New rules aim to protect the climate and promote cleaner cooling solutions.
From 1 July 2025, Australia will introduce strict new rules that will change the way air conditioners are imported and sold. The government has decided to ban small multi-head split systems that use hydrofluorocarbons (HFCs) with a global warming potential (GWP) higher than 750. These chemicals are powerful greenhouse gases, and cutting them is an important step in slowing down climate change.
This decision builds on earlier bans covering portable, single-head, and wall-mounted units. Now, the restrictions will also include outdoor units for multi-head split systems and variable refrigerant flow systems, if they are designed to heat or cool indoor spaces for comfort, have a refrigerant charge of 2.6 kg or less, and use HFCs above the allowed limit. Even equipment that is imported without refrigerant is included if it is meant to use high-GWP gases.
The law comes under the Ozone Protection and Synthetic Greenhouse Gas Management Act 1989, which helps Australia meet its obligations under the Montreal Protocol, a global agreement to safeguard the ozone layer and reduce emissions. By removing outdated, climate-damaging systems, Australia hopes to encourage the use of safer alternatives such as R32 (GWP 675) and R-290 (propane).
The government is working with businesses to make sure they understand these rules, offering guidance so companies can prepare ahead and avoid penalties. Anyone importing or exporting controlled substances without the proper licence may face heavy fines, licence suspensions, or official warnings.
Looking ahead, these changes could push the air conditioning industry to adopt more sustainable technologies worldwide. Since Australia often sets strong environmental standards, its decision may inspire other countries to follow, creating a broader impact on climate protection, energy efficiency, and environmental responsibility.
Key Terms Explained
- Global Warming Potential (GWP): A measure of how much heat a greenhouse gas traps in the atmosphere compared to carbon dioxide. The higher the number, the more harmful it is.
- Hydrofluorocarbons (HFCs): Man-made gases used in cooling systems. They don’t harm the ozone layer but are powerful greenhouse gases.
- Montreal Protocol: An international treaty signed by many countries to protect the ozone layer and reduce harmful emissions.
