Frequently Asked Questions About Ducted Split Systems

Ducted split systems have been gaining popularity as an efficient alternative to traditional heating and cooling solutions. Particularly, homeowners in Melbourne have been opting for ducted split systems due to their energy efficiency and the flexibility they offer in climate control throughout different zones of a property. Here are some frequently asked questions about ducted split systems in Melbourne that can help you understand why they might be the right choice for your home or business.

What is a Ducted Split System?

A ducted split system consists of an outdoor unit and one or more indoor units that work together to heat or cool a space with the help of a network of ducts. Each indoor unit can be controlled independently, offering personalised temperature settings in different rooms.

How Are Ducted Split Systems Installed?

The installation of ducted split systems in Melbourne typically involves mounting the indoor units on interior walls and connecting them to the outdoor unit via a small conduit. The conduit houses the power cable, refrigerant tubing, suction tubing and a condensate drain. Ductwork is then installed so that air can be circulated throughout the building. 

Are Ducted Split Systems Energy-Efficient?

Yes, ducted split systems are known for their energy efficiency. The zoned climate control means that you only need to heat or cool the spaces that you’re using, thus reducing wastage of energy.

Can Ducted Split Systems Provide Both Heating & Cooling?

Yes, ducted split systems can provide both heating and cooling. Many models are equipped with a heat pump function, allowing them to reverse the refrigeration cycle and produce heat during the cooler months. This dual functionality makes ducted split systems in Melbourne an attractive option for all-year-round comfort.

What Sort of Maintenance Do Ducted Split Systems Require?

Like any heating and cooling system, ducted split systems require regular maintenance to operate efficiently and prevent breakdowns. On the indoor units, filters should be cleaned or replaced as per the manufacturer’s instructions. The outdoor unit should be kept clear of debris to ensure adequate airflow. Annual professional servicing is also recommended to check the system’s refrigerant levels and ensure all components are functioning correctly.

Are Ducted Split Systems Cost-Effective?

Initially, the installation of a ducted split system might be more expensive compared to traditional HVAC systems due to the costs of the units and the labour involved. However, the long-term savings on energy bills can offset this initial outlay. Additionally, because ducted systems allow for zone-specific climate control, users can save money by only heating or cooling rooms that are occupied.


Ducted split systems in Melbourne represent a versatile, energy-efficient and cost-effective solution for personalised climate control. Whether you’re looking to retrofit your house or you’re planning a new construction, ducted split systems offer both flexibility and performance that are hard to match with conventional HVAC options. Remember, proper maintenance and choosing the right system size will optimise the benefits of a ducted split system for your home or business.
