About the HVAC centre At Holmesglen’s HVAC Centre of Excellence, students learn in a simulated environment that replicates the entire heating, ventilation and air conditioning systems used in today’s climate-controlled buildings. As these systems become more sophisticated, technologically advanced and environmentally efficient, they require skilled workers to design, install, repair and maintain them. The Centre was established through a partnership between Holmesglen and Victoria’s peak mechanical contracting body, the Air-Conditioning and Mechanical Contractors’ Association (AMCA) and continues to operate with strong industry connections.
