What is the AIRAH Professional Engineer Register?

The AIRAH Professional Engineer Register (APER) is the professional accreditation designed for engineers operating in the HVAC&R building services industry.

Why should I apply to be on the APER?

Australia’s states are introducing professional registration schemes for engineers (see more). A successful application to become listed on the APER will display to the industry – and to the public at large – your qualifications and commitment to the discipline. An APER listing confirms that your skills, professional development, and training are up-to-date, and that you are a qualified professional.

Why was APER introduced?

The APER accreditation supports AIRAH's ongoing advocacy work for professional registration. It also support the Institute's mission of creating an Australian HVAC&R industry that is highly skilled and professional, safe, sustainable and environmentally effective.

Australia’s states are introducing professional registration schemes for engineers. The Queensland Professional Engineers Act has been in operation since 2002. Victoria has introduced the Professional Engineers Registration Act 2019 to align with the Queensland scheme, starting on July 1, 2021. And New South Wales has introduced the Design and Building Practitioners Act and Regulation, commencing on July 1, 2021.

As a result of these Acts, engineers will need to be registered if they provide “professional engineering services”.

The schemes have been founded on the principle that a minimum level of qualifications, experience, and continuing professional development are required to carry out professional engineering services. The APER accreditation scheme has been developed to meet these requirements.

What does the ARPEng post-nominal signify?

AIRAH members who have successfully achieved APER accreditation are able to use the AIRAH Registered Professional Engineer (ARPEng) post-nominal.

What is HVAC&R?

HVAC&R stands for heating, ventilation, air conditioning, and refrigeration. As an industry, it is an essential service that shapes our cities and towns and impacts daily life in a number of surprising ways.

Applicable to both residential and commercial buildings, HVAC&R refers to the systems used to move air. It includes, but not is limited to, technology that is used to warm/cool space.

For more information on HVAC&R, please download the What is HVAC&R? flyer and watch our video.

What is HVAC&R’s role in Australia?

In Australia, the industry is worth over $38 billion, uses more than 24% of the country’s electricity, and accounts for 11.5 per cent of our carbon dioxide emissions.

Despite playing a major role in global emissions, HVAC&R isn’t often a phrase associated with climate change. But the refrigeration and HVAC industry intersects with it in a number of ways. Click here to learn more about HVAC&R and climate change.

What are my career prospects in the industry?

In Australia alone, HVAC&R employs more than 298,000 people – and it’s still growing.

Where can I get information about refrigerant handling licensing?

An ARCTick licence is required across all jurisdictions when undertaking refrigeration and air conditioning work involving ozone-depleting refrigerants. Refrigerant handling licences are issued and controlled by the Australian Refrigeration Council (ARC). Click here for details.

Where can I get information on contractor/business-based licensing for refrigeration and air conditioning?

While the ARCTick licence system is a national Commonwealth requirement (i.e., an ARCTick licence is required in all jurisdictions), not all states and territories have occupational or business licensing for refrigeration and air conditioning contractors. A Mutual Recognition Act 1992 (MRA) entitles people holding an occupational licence or registration in one state or territory to an equivalent licence in another state or territory provided the work is licensed in both. See this website.

The following is a jurisdictional summary of licensing requirements in all jurisdictions.

  • Australian Capital Territory – The ACT does not license refrigeration and air conditioning work.
  • New South Wales – NSW issues air conditioning and/or refrigeration licences at both the contractor and qualified supervisor certificate levels.
  • Northern Territory – The NT does not license refrigeration and air conditioning work, but technicians must obtain a restricted electrical licence.
  • Queensland – Qld licenses refrigeration and air conditioning work through the Queensland Building Services Authority (regulated as part of the building occupations).
  • South Australia – In SA, regulation of refrigeration and air conditioning occurs through the building occupations where the primary focus of licensing surrounds the structural integrity of the installation of a refrigeration and air-conditioning unit in a building (that is the mounting of the unit and strengthening of trusses where required).
  • Tasmania – Tas licenses refrigeration air conditioning work under its plumbing regulations.
  • Victoria – Vic regulates refrigerated air conditioning as a specialised plumbing class, and this is issued as an ‘endorsement’ at the registration and licence levels.
  • Western Australia – WA does not license refrigeration and air conditioning work, but technicians must obtain a restricted electrical licence.

Where can I get information about noise issues?

Each state and many local government areas (local councils) have rules and regulations dealing with noise from air conditioning systems and other sources of environmental noise. Typically, councils have the power to stop people using air conditioning or to relocate systems if they are deemed too noisy, so it is important to get it right when initially installed.

AIRAH produced a Residential Air Conditioning Best Practice Design Guide focused on noise issues associated with this application. This guide is a voluntary document to help owners and installers mitigate any noise issues. It is available to download for each state, free from the AIRAH website.

You should contact your local council initially, as it will be able to clarify the specific regulation that applies in its jurisdiction and assist with the environmental noise-evaluation process.

AIRAH's FairAir website also contains size, noise and energy calculators for residential air conditioners, which may be of use. For help using the FairAir website, please watch our tutorial video.


My air conditioner doesn't work. What can I do?

AIRAH is not able to assist with air conditioning repairs. We recommend you try to contact your provider or the product manufacturer for assistance. You may also be able to find further help and/or guidance from companies on HVAC&R Search.
