Air Conditioning Regulations in Victoria 2025 – A Complete Guide for Homeowners
Victoria’s weather can be unpredictable, shifting from scorching summers to cold winter nights. Having a reliable air conditioning system isn’t just about comfort—it’s also about ensuring your installation is done safely, legally, and in line with the latest regulations.
In this guide, Climate Green Melbourne breaks down everything you need to know about air conditioning regulations in Victoria for 2025. From licensing rules to noise restrictions, rental requirements, and rebate opportunities, here’s how you can stay compliant while keeping your home comfortable.
Professional Installation and Licensing Requirements
Licensed and Qualified Installers
Installing an air conditioner is not a DIY task in Victoria. The Victorian Building Authority (VBA) requires that only licensed professionals carry out installations. Installers must be registered in the refrigerated air conditioning class, ensuring they are trained in plumbing, drainage, and system mounting.
Additionally, the installer must hold a Refrigerant Handling Licence, issued by the Australian Refrigeration Council, to safely manage refrigerant gases.
Electrical Safety Standards
Since air conditioning systems involve electrical work, a licensed electrician must also be involved. For simple pre-wired connections, a restricted electrical licence may suffice. However, for new circuits or more complex wiring, only a Registered Electrical Contractor can legally perform the work.
After every installation, homeowners should receive:
- Plumbing Compliance Certificate – proof that all plumbing work meets VBA standards.
- Electrical Safety Certificate – ensuring the system is safe and ready for operation.
These certificates are crucial for safety, compliance, and keeping your manufacturer’s warranty valid.
Noise Regulations for Air Conditioners
Air conditioners must comply with the Environment Protection Regulations 2021 to minimise noise pollution.
You cannot run noisy air conditioners:
- Weekdays: before 7:00 am and after 11:00 pm
- Weekends & Public Holidays: before 9:00 am and after 11:00 pm
Additionally:
- Noise levels must not exceed 5 dB(A) above background noise at your property boundary.
- At night, levels should stay under 40 dB(A) in quiet residential areas.
During declared heat health emergencies, these restrictions are relaxed to prioritise public safety.
Rental Homes and Future Standards
While heating has long been mandatory in Victorian rental homes, cooling is becoming increasingly important. With Victoria’s push towards electrification and the phase-out of gas, reverse-cycle air conditioners are emerging as the preferred solution for both heating and cooling.
Though cooling isn’t legally required yet, many landlords are installing reverse-cycle units early to:
- Attract tenants
- Increase property value
- Stay ahead of future energy efficiency standards
Tenants can also benefit from the Victorian Energy Upgrades (VEU) rebate program, which lowers installation costs and supports the transition to efficient electric systems.
Safety, Efficiency, and Best Practices
To ensure safety and maximise efficiency, follow these best practices:
- Always use licensed professionals for installation and servicing.
- Switch off power before cleaning or inspecting your unit.
- Keep outdoor units clear of debris and obstructions.
- Clean filters regularly to maintain airflow and efficiency.
- Schedule routine servicing to detect unusual noises, odours, or faults.
- Ensure good ventilation to avoid stale indoor air and moisture issues.
A well-maintained air conditioner will last longer, consume less power, and provide better comfort.
