AIRAH is the only body solely focused on representing mechanical engineer – HVAC&R building services professionals.

The AIRAH Professional Engineer Register (APER) is the professional accreditation for engineers operating in the HVAC&R building services industry. It demonstrates to the public that an engineer is qualified, competent, and ethical.

AIRAH is an approved assessment entity for the Board of Professional Engineers of Queensland (BPEQ), and the Business Licensing Authority (BLA) in Victoria.

The APER is open to both AIRAH members and non-members. AIRAH members on the register may carry the post-nominal of AIRAH Registered Professional Engineer (ARPEng) – the practical mark of quality in engineering.
