Choosing the right air conditioning system for your home can be tricky, especially with so many options available. The two most popular systems—ducted air conditioning and split air conditioning—each come with their own advantages. So, how do you decide which one is best for your needs?
In this guide, we’ll break down the key differences, benefits, and considerations of ducted and split air conditioning systems to help you make the right choice for your home.
Understanding the Basics
What Is Ducted Air Conditioning?
Ducted air conditioning systems provide centralised cooling or heating for your entire home. They use a single outdoor unit connected to a network of ducts installed in the ceiling or walls. These ducts deliver conditioned air through vents into each room.
What Is Split Air Conditioning?
Split air conditioning systems are designed to cool or heat individual rooms. They consist of an indoor unit mounted on a wall and an outdoor unit that powers the system. They’re commonly used in single rooms or smaller spaces.
Benefits of Ducted Air Conditioning
Whole-Home Comfort
- Provides consistent temperature control throughout your entire home.
- Ideal for larger homes or open-plan layouts where multiple areas need to be cooled or heated.
Aesthetic Appeal
- Ducted systems are discreet, with vents that blend seamlessly into your ceiling or walls. There are no bulky indoor units to take up wall space.
Zoning Capabilities
- Advanced ducted systems allow you to create zones, enabling you to cool or heat specific areas of your home. For example, you can focus on bedrooms at night and living areas during the day.
Quiet Operation
- With the main components installed outside or in the ceiling, ducted systems are quieter than most split systems.
Benefits of Split Air Conditioning
Cost-Effective
- Split systems are significantly cheaper to install compared to ducted systems, making them a great choice for budget-conscious homeowners.
Targeted Cooling and Heating
- Perfect for cooling or heating specific rooms, such as bedrooms or living rooms, without wasting energy on unused areas.
Energy Efficiency
- Split systems consume less energy when cooling or heating individual rooms, particularly for smaller homes or apartments.
Easy Installation
- Installation is simpler and quicker compared to ducted systems, as it doesn’t require extensive ductwork.
Comparing Costs
Ducted Air Conditioning Costs
- Upfront Installation: $5,000–$10,000+ (depending on home size and complexity).
- Running Costs: Higher due to whole-home coverage but can be reduced with zoning.
Split Air Conditioning Costs
- Upfront Installation: $600–$3,500 per unit + $600–$800 installation cost.
- Running Costs: Lower for single-room use, making it more energy-efficient for targeted cooling.
Energy Efficiency: Ducted vs Split Systems
Ducted Systems
- Most ducted systems from brands like Daikin and Mitsubishi Electric now feature inverter technology, which improves energy efficiency.
- Zoning options reduce energy consumption by allowing you to cool or heat only specific areas.
Split Systems
- Split systems are ideal for energy-efficient cooling in smaller spaces. Many models come with high energy star ratings and eco-modes to minimise power usage.
Key Considerations for Your Home
1. Home Size and Layout
Ducted Systems: Best for larger homes or open-plan layouts requiring whole-home temperature control.
Split Systems: Perfect for smaller homes, apartments, or individual rooms.
2. Budget
- Ducted systems are a larger upfront investment, while split systems are more affordable initially.
3. Aesthetic Preferences
- If you prefer a minimalistic look with no visible wall-mounted units, ducted systems are the better choice.
4. Usage Patterns
- If you only need to cool or heat specific areas (e.g., a bedroom or living room), a split system is more practical.
Why Choose Daikin or Mitsubishi Electric?

Making the Final Decision
Here’s a quick summary to help you decide:
| Feature | Ducted Air Conditioning | Split Air Conditioning |
| Best For | Whole-home cooling and heating | Individual rooms |
| Upfront Cost | High | Moderate |
| Energy Efficiency | Good with zoning | Excellent for small spaces |
| Installation | Complex and time-intensive | Simple and quick |
| Aesthetic Appeal | Discreet with no visible units | Visible indoor unit |
Why Professional Installation Matters
Whether you choose a ducted or split system, professional installation is essential to maximise performance and efficiency. Local installers in areas like Charmhaven, Tuggerah, or Terrigal understand the unique challenges of Central Coast homes, such as coastal air and humidity, and can ensure your system is installed correctly.
Final Thoughts
Choosing between ducted and split system air conditioning ultimately depends on your home, budget, and lifestyle in Central Coast. For larger homes with whole-home cooling needs, ducted systems are ideal. If you’re focusing on individual rooms or prefer a more cost-effective solution, a split system is the way to go.
