Robert Michalak speaks about the Graduate Training Program

  • Suitable for recent mechanical engineering graduates, or those with significant experience in associated fields of HVAC&R, who are seeking to better understand engineering processes.
  • Competency-based assessment, verifying that each student is self-motivated and prepared to work effectively under senior guidance, at a graduate level in the HVAC&R industry.
  • Outsourced training opportunity for HVAC&R businesses committed to the development of their graduates.
In addition to the theory content provided across four key training areas, the program takes students on a journey of designing an HVAC system over 12 assignments. Feedback from experienced engineers is provided at every step

It provides an in-depth look at the overall journey of an HVAC&R mechanical engineer’s job. Practical takeaways include: reviewing a site, presenting design options to a client, calculating heat loads (manually, from basic principles), selecting equipment, designing, compliance assessment, budgeting, energy reporting and pulling together a tendering document. 

This program requires students to both read the course materials and demonstrate their readiness to operate in real world projects. Students are required to undertake their own research to determine answers to design problems. The use of outside course materials will be required, such as finding suppliers’ specification guidelines. Based on industry guidance, successful participants will exhibit initiative, curiosity and creativity in their assignments.

Program Snapshot
  • This program has established itself as the most important education and training tool for HVAC&R industry professionals.
  • Over 370 students have undertaken the program
  • Two intakes each year (max. 45 registrations per intake) 
  • Program frequently sells out; waiting list placement available.

Here's what some of our course participants have said about their experience:

“The AIRAH Professional Diploma in Building Services has been a terrific resource for greater understanding of the HVAC&R industry. It is full of information that bridges the gap between fundamental engineering knowledge and specific applications for HVAC&R engineering and building services.”

Daniel Waack, Engineer, A.G. Coombs (Projects)

“I have been able to utilise the knowledge gained from the AIRAH Professional Diploma in Building Services in my workplace, starting from design development to design reviews. This course has not only given me added confidence but also has allowed me to utilise my knowledge to deliver infrastructure projects effectively and more sustainably. I would recommend this course to anyone who is interested in starting their career in HVAC&R. It’s a great place to start!"

Nithiya Mohan, Project Officer, Capital Facilities & Infrastructure, Department of Defence

“The AIRAH Professional Diploma in Building Services directed my tertiary studies more specifically towards the HVAC&R industry. It has also given me the opportunity to learn from industry leaders and connect with other graduates like myself.”

Jackson White, Edwards & Vickerman Consulting Engineers

“The course is demanding but flexible, allowing you to progress through the 12 case studies assessments at your own pace. Each assessment has something unique to offer, enabling you to gain technical knowledge that can be applied immediately to your daily work. I found myself engaged throughout the entire course, from the initial site visit of a commercial building up to the submission of a complete scope of works documentation suitable for tendering. I appreciate the detailed feedback provided for every assessment from the experienced assessors. It offered me guidance on design processes and helped to reinforce my knowledge. To anyone thinking to start a career in building services, I highly recommend this course.”

Omar Arquimedes Hostia Sotil, Design Engineer, Temperzone Australia
