Mobile Air Conditioning Training for Technicians Launched in Tonga
19th March 2026, Nukuálofa – A pioneering training program on Mobile Air Conditioning (MAC) systems has been introduced in Tonga at the Tonga National University – Fokololo óe Hau School of Science and Technology marking the first of its kind in the country. This training was made possible through collaborations between Ministry of MEIDECC – Department of Climate Change with UNEP and other local counterparts including the MAC Technicians working in different organizations and private sectors. The initiative aims to equip local technicians with essential knowledge and practical skills to ensure safe practices, accurate diagnostics, and compliance with international environmental standards.
Traditionally, technicians have relied on repeatedly recharging air conditioning systems when cooling performance drops. This training challenges that approach by teaching participants how to properly diagnose underlying issues, thereby reducing unnecessary refrigerant use and promoting safer and sustainable practices.
A key component of the program is raising awareness of international agreements such as the Montreal Protocol, which regulates substances that deplete the ozone layer. By aligning with these global requirements, Tonga is taking an important step toward environmental responsibility and climate protection.
The training emphasized the importance of using basic diagnostic tools and knowledge. Technicians were shown how to apply manifold gauges to measure system pressure, and how to check cooling performance by setting the temperature valve to high while running the engine at approximately 1500 RPM for one minute. This simple procedure helps determine whether refrigerant remains in the system, ensuring accurate diagnosis before any recharging is considered. Such practices not only save costs but also prevent unnecessary emissions of refrigerants into the atmosphere.
The program was attended by local technicians eager to expand their expertise in MAC systems. Participants gained hands-on experience, technical insights, and a deeper understanding of the environmental impact of their work. There is high hope that this initiative will continue in the future, fostering a network of skilled technicians who can uphold international standards while serving Tonga’s growing automotive sector.
“This training is not only about improving technical skills, it’s about protecting our environment and ensuring Tonga meets its international commitments,” said Mr. Moilisi Kilisimasi (Facilitator) “We are proud to see technicians embracing this new knowledge and look forward to ongoing engagement in the MAC sector.”
The program represents a milestone in Tonga’s efforts to build capacity in sustainable technology and highlights the importance of continued collaboration between technicians, policymakers, and international partners.
