As Australia’s climate swings between hot summers and cool winters, choosing the right air conditioning system is crucial for comfort and energy efficiency. Homeowners are often caught in the debate between ducted and split systems. Both options offer unique benefits, but how do you know which is the best choice for your household?

In this guide, we’ll break down the differences between ducted and split systems, exploring their features, costs, installation processes, and which type is best suited for different homes and lifestyles.

What is a Ducted Air Conditioning System?

A ducted air conditioning system cools or heats your entire home through a series of ducts installed in your ceiling or floor. The system is controlled from a central unit, distributing air evenly across various rooms.

Pros of Ducted Systems:

  • Whole-home climate control: Cool or heat multiple rooms simultaneously.
  • Discreet design: The system is concealed, with only small vents visible.
  • Zoning capabilities: Allows for custom temperature control in different areas of the home.

 

Cons of Ducted Systems:

  • Higher upfront cost: Ducted systems typically have a more significant installation cost.
  • More involved installation process: Installation can be more complex and may require some modifications to the home.

What is a Split System Air Conditioner?

A split system is made up of two units: an indoor unit that blows cool or warm air into the room and an outdoor unit that expels the heat from inside. These systems are ideal for cooling or heating individual rooms.

Pros of Split Systems:

  • Affordable: Lower upfront costs compared to ducted systems.
  • Energy efficient for smaller spaces: Great for cooling or heating specific rooms.
  • Easy installation: Installation is generally simpler and faster.

 

Cons of Split Systems:

  • Limited to one room: You may need multiple units to cool or heat your entire home.
  • Visible indoor unit: The indoor unit is mounted on the wall, which may not appeal to everyone’s aesthetic.

Which System is Right for You?

Your choice between a ducted and split system largely depends on your home’s size, your budget, and your personal preferences.

  • Ducted systems are ideal for large homes, families who want whole-home climate control, or anyone building a new house or renovating. While the upfront cost is higher, the convenience of controlling multiple rooms makes it worth the investment for many.
  • Split systems, on the other hand, are perfect for smaller homes, apartments, or people looking to cool or heat only certain rooms. They’re also more budget-friendly and can be installed with minimal disruption to your home.
