Split System Vs Ducted Air Conditioning: Which Suits Your Home?

Split system air conditioning is one of the most widely used options in Australian homes. It consists of an indoor unit mounted on a wall and an outdoor compressor connected by refrigerant piping.

Each split system cools a specific area or room. The indoor unit draws in warm air, cools it, and circulates it back into the space, while heat is expelled outside through the outdoor unit.

Split systems are commonly installed in:

• Bedrooms
• Living rooms
• Home offices
• Smaller homes or units
• Extensions or renovated rooms

Because they cool individual zones, split systems offer flexibility and targeted temperature control.

Split systems are popular for several practical reasons.

Compared to ducted systems, split systems usually have a lower upfront cost. This makes them appealing for homeowners upgrading gradually or working within a renovation budget.

Each unit operates independently, allowing you to cool only the rooms you’re using. This can suit households with varying schedules or limited cooling needs.

Split systems can often be installed with minimal structural changes, particularly in existing homes.

For apartments, townhouses or homes with a small number of frequently used rooms, split systems can provide sufficient cooling without unnecessary complexity.

While split systems offer flexibility, there are a few factors to keep in mind.

• Multiple units may be required for whole-home coverage
• Wall-mounted units are visible inside rooms
• Outdoor space is needed for each compressor
• Cooling large, open-plan areas may require larger units

For some homeowners, these considerations influence the decision to explore ducted systems instead.

Ducted air conditioning provides whole-home cooling through a network of ducts installed in the ceiling or roof space. A central unit distributes cool air to multiple rooms via vents.

Air is cooled at a central unit and delivered through ducts to each room. Zones can be created so specific areas of the home are cooled independently.

Ducted systems are often chosen for:

• New builds
• Larger homes
• Open-plan layouts
• Homes undergoing major renovations
• Households wanting discreet cooling

Because all components are hidden, ducted systems offer a streamlined appearance.

Ducted air conditioning appeals to homeowners seeking consistent comfort throughout the home.

A single system can cool every room, making it ideal for families or homes where multiple spaces are used regularly.

With only vents visible, ducted systems preserve interior design and avoid wall-mounted units.

Zoning allows different areas to be cooled as needed, offering flexibility for bedrooms, living spaces and rarely used rooms.

Ducted systems provide even airflow and temperature distribution, which can be particularly beneficial in open-plan homes.

Ducted air conditioning also comes with factors to consider.

• Higher upfront installation cost
• Requires sufficient roof or ceiling space
• Installation is easier during construction or major renovation
• May be more than required for smaller homes

Understanding these aspects helps homeowners weigh long-term comfort against initial investment.

Townsville’s climate plays a key role in deciding which system suits your home best.

In hot, humid conditions, many households rely on air conditioning daily. Homes that require cooling in multiple rooms at once often benefit from ducted systems, while those using one or two key areas may find split systems sufficient.

• Smaller homes or units often suit split systems
• Large or open-plan homes often suit ducted systems
• Homes with multiple levels may benefit from ducted zoning

Renovations vs New Builds

Split systems are often easier to add to existing homes. Ducted systems are commonly chosen for new builds or major renovations where access and planning are simpler.

Energy efficiency depends on how the system is used rather than the system type alone.

Because they cool individual rooms, split systems can be efficient when used selectively. Cooling only occupied spaces may reduce overall energy use.

Modern ducted systems with zoning can be managed efficiently by cooling only selected areas. However, running the entire system continuously may increase energy use if not managed carefully.

Choosing the right system size and using zoning effectively supports better energy management for air conditioning in Townsville.

Your daily routine and household habits also influence which system feels more suitable.

Split systems may suit households that:

• Use only a few rooms regularly
• Have staggered schedules
• Prefer incremental upgrades

Ducted systems may suit households that:

• Use multiple rooms throughout the day
• Prefer consistent temperature across the home
• Value minimal visual impact

There’s no one-size-fits-all answer — lifestyle often plays a deciding role.

When deciding between split and ducted air conditioning, it’s worth considering long-term plans.

Questions to ask include:

• Will household size change?
• Are future renovations planned?
• Will additional rooms be added later?
• How long do you plan to stay in the home?

Thinking ahead can help ensure your chosen system continues to meet your needs over time.

Selecting the right system involves more than comparing prices. Factors such as system sizing, placement, airflow and zoning all influence comfort and performance.

When searching for air conditioning, working with a local provider familiar with Townsville conditions can help tailor recommendations to your home’s layout and climate demands.

Split system and ducted air conditioning both offer reliable cooling solutions — the key is matching the system to your home and lifestyle.
