Last year, MEA became aware of ongoing issues related to faulty pair coils, which have been causing micro-holes that lead to gas leakage. Despite the clear prevalence of these defects, manufacturers have frequently attributed the issue to installation errors, rather than recognising it as a manufacturing fault.

MEA has since engaged with ARCtik and the Department of Climate Change, Environment, Energy and Water (DCCEEW) to address these concerns and has received the following information:

• In 2023, the DCCEEW convened two advisory group workshops with industry peak bodies including suppliers, installers, and other experts on the concerns of leaking pair coil. The ACCC attended the advisory group to highlight the rights of technicians as consumers.
• Additionally, DCCEEW conducted an industry-wide survey focusing on pair coil issues, including questions on specific brands and observed defects. The results indicated that technicians expressed concerns about a range of pair coil types, with no single brand or style identified as being more prone to defects than others.

Following these investigations, the advisory group concluded that the issue of faulty pair coils should be addressed as a contractual matter directly with the manufacturer.

In 2024-25, DCCEEW worked with the Australian Institute of Refrigeration, Air-conditioning, and Heating (AIRAH) to review, update and publish the Stationary Refrigeration Handling Codes of Practice Parts 1 and 2. These revisions include more detailed guidance on best practices for pipework installation and maintenance.

MEA will continue to monitor the situation and keep members informed of any future developments.
