Looking to keep your home cool without the constant hum of machinery in the background? At Melbourne Aircon Specialist, we know that a truly comfortable home isn’t just about temperature—it’s about peace and quiet, too.

If you're planning to install an air conditioner and want the quietest option available, this guide is for you.

Why Air Conditioner Noise Levels Matter

Air conditioning units can vary greatly in how much noise they produce. This noise is measured in decibels (dB)—the lower the number, the quieter the system.

To give you an idea:

🌿 30 dB – Equivalent to a whisper
🗣️ 60 dB – Normal conversation
✅ Below 50 dB – Considered quiet for AC systems

Noise Rules in Victoria

In Victoria, the Environment Protection Authority (EPA) enforces limits on noise from mechanical systems, including air conditioners:

Time of Day	Noise Limit	Regulation Summary
Day (7am – 10pm)	≤ 55 dB or +5 dB over ambient	Must stay within acceptable range near property line
Night (10pm – 7am)	≤ 45 dB or ambient level only	Tighter limits to ensure restful sleep

Quietest Air Conditioner Types Compared

Here’s a breakdown of some of the quietest air conditioning systems you can install, along with average noise levels:

Air Conditioner Type	Indoor Noise Level (dB)	Outdoor Noise Level (dB)	Why It’s Quieter
Split System (Ductless)	19–30 dB	45–50 dB	Quiet indoor unit, compressor is outside
Ducted Reverse Cycle	25–35 dB	50–60 dB	Ducts reduce sound, centralised operation
Window Unit (Modern)	50–60 dB	N/A	New models feature better fan tech
Portable Unit (Premium)	50–55 dB	N/A	Improved design, compact insulation
Central AC System	25–40 dB	50–70 dB	Indoor parts placed away from bedrooms

Why Go Quiet?

Here’s what a low-noise air conditioning system can offer:

🛏️ Better sleep and rest
🎓 Improved focus for work or study
🧘‍♂️ Lower stress and irritation
🏠 More relaxing living spaces
💼 Increased property value
