Ducted vs Split System Air Conditioning: The Complete Guide

When choosing an air conditioning / heat pump system for your home, two popular options often come up: ducted air conditioning and split system air conditioning. Both systems have their strengths and are suited to different types of homes, budgets, and lifestyle needs. We will explore what each system is, the key differences, and which might be better for your home.

What is Ducted Air Conditioning?

Ducted air conditioning systems use a central unit, typically installed in the roof space, which pushes cooled or heated air through a network of ducts to multiple rooms in the home. The airflow is distributed through ceiling or floor vents, providing seamless temperature control across the entire house. These systems can be zoned, allowing you to control different temperatures in different areas.

The brands that we affiliate with are:
• Mitsubishi Electric ducted air conditioning systems
• Fujitsu General Australia ducted system

Ducted systems are ideal for whole-home climate control and are often chosen for their discreet appearance and powerful performance.

What is Split Air Conditioning?

A split system air conditioner consists of two main components: an indoor unit that blows cooled or heated air into a single room, and an outdoor unit that expels heat from the refrigerant. These systems are perfect for individual rooms or small spaces and are easier to install.

Split systems can also be part of a multi-split setup, where several indoor units are connected to a single outdoor unit.

Difference Between Ducted and Split System

The key differences between ducted air conditioners and split system air conditioners should be considered when looking at your next heating and cooling options for your home:

1. Coverage Area
• Ducted air conditioning is designed for whole-house coverage. It cools or heats multiple rooms from a single central unit.
• Split systems are ideal for single rooms or open-plan areas.

2. Installation
• Ducted systems require roof space and professional installation. Ducting must be laid throughout the house, which can be more

complex and time-consuming.
• Split systems are easier and faster to install, requiring only a wall-mounted indoor unit and an outdoor compressor.

3. Cost
• The cost difference between ducted and split system setups is significant. Ducted air conditioning systems are more expensive

upfront, especially for large homes.
• Split systems are more budget-friendly and allow for gradual installation room-by-room.

4. Energy Efficiency
• Split systems tend to be more energy-efficient for cooling or heating individual rooms.
• Ducted systems, especially when zoned, can be efficient for larger homes, however may consume more energy if not managed

ambient setting.

5. Aesthetics and Space
• Ducted systems are virtually invisible, with only vents visible in the ceiling or floor.
• Split systems have a more noticeable presence with a wall or floor-mounted unit, which may not suit all interior designs.

Which One is Better for Your Home: Ducted or Split System?

Choosing between a duct air conditioner and a split system depends on your specific needs:

Choose Ducted Air Conditioning If:

• You want to cool or heat the entire home evenly.
• You prefer a discreet, streamlined aesthetic.
• You’re building or renovating and have the budget for a more complex system.
• You want zoning features for energy savings.
  

Choose a Split System Air Conditioner If:

• You need to heat or cool a single room or area.
• You're on a tighter budget.
• You want a quick, easy installation.

Both ducted heating and cooling systems and split systems can use reverse cycle technology, meaning they both provide ducted heating in winter and ducted cooling in summer (or the same with split systems).

There’s no one-size-fits-all answer in the air conditioning split system vs ducted debate. It comes down to the size of your home, your budget, and how much control you want over individual room temperatures.

Whether you go for a Mitsubishi Electric or Fujitsu General ducted or split system, or any other brand, make sure it fits your lifestyle and energy efficiency goals.
