Ducted Split Systems – Everything You Need to Know

Ducted split systems in Melbourne are a popular choice for both residential and commercial properties, offering an efficient and versatile solution for heating and cooling. However, understanding the ins and outs of these systems can be a bit daunting, especially if you’re used to more conventional heating or cooling solutions. This guide aims to demystify ducted split systems, putting them into terms you can easily understand and helping you make an informed decision about whether they’re the right choice for your property.

What is a Ducted Split System?

A ducted split system is a type of air conditioning system that consists of an outdoor unit and an indoor unit, as well as ductwork that runs throughout your property. The outdoor unit contains the compressor and condenser, while the indoor unit houses the air handler, which includes the fan and the evaporator coil. The system works by circulating air from the indoor unit through the ductwork to various rooms in your property.

The Benefits of Ducted Split Systems

One of the main advantages of ducted split systems in Melbourne is their ability to cool or heat multiple rooms simultaneously. This is particularly beneficial for larger properties or those with open-plan designs. Many ducted split systems also offer zoning capabilities, allowing you to control the temperature in different areas of your property independently. This not only enhances comfort, but also improves energy efficiency by reducing the need to heat or cool rooms that aren’t in use.

Installation & Maintenance

The installation of a ducted split system requires professional expertise due to the complexity of the process, which can involve installing ductwork (if there isn’t existing ductwork on the premises), connecting the indoor and outdoor units and setting up the control system. However, once installed, these systems are relatively easy to maintain. Regular maintenance typically involves cleaning or replacing filters, checking for leaks in the ductwork and ensuring the outdoor unit is free from debris.

Energy Efficiency

Ducted split systems are known for their energy efficiency. They use less energy than traditional air conditioning systems, which can result in significant savings on energy bills over time. In some cases, the savings from these systems can be enough to offset the initial cost of installing the unit itself.

Cost Considerations

While the upfront cost of ducted split systems in Melbourne can be higher than other types of air conditioning systems, they can be more cost-effective in the long run due to their energy efficiency and the potential increase in property value they can offer. However, the exact cost can vary depending on several factors, such as the size of your property, the complexity of the installation and the specific model you choose.


Ducted split systems offer a versatile and efficient solution for cooling and heating. By understanding how they work and the benefits they offer, you can make an informed decision about whether they’re the right choice for your property. Consult with a professional to assess your specific needs and ensure you get the best unit for your specific use case.
