Which Is Best for You: Split System vs Ducted Air Conditioners
When choosing air conditioning for your home or business, one of the biggest decisions is whether to install a split system or a ducted air conditioner.
Both options are widely used across Perth. Both provide heating and cooling. But they are designed for different property types, layouts and usage needs. This guide breaks down the differences clearly so you can decide which system suits your space, budget and long term plans.
What Is a Split System Air Conditioner?
A split system consists of:
- An indoor unit mounted on a wall, floor or ceiling
- An outdoor compressor unit
- Refrigerant piping connecting the two
Each indoor unit controls one room or one open area.
Split systems are commonly used in:
- Bedrooms
- Living areas
- Apartments
- Small offices
- Granny flats
They are ideal when you only need to cool specific rooms rather than the entire property.
What Is a Ducted Air Conditioning System?
A ducted system uses:
- A central indoor unit installed in the ceiling space
- An outdoor compressor
- A network of ducts distributing air to multiple rooms
Air is delivered through ceiling vents in each room, with a central controller managing temperature and airflow.
Ducted systems are designed for:
- Larger homes
- Double storey properties
- Whole-of-home climate control
- Commercial spaces
They provide consistent heating and cooling throughout the entire building.
Split System vs Ducted: Key Differences
1. Coverage and Control
Split System:
Cools or heats one room per unit. If you need multiple rooms cooled, you will require multiple units.
Ducted System:
Controls the entire home or building from one central system.
If you only use one or two rooms regularly, split systems are practical. If you want seamless comfort across every room, ducted systems are more suitable.
2. Installation Costs
Split Systems:
Lower upfront cost per unit.
More affordable for single-room installations.
However, if you install several split systems across a large home, the total cost can approach that of a ducted system.
Ducted Systems:
Higher initial investment due to ductwork, ceiling installation and system design.
More cost effective when cooling the entire property.
If you are building or renovating, installing ducted air conditioning during construction is often more efficient.

3. Appearance and Design
Split Systems:
Indoor wall units are visible in each room.
Ducted Systems:
Only discreet ceiling vents are visible.
For homeowners who want a clean, minimal look, ducted air conditioning is often preferred.
4. Energy Efficiency
Energy efficiency depends on how the system is used.
Split Systems:
Highly efficient when cooling a single room.
Less efficient if multiple units are running simultaneously.
Ducted Systems:
Efficient for whole-home cooling.
Can be even more efficient when combined with zoning, allowing you to cool only occupied areas.
Proper system sizing plays a major role in efficiency. An undersized unit will struggle in Perth’s heat. An oversized unit can waste energy.
Before choosing a system, it is worth checking what capacity suits your space using the air con size calculator.
5. Noise Levels
Both systems are designed to operate quietly. Split systems air conditioners may produce slightly more noticeable indoor sound due to the wall-mounted unit. Ducted systems are generally quieter inside rooms, as the main unit is located in the ceiling cavity.
Which System Is Better for Perth Homes?
Perth’s long, hot summers mean air conditioning is essential, not optional.
A Split System May Be Right If:
- You live in a small home or apartment
- You mainly use one or two rooms
- You want lower upfront costs
- You prefer individual room control
A Ducted System May Be Better If:
- You want whole-home climate control
- You are building or renovating
- You value discreet aesthetics
- You want centralised temperature management
What About Commercial Properties?
For offices, retail spaces and larger commercial buildings, ducted or larger-scale systems are often more practical.
Commercial spaces typically require:
- Even temperature distribution
- Consistent airflow
- Reliable performance during long operating hours
If you are considering air conditioning for a business, explore commercial air conditioning solutions tailored to larger properties
Long Term Value and Property Appeal
When comparing split system vs ducted air cons, think beyond the initial price.
Consider:
- Ongoing running costs
- Maintenance requirements
- Future resale value
- Lifestyle convenience
Ducted air conditioning is often viewed as a premium feature and may increase property appeal in many Perth suburbs. Split systems, however, offer flexibility and targeted cooling where full-home coverage is not required.
The Importance of Correct Installation
No matter which system you choose, correct installation and system design are critical.
Poorly installed systems can lead to:
- Uneven airflow
- High energy bills
- Reduced lifespan
- Performance issues during extreme heat
