Understanding The Basics Of Both Systems

Ducted and split system air conditioning units serve the same primary purpose: to cool or heat spaces. However, their mechanisms and applications are different. Ducted systems circulate air through ducts in ceilings or under floors, providing a uniform temperature throughout the space. In contrast, split systems consist of an indoor unit connected to an outdoor compressor that controls temperature in designated areas. 

Assessing The Space: Which System Fits Best?

  • Size of the area: Larger spaces might benefit more from ducted systems due to their capacity to cool or heat areas uniformly. 
  • Layout: Open-plan spaces can be efficiently managed with ducted systems, while split systems can be ideal for spaces with multiple rooms or levels.

Energy Efficiency And Consumption

When it comes to energy efficiency, the type of air conditioning system you choose plays an important role. Ducted air conditioning systems help maintain a consistent temperature throughout, which can be more energy-intensive, especially if the entire area doesn’t require cooling or heating at the same time. On the other hand, split systems are often the ideal choice for smaller areas or individual rooms. Their design and functionality make them more energy-efficient for such spaces, which can lead to savings in the long run. 

Installation Process And Requirements

Installing ducted air conditioning systems is more complex, often requiring significant alterations, especially in existing structures. Conversely, split systems are simpler to install, usually quicker and need fewer structural adjustments. 

Maintenance And Longevity

  • Ducted Systems: Require regular cleaning of ducts to ensure optimal performance and air quality. 
  • Split Systems: Maintenance primarily involves cleaning or replacing filters and ensuring the outdoor unit is free from obstructions.

Cost Implications: Initial And Ongoing

  • Initial Costs: Ducted systems have a higher upfront cost due to the extensive installation process. Split systems, with fewer components, tend to be more affordable initially. 
  • Ongoing Costs: Ducted systems may cost more to maintain, but with proper care, they can last longer, balancing out the expenses.
