Ducted Air Conditioning

Ducted air conditioners are centrally controlled systems designed to cool or heat an entire building through a network of ducts. These systems can be particularly advantageous for maintaining a consistent temperature throughout a home.

Benefits of Ducted Air Conditioning

  • Whole-Home Cooling: A major benefit of ducted systems is their ability to cool the entire house using a single unit. The main unit cools the air, which is then distributed throughout the home via ducts, maintaining a consistent temperature in every room. This can also help preserve the condition of your home’s interiors, including flooring and furniture.
  • Aesthetic and Quiet: Because the main unit is located out of sight, usually in the roof space, the only visible components are the discreet vents. This design makes ducted systems more visually appealing and quieter compared to split systems, which have visible and potentially noisy indoor units.
  • Zoning Capability: Many ducted systems come with zoning options, allowing you to cool or heat different areas of your home individually. This feature can significantly improve energy efficiency and reduce running costs, as you can target only the areas in use rather than cooling the entire house.
  • Set and Forget: With a central control unit, often wall-mounted, you can set your desired temperature for the entire house, and the system will maintain it automatically, providing a hassle-free experience.

Drawbacks of Ducted Air Conditioning

  • Running Costs: Without zoning, ducted systems can be expensive to run as they cool the entire house even if only one room is in use. However, with proper zoning, these costs can be managed more effectively.
  • High Upfront Costs: Ducted air conditioning systems are generally more expensive to purchase and install compared to split systems, as they require extensive ductwork and multiple vents throughout the home.
  • Space Requirements: Ducted systems need significant space for ducts and the main unit, usually in the roof. Homes without sufficient roof space may not be suitable for ducted systems.
  • Fixed Control: The control unit is typically fixed in one location, meaning you have to go to that spot to adjust settings. Some modern systems offer smartphone compatibility, providing more flexibility.

Split System Air Conditioning

Split system air conditioners consist of an indoor unit and an outdoor unit, designed to cool or heat individual rooms or areas. These systems are versatile and can be a good choice for cooling specific spaces within your home.

Benefits of Split System Air Conditioning

  • Lower Upfront Cost: Split systems are generally cheaper to purchase and install compared to ducted systems. They require minimal installation, which also means a shorter setup time.
  • Cost Spread: You can spread the cost of cooling your entire home by gradually adding more split systems over time, instead of a large upfront investment required for a ducted system.
  • Suitable for Multi-Level Homes: Split systems can be installed in multi-level homes and apartments where ducting might not be feasible.
  • Lower Running Costs: Since split systems only cool specific areas as needed rather than the entire house, their running costs can be lower than ducted systems, especially when used efficiently.
  • Ease of Repair: Split systems are generally easier and cheaper to repair. If one unit fails, the rest of your home can still remain cool.

Drawbacks of Split System Air Conditioning

  • Noise: The indoor units of split systems can produce noise, which may be disruptive. Additionally, the outdoor units can be noisy, potentially disturbing neighbours.
  • Aesthetic Impact: Indoor units are mounted on walls, which can be visually obtrusive. The outdoor unit’s placement can also affect the exterior appearance of your home.
  • Energy Usage: For larger homes, using multiple split systems can result in higher energy usage compared to a single ducted system, particularly if each unit is not used efficiently.
  • Limited Cooling Power: Split systems are designed to cool specific areas. Larger spaces or homes with many rooms may require multiple units, potentially increasing both costs and energy consumption.

Ducted Systems are Cheaper When Compared To Having a Split System In Each Room

Ducted air conditioning systems are generally cheaper to run compared to having a split system in each room, particularly in the following scenarios:

  1. Large Spaces: In large homes or buildings with multiple rooms, ducted systems benefit from economies of scale, cooling or heating the entire space more efficiently than multiple split systems.
  2. Centralized Control and Zoning: Ducted systems with zoning capabilities allow for precise temperature control in different areas, reducing energy use by cooling or heating only the necessary spaces.
  3. Advanced Technology: Modern ducted systems often incorporate energy-efficient technologies like inverter technology, which can reduce running costs compared to multiple split systems.
  4. Installation and Maintenance: Installing and maintaining a single ducted system can be less expensive and less disruptive than managing multiple split systems.

Overall, ducted systems can provide more efficient and cost-effective climate control in larger or multi-room environments compared to having individual split systems in each room.

Split Systems Are Generally Cheaper To Run Than Ducted Systems When

Split system air conditioners are generally cheaper to run than ducted systems in the following scenarios:

  1. Small Spaces or Single Rooms: In smaller homes, apartments, or when only one or two rooms need cooling or heating, split systems are more efficient and cost-effective.
  2. Targeted Use: If you only need to cool or heat specific areas at different times, split systems allow for precise control, reducing energy consumption compared to cooling or heating the entire home with a ducted system.
  3. Lower Initial Costs: Split systems have lower installation costs compared to ducted systems, making them more economical for smaller installations.
  4. Less Complex Installation: Split systems require less invasive installation, which can be cheaper and quicker than installing a ducted system, especially in older homes not designed for ducted systems.
