Ducted vs Split System Air Conditioning: Which is Best?
Choosing the right air conditioning system for your home is a significant decision. Both ducted and split systems offer effective cooling and heating solutions, but they differ considerably in installation, cost, efficiency, and overall suitability. This article provides a detailed comparison to help you make an informed choice.
Installation Costs and Requirements
One of the most significant differences between ducted and split systems lies in their installation process and associated costs.
Ducted Air Conditioning
Higher Upfront Costs: Ducted systems typically have a higher initial installation cost. This is due to the complexity of the installation process, which involves installing ductwork within the ceiling or floor spaces.
Extensive Ductwork: The installation requires careful planning and execution to ensure efficient airflow throughout the house. This includes designing the duct layout, installing vents in each room, and connecting the ductwork to the central unit.
Professional Installation: Due to the complexity, professional installation is essential. This adds to the overall cost but ensures the system operates efficiently and safely.
Structural Considerations: Existing homes may require modifications to accommodate the ductwork, which can further increase costs. New builds can integrate ductwork more seamlessly during construction.
Split System Air Conditioning
Lower Initial Costs: Split systems generally have a lower upfront cost compared to ducted systems. This is because the installation is simpler and requires less extensive work.
Individual Units: Each split system consists of an indoor unit and an outdoor unit connected by refrigerant lines and electrical wiring.
Easier Installation: Installation typically involves mounting the indoor unit on a wall and placing the outdoor unit on a concrete slab or mounting bracket. A qualified technician is still recommended for proper installation and refrigerant handling.
Less Structural Impact: Split systems have minimal impact on the existing structure of the home, making them a more convenient option for retrofitting.
Energy Efficiency and Running Costs
Energy efficiency is a crucial factor to consider, as it directly impacts your running costs and environmental footprint.
Ducted Air Conditioning
Potential for High Efficiency: Modern ducted systems can be highly energy-efficient, especially those with inverter technology. Inverter systems adjust the compressor speed to match the cooling demand, resulting in lower energy consumption.
Zoning Capabilities: Ducted systems can be zoned, allowing you to control the temperature in different areas of the house. This can save energy by only cooling or heating occupied zones. Learn more about zoning options.
Ductwork Losses: Inefficiently insulated or poorly designed ductwork can lead to energy losses, reducing the overall efficiency of the system. Regular maintenance and sealing of ducts are essential to minimise these losses.
Split System Air Conditioning
High Star Ratings: Split systems often boast high energy star ratings, indicating their efficiency. Look for models with a high Coefficient of Performance (COP) for heating and Energy Efficiency Ratio (EER) for cooling.
Individual Control: Each split system unit can be controlled independently, allowing you to only cool or heat the rooms you are using. This can be more energy-efficient than running a ducted system to cool the entire house when only a few rooms are occupied.
No Ductwork Losses: Since split systems don't rely on ductwork, there are no energy losses associated with duct leakage or poor insulation.
Coverage and Zoning Options
Coverage refers to the area that the air conditioning system can effectively cool or heat, while zoning allows you to control the temperature in different areas independently.
Ducted Air Conditioning
Whole-House Coverage: Ducted systems are designed to provide consistent temperature throughout the entire house.
Zoning Advantages: Zoning allows you to divide your home into different temperature zones, such as living areas, bedrooms, and home office. This enables you to customise the temperature in each zone to suit your preferences and needs.
Centralised Control: A central thermostat controls the entire system, making it easy to manage the temperature throughout the house.
Split System Air Conditioning
Room-by-Room Coverage: Split systems provide cooling or heating for individual rooms or areas. To cool an entire house, you would need to install multiple split system units.
Individual Control: Each split system unit has its own remote control, allowing you to adjust the temperature and fan speed independently.
Limited Zoning: While you can control the temperature in each room with a split system, it doesn't offer the same level of centralised zoning control as a ducted system. However, you can choose to only run the units in occupied rooms, effectively creating a form of zoning.
Aesthetics and Noise Levels
The appearance of the air conditioning system and its noise levels can impact the comfort and aesthetics of your home.
Ducted Air Conditioning
Discreet Appearance: Ducted systems are generally more discreet, as the ductwork is hidden within the ceiling or floor spaces. Only the vents are visible in each room.
Quieter Operation: The central unit is typically located outside the living area, resulting in quieter operation compared to split systems.
Consistent Airflow: Ducted systems provide a consistent and even airflow throughout the house, creating a more comfortable environment.
Split System Air Conditioning
Visible Units: Split systems have visible indoor units mounted on the wall, which may not appeal to everyone's aesthetic preferences.
Potentially Noisier: The indoor unit can generate some noise, although modern split systems are designed to operate quietly. The outdoor unit also produces noise, but it is typically located outside the house.
Direct Airflow: Split systems provide direct airflow to the area in front of the unit, which may not be as comfortable as the consistent airflow of a ducted system.
Maintenance and Servicing
Regular maintenance and servicing are essential to ensure the efficient and reliable operation of your air conditioning system.
Ducted Air Conditioning
Professional Servicing: Ducted systems require professional servicing to clean the ductwork, check for leaks, and inspect the central unit. This should be done at least once a year.
Filter Replacement: Regularly replacing the air filters is crucial to maintain good air quality and prevent dust and debris from accumulating in the system.
Duct Cleaning: Over time, dust and allergens can accumulate in the ductwork, requiring professional cleaning to maintain a healthy indoor environment. Newappliances offers services to help with maintaining your system.
Split System Air Conditioning
DIY Maintenance: Split systems are relatively easy to maintain. You can clean the air filters yourself and wipe down the indoor unit.
Professional Servicing: Professional servicing is still recommended to check the refrigerant levels, clean the coils, and inspect the overall system. This should be done every two to three years.
Coil Cleaning: The coils of the indoor and outdoor units can accumulate dust and debris, reducing their efficiency. Professional cleaning can help restore their performance.
Overall Suitability for Different Homes
Choosing between ducted and split systems depends on your specific needs, budget, and the characteristics of your home.
Ducted Systems: Are generally better suited for larger homes or those where consistent temperature throughout the entire house is desired. They are also a good option for new builds where ductwork can be easily integrated into the design. Consider the initial investment and ongoing maintenance costs. When choosing a provider, consider what Newappliances offers and how it aligns with your needs.
Split Systems: Are a more cost-effective option for smaller homes or apartments where individual room control is preferred. They are also a good choice for retrofitting existing homes, as they require less extensive installation work. Split systems offer flexibility and energy efficiency, making them a popular choice for many homeowners.
Ultimately, the best choice depends on your individual circumstances. Carefully consider the factors outlined in this article to make an informed decision that meets your needs and budget.
