In Victoria, maintaining peaceful neighbourhoods is a top priority—and that includes how loud your air conditioning unit can be. With new guidelines under the Environment Protection Act 2017, it’s essential for homeowners to understand how air conditioner noise is regulated and how to stay compliant.

What Does the Environment Protection Act Say?

The Environment Protection Authority (EPA) Victoria has clear rules around environmental noise. According to the Act, air conditioner noise must not exceed the background noise level by more than 5 dB when measured from a neighbour’s home.

For example, if the background noise in your neighbour’s home is 40 dB, your air conditioning system should not emit more than 45 dB from their property.

How Do You Know If Your Air Conditioner Is Too Loud?

Watch out for these warning signs:

• You struggle to hold a conversation near the unit
• The TV volume needs to be increased when the AC is running
• Walls or floors vibrate
• Neighbours have raised complaints
• There’s a noticeable rise in the unit’s operating noise

Tip: Use a smartphone decibel meter or get a professional noise check from experts like Climate Green.

What Are the Quietest Aircon Options?

Modern split systems and variable-speed central air conditioners are among the quietest. They can operate at 20–30 dB, which is quieter than a whisper. In contrast, older or window-mounted units can go above 60 dB, which may breach EPA guidelines.

Climate Green supplies and installs premium models that meet both performance and noise standards.
