Victoria’s weather swings between extreme summer heat and chilly winter nights, making air conditioning a necessity for comfort. But installing a system isn’t just about picking the right brand—it’s also about following the legal and safety requirements in place.

This guide from Climate Green Melbourne breaks down the air conditioning regulations every homeowner should know in 2025, helping you stay comfortable while remaining compliant.

Licensed Installation – Why It’s the Law

Victorian Building Authority (VBA) Requirements

Air conditioner installation in Victoria must be done by licensed professionals, not DIY enthusiasts. Installers need to be registered with the VBA and:

Hold a licence in refrigerated air conditioning.
Be qualified to handle drainage, pipework, and system mounting.
Carry the correct class of licence for the type of system installed (split, ducted, or advanced units).

Refrigerant Handling Licence

Installers must also carry a Refrigerant Handling Licence issued by the Australian Refrigeration Council (ARC). This ensures refrigerants are handled safely, protecting both the environment and your system.

Electrical Safety Compliance

Air conditioning involves electrical connections, which must be done by a licensed electrician or qualified contractor.

When your installation is complete, your installer must provide:

An Electrical Safety Certificate – confirming wiring meets standards.
A Plumbing Compliance Certificate – ensuring installation complies with regulations.

These certificates are essential for both legal compliance and keeping your manufacturer’s warranty valid.

Noise Rules for Air Conditioners in Victoria

Victoria has clear rules to keep air conditioner noise levels under control.

Under the Environment Protection Regulations 2021:

Weekdays – No noisy operation before 7:00 am or after 11:00 pm.
Weekends & Public Holidays – No noisy operation before 9:00 am or after 11:00 pm.

Other key standards include:

Noise should not exceed 5 dB(A) above background noise at your property line.
In quiet areas, night-time noise should stay under 40 dB(A).

⚠️ During extreme heat health alerts, these restrictions may be eased so households can stay safe.

Rental Properties and Upcoming Energy Standards

Air conditioning is playing a bigger role in Victoria’s rental property rules.

Heating has long been mandatory, but reverse-cycle air conditioners are being promoted since they deliver both heating and cooling.
Many landlords are choosing to upgrade early to meet future minimum standards and make properties more appealing to tenants.
With gas being phased out, rebates from the Victorian Energy Upgrades (VEU) Program make switching to efficient electric systems more affordable.

Safety, Maintenance & Best Practices

To keep your system efficient and long-lasting, follow these essential practices:

Always hire licensed professionals for installation or servicing.
Switch off power before cleaning or checking the unit.
Clear outdoor units of debris and ensure good airflow.
Clean indoor filters every few months.
Pay attention to unusual noise, odours, or tripped breakers.
Ensure rooms are well ventilated to maintain fresh air.

Regular maintenance improves energy efficiency, lowers running costs, and extends system lifespan.
