Air Conditioner Noise Limits in Victoria: What Every Homeowner Should Know

When it comes to staying cool during Melbourne’s warm months, an efficient air conditioner is a must—but it shouldn't come at the cost of peace and quiet. Under the Environment Protection Act 2017, air conditioners in Victoria must meet strict noise standards to ensure minimal disruption in residential areas.
At Climate Green, we help you install systems that are both energy-efficient and noise-compliant—so you stay comfortable and within the law.
📏 Understanding Air Conditioner Noise Regulations
The Environment Protection Authority (EPA) of Victoria has set a noise limit that your air conditioning unit must not exceed. Specifically, the sound level must be no more than 5 decibels above the background noise when measured inside your neighbour’s home.
✅ For example: If the ambient background noise is 40 dB, your system should not produce more than 45 dB at your neighbour’s property line.
🚨 How to Tell If Your Aircon Is Too Loud
Here are some common indicators your unit might be too noisy:
Normal conversations become difficult near the unit
You frequently increase TV or music volume
Vibrations are felt in nearby walls or floors
Neighbours voice concerns or complaints
Sudden increase in the unit’s operational noise
📱 A basic decibel meter app or a professional noise check from Climate Green can give you a clear answer.
🔇 What Are the Quietest Air Conditioning Systems?
Today’s best systems are designed to be efficient and whisper-quiet. These include:
Split-system units
Ducted reverse cycle systems with inverter technology
Modern heat pumps
These can operate between 20–30 dB, similar to a whisper, whereas older or less efficient units may exceed 60 dB—a level that could violate noise regulations.
🔧 How to Reduce Your Air Conditioner’s Noise
There are simple steps you can take to ensure quieter operation:
Get your system professionally installed and levelled
Clean or change air filters regularly
Secure any loose screws or panels
Install anti-vibration mounts
Create a sound barrier or fence around the outdoor unit
Book regular maintenance with Climate Green’s expert team
