduled in accordance with asset criticality, condition and manufacturer guidance.
  • F-Gas works are allocated only to appropriately certified contractors.
  • Completed works, refrigerant movements and compliance evidence are verified and retained centrally.
Records and evidence

A compliant air conditioning system requires a complete and auditable record set.

  • Asset register including refrigerant type, charge and CO2e calculation.
  • Maintenance and leak-check records with outcomes and remedial actions.
  • Refrigerant transfer, recovery and disposal certification.
  • Competence records for all organisations and personnel handling refrigerants.
  • Relevant environmental procedures and safe systems of work.

These records are retained within the Logbook Portal to provide a permanent compliance history for each asset.

Refrigerant handling and disposal

Fluorinated gases, including common HFC refrigerants, are potent greenhouse gases and must be strictly controlled.

  • Refrigerant recovery is undertaken by certified personnel only.
  • Recovered refrigerant is transferred to appropriately licensed recycling or disposal routes.
  • Disposal and transfer documentation is retained as part of the client logbook record.
Competence requirements

Any organisation or individual undertaking refrigerant handling must hold the required certification.

  • Engineer-level certification, such as City & Guilds 2079 or equivalent recognised qualification.
  • Company-level F-Gas certification held by the contracting organisation.
  • Verification of competence retained within the asset and contractor records.

Under the current delivery model, these competencies are held by appointed TPE contractors and checked as part of supplier assurance.

Regulatory and inspection context

Air conditioning maintenance sits within a wider compliance framework that includes environmental control, system efficiency and periodic inspection.

  • SFG20 provides the planned maintenance baseline.
  • Manufacturer instructions define equipment-specific servicing requirements.
  • CIBSE TM44 supports inspection of system performance and energy efficiency where applicable.
  • Applicable F-Gas legislation governs refrigerant containment, leak checking, recovery and records.
Roles and responsibilities

Duty holders are responsible for ensuring that systems are identified, maintained, inspected where required, and supported by complete compliance records.

  • Provide safe access and relevant asset information.
  • Ensure works are undertaken by competent and certified personnel.
  • Maintain environmental stewardship through refrigerant control and proper disposal.
  • Retain evidence sufficient to demonstrate compliance at any time.
