The Certificate III in Air-Conditioning and Refrigeration (UEE32220) is Australia's nationally recognised trade qualification for refrigeration and air-conditioning mechanics, delivered through a 3-4 year apprenticeship under ASQA-registered training organisations. It is competency-based: apprentices must be assessed 'Competent' across core and elective units through theory tests, practical demonstrations and on-the-job evidence rather than a single multiple-choice exam. Content spans the vapour-compression refrigeration cycle, refrigerants and ARCtick/F-gas handling, system components, electrical and controls for HVAC, psychrometrics, fault finding, and leak testing, evacuation and recovery, all referenced to AS/NZS standards. Legally handling refrigerant also requires a separate ARCtick Refrigerant Handling Licence. This free prep includes 100 research-based practice questions with explanations and an AI tutor.

About the Cert III Air Conditioning & Refrigeration Exam
The Certificate III in Air-Conditioning and Refrigeration (UEE32220) is the Australian trade qualification for refrigeration and air-conditioning mechanics. It is competency-based and delivered through a 3-4 year apprenticeship rather than a single exam, covering the vapour-compression cycle, refrigerants and ARCtick handling, system components, HVAC electrical and controls, psychrometrics, fault finding, and leak testing, evacuation and recovery.
Exam sponsor: Registered Training Organisations under the Australian Skills Quality Authority (ASQA). The requirements and fees below concern the certification or admission exam, separate from our free practice resources.
Assessment
Competency-based assessment across core and elective units (theory tests + practical + workplace evidence) over a 4-year apprenticeship; no single national multiple-choice exam. This practice bank is 100 selected-response trade-theory items.
Time Limit
Theory blocks across a 3-4 year apprenticeship (approx. 932 hours face-to-face plus on-the-job training)
Passing Score
Competency-based: 'Competent' required in every unit (no percentage pass mark)
Exam / Certification Fees
No standalone exam fee; course fees vary by state/RTO (often subsidised). ARCtick licence fee is separate.

Frequently Asked Questions
Is the Certificate III in Air-Conditioning and Refrigeration (UEE32220) a single exam?
No. UEE32220 is a competency-based trade qualification completed over a 3-4 year apprenticeship. Apprentices are assessed 'Competent' through theory tests, practical demonstrations and on-the-job evidence rather than one national multiple-choice exam. This bank is trade-theory knowledge-prep for those assessments.
Do I still need an ARCtick licence after the Certificate III?
Yes. To legally acquire, handle, recover or dispose of fluorocarbon refrigerant in Australia you must hold an ARCtick Refrigerant Handling Licence from the Australian Refrigeration Council, which is applied for separately. The qualification provides the underpinning competency.
How long does UEE32220 take to complete?
It is delivered over a typical 3-4 year apprenticeship, with around 932 hours of face-to-face training in blocks plus on-the-job training with your employer. There is no fixed exam date; you progress as you are assessed competent in each unit.
What topics does the Certificate III cover?
It covers the vapour-compression refrigeration cycle, refrigerants and ARCtick handling, system components, electrical and controls for HVAC, psychrometrics, fault finding and diagnostics, and leak testing, evacuation and recovery, all referenced to AS/NZS standards.
What is the difference between UEE32220 and UEE32225?
UEE32225 is the updated successor code to UEE32220 for the Certificate III in Air-Conditioning and Refrigeration. Both lead to the same refrigeration and air-conditioning mechanic trade; the core trade theory in this practice bank applies to either code.
Is this free practice as good as paid prep?
Our 100 practice questions cover the same trade-theory domains as the qualification and the ARCtick syllabus, with a teaching explanation for every answer plus free daily AI tutor interactions. All content is free forever and updated for 2026.
