Understanding the Main Types of Air Conditioning Systems
There are three popular air conditioning options for Melbourne homes:
- Single Split System
- Multi Split System
- Ducted Air Conditioning System
Each system is designed for different home sizes and cooling requirements.
Comparison Table: Which Aircon System Is Best for You?
| System Type | Best For | Key Features | Ideal Rooms | Installation Cost |
|---|---|---|---|---|
| Single Split | One room | One indoor + one outdoor unit | Bedroom, study, living room | Lower |
| Multi Split | Multiple rooms | One outdoor + several indoor units | 2–5 rooms | Medium |
| Ducted System | Whole home comfort | Hidden vents + central control | Entire home | Higher |
1. Single Split System
A Single Split System is the most common and affordable option for homeowners who want to cool or heat one specific room.
Best For:

- Living rooms
- Home offices
- Small apartments
- Study rooms
Benefits:
✔ Cost-effective
✔ Easy installation
✔ Energy-efficient
✔ Quiet operation
✔ Ideal for small spaces
If you only need cooling in one area, this is often the best solution.
2. Multi Split System
A Multi Split System allows you to connect multiple indoor units to one outdoor unit.
Best For:
- Multiple bedrooms
- Double-storey homes
- Homes with limited outdoor space
- Families needing room-by-room control
Benefits:
✔ Individual temperature control
✔ Saves outdoor space
✔ Cleaner external appearance
✔ Flexible zoning options
This is perfect for households needing comfort across several rooms without installing multiple outdoor units.
3. Ducted Air Conditioning System
A Ducted System provides whole-home comfort using hidden ceiling vents and one central system.
