The document outlines the activities of AREA, a pan-European association for contractors in refrigeration, air conditioning, and heat pump sectors, focusing on training, certification, and the transition to alternative refrigerants. It highlights the need for training in low GWP refrigerants, the introduction of an 'international observer' membership for global access to expertise, and the association's extensive training initiatives and international collaborations. Additionally, it emphasizes the importance of regulatory compliance and the preparations for new refrigerant technologies within the industry.

13. Contractors’ training with low
GWP refrigerants: mind the gap!
Kigali Amendment includes measures in favour
of a decreased use of HFCs in RACHP
equipment. Such measures would, in turn, result
in an increased use of alternatives, namely low
GWP (global warming potential) refrigerants,
and in particular the so-called “natural
refrigerants” (CO2, hydrocarbons and
ammonia). Mindful of the key role played by
contractors in the safe, efficient and reliable
functioning of equipment working with natural
refrigerants, AREA sought an overview of the
availability and level of training in the EU.
Solution could be starting from the F-Gas certification
of personnel adding modules for natural refrigerants
In EU:
Report of EU commission presented at
Consultation Forum 1st December

14. Why and how to create the need for
Training, Assessment, Certification
Certification is an important tool for the industry of RAC sector
Or legislatively imposed:
• Reducing Refrigerant Emissions, GHG, ODS
• Increasing energy efficiency (reducing CO2)
Or Industry-driven:
• More aggressive competition requires proof of higher quality and certification
Or Customer-driven:
• Wholesalers, distributors, big customers … require environmentally friendly and energy
efficient products
• Protects the interests of customer through
providing services according to applicable standards
 Certification of the personnel and
of the companies who handle air conditioning,
refrigeration and heat pumps equipment

15. On the experience of EU Refrigerants Certification
• The Basis is the Certification on HCFC,
HFC throught the Fgas EU regulation
• On top of it in EU we add the
certification on the alternative
refrigerants:
- Carbon Dioxide
- Hydrocarbons
- Ammonia
- HFOs & R32
Spain, Netherlands, UK
With the support of EU Commission but
not recognized in the whole EU,
every Member States legislate individually

Multiple answers tests, between 30 and 45 questions for 60-90 minutes duration (Sample questions in annex V)
The same test among candidates with variation of questions to prevent predictability among candidates
Closed books, only specific technical tools such as calculator and pressure-temperature comparator allowed
NO! mobile phones or cameras NO! copying or communication between candidates
YES! speaking to the assessor to ask explanation of the modalities and of the questions if not understood; many
candidates use different words and vocabulary to identify the same concept (eg. Valves)
Theoretical assessment: Pass mark above 60% correct answers
Laboratory should be properly equipped for performing
the practical test (see Annex IV of Certification Booklet)
Practical assessment: Pass if candidate proves competence
in performing main RAC service technicians activities
without or with only small hesitations (remember candidates
could be knowledgeable but be nervous!):

devices, temperature, pressure, subcooling, superheating
• Parameters interpretation, troubleshooting
• Perform a leak test
• Vacuum, charge, recovery with minimum emissions
• System Logbook reading, understanding and competition
• Brazing leak tight joints

organization issues

23. • Assessors and Trainers should hold a certificate
• Assessors should have multiple years of experience in the field
• Assessors should be comfortable in trainees’ evaluation
• Please see International Standards as ISO 17024 for more details
N.B in order to confirm the value and guarantee the sustainability of the
certification, standards must be kept high and therefore not everyone will
pass the exam!
