Choosing between ducted heating and split systems for your Melbourne home involves weighing up costs, efficiency, and comfort. We’ll break down the key factors to help you decide which system best suits your needs and living space.
Initial Installation Costs
Ducted heating tends to have higher initial installation costs due to the extensive ductwork required, which can be complex to fit into existing homes. Split systems, on the other hand, are generally more affordable to install, especially if you only need to cool or heat a few rooms.

Ongoing Running Costs
While both systems are efficient, their running costs can vary. Ducted heating systems spread warmth throughout the entire home, potentially leading to higher energy bills if you don’t need to heat every room. Split systems allow for more precise temperature control, which can help you save on energy costs by targeting specific areas.
Cleaning and Maintenance
Ducted heating systems require regular duct cleaning to maintain air quality and efficiency. Over time, dust and debris can accumulate in the ducts, reducing the system’s performance and potentially causing allergies or respiratory issues. Split systems are generally easier to clean and maintain, as they don’t have extensive ductwork.

Noise Levels
Noise can be a significant factor when choosing between ducted heating and split systems. Ducted systems are typically quieter, as the central unit is usually located outside or in a designated area within the home. Split systems can be noisier, particularly the outdoor unit, which may cause disturbances if placed near living areas or bedrooms.
Choosing the Right System

Ducted Heating Benefits
- Even heating throughout the home
- Centralised control for the entire property
- Includes reversible air conditioning in many cases (refrigerated ducted systems)
- Quiet operation for better ambient noise levels
- Multiple temperature zones available (premium ducted systems with zoning)
- Can streamline wall design, as vents and outlets are smaller and specifically placed to keep aesthetics clean
- More suitable for larger homes as connected rooms are easier to heat or cool
Split System Advantages
- Lower initial cost
- Faster, less invasive installation as no air ducts are required
- More flexible zoning and temperature targeting
- Individual room units mean no heat buildup when idling, only as you need it
- Individual split units can be replaced or upgraded individually (no need to replace the whole system)
- More modern design with sleek aesthetics and less wall clutter
- More suitable for smaller homes or single-room applications
- Precise cooling, particularly important for Melbourne’s warmer seasons
Making the Decision
Ultimately, the choice between ducted heating and split systems depends on your specific needs and preferences. If you prioritise even heating, centralised control, and are willing to invest in higher initial costs, ducted heating might be the best option. On the other hand, if you prefer lower upfront costs, easier maintenance, and the ability to control temperatures in individual rooms, split systems could be more suitable.
