Buying a new air conditioner is a major investment for any homeowner. Choosing the wrong system can lead to high electricity bills, poor cooling...
What Are the Quietest Air Conditioner Types to Install?
When it comes to creating a comfortable indoor environment, quiet air conditioning can make a big difference. Whether you’re working, relaxing, or trying to sleep, excessive noise can interrupt your peace. At Melbourne Aircon Specialist, we guide homeowners across Victoria in selecting air conditioning systems that combine efficient cooling with low-noise operation.
Why Noise Levels Matter
Air conditioner noise is measured in decibels (dB). A lower dB rating means quieter operation. To give you some context:
- 🌿 30 dB – Whisper
- 🗣️ 60 dB – Normal conversation
- ✅ Below 50 dB – Considered quiet for air conditioners
EPA Noise Regulations in Victoria
According to the Environment Protection Authority (EPA Victoria):
| Time of Day | Maximum Allowable Noise (dB) | Notes |
|---|---|---|
| Daytime (7am–10pm) | Background + 5 dB or ≤ 55 dB | Measured from the boundary of the property |
| Nighttime (10pm–7am) | Background + 0 dB or ≤ 45 dB | Stricter limits to ensure restful sleep |
