The Core Benefits of Split System Air Conditioning
- Energy efficiency
- Cost savings
- Heating and cooling
- Quiet operation
- Easy installation
- Air purification
1. Energy Efficiency of Split System Air Conditioners
Split system air conditioners stand out in the HVAC market primarily due to their impressive energy efficiency. These units deliver conditioned air directly to specific areas, eliminating energy waste and significantly reducing power consumption.
The efficiency of these systems is measured using the Energy Efficiency Ratio (EER). In Australia, air conditioners must meet mandatory energy efficiency requirements.
But reverse-cycle air conditioners are generally the most energy-efficient combined heating and cooling system you can buy.
Inverter technology represents another significant advancement in split system efficiency. Traditional air conditioners operate on a simple on-off cycle, running at full capacity until the desired temperature is reached, then shutting off completely.
This repeated cycling wastes energy and creates temperature fluctuations. In contrast, inverter-equipped split systems adjust their operating speed based on real-time cooling demands.
Maintaining a consistent temperature with minimal fluctuation reduces energy consumption while providing superior comfort.
2. Cost Savings with Split System Air Conditioning
The financial benefits of split system air conditioning extend beyond energy efficiency. When compared with a ducted system, the initial investment for a split system is considerably lower.
Not only are the units themselves cheaper but installation costs for split systems are lower as well. This is generally due to simpler installation requirements and the elimination of expensive ductwork.
Multi-split systems also offer cost-saving benefits. These connect several indoor units to a single outdoor unit, offering better value than installing multiple separate systems.
Additionally, lower maintenance costs are another benefit of split systems over the long term. Without ductwork to clean, inspect or repair, routine maintenance focuses primarily on filter cleaning, coil inspection and occasional refrigerant checks.
These simpler maintenance requirements typically translate to lower service costs and less frequent professional attention.
3. Split Systems Heat and Cool
Modern split system air conditioners typically feature reverse cycle technology, transforming them from single-purpose cooling appliances into comprehensive climate control solutions. This dual functionality eliminates the need for separate heating and cooling systems, reducing equipment costs and simplifying home climate management.
The reverse cycle process works by essentially reversing the refrigeration cycle used for cooling.
- Cooling – the system extracts heat from indoor air and releases it outside.
- Heating – the system extracts heat energy from outdoor air (even in cold conditions) and transfers it indoors.
This process is remarkably efficient, often delivering 3-4 kW of heating energy for every 1 kW of electricity consumed.
The dual-purpose capability is particularly valuable in areas with both hot summers and cool winters, where seasonal climate control is essential.
The ability to switch between heating and cooling with a single system also simplifies control interfaces and reduces maintenance requirements. Many advanced models now include smart controls that automatically switch between modes based on temperature settings and current conditions, further enhancing convenience and energy efficiency.
4. Split Systems Operate Quietly
The quiet operation of split system air conditioners is a significant advantage. No one wants a loud indoor unit in their home office space, or worse, their bedroom.
Split systems reduce noise because the compressor and condenser (typically the loudest components) are placed outside. The quieter unit remains indoors, minimising disruption.
Indoor units are engineered for minimal sound production, with most operating at just 19-30 decibels on low settings. This is comparable to a whisper (20 dB) or ambient background noise (40 dB).
Advanced fan designs, vibration isolation mounts and insulated air channels that minimise turbulence help reduce noise. In contrast, window air conditioners typically produce 50-70 decibels of noise, making split systems substantially quieter.
Modern split systems include dedicated quiet or sleep modes that further reduce operating noise during sensitive periods. These modes typically limit compressor speed and fan operation to their lowest settings, prioritising quiet performance over rapid cooling.
5. Easy Installation for Split System Air Conditioning
The straightforward installation process represents one of the most practical advantages of split system air conditioning. Compared to the extensive work required for ducted systems, split system installation involves minimal disruption and structural modification.
The basic installation requires only three main connections:
- Refrigerant lines
- Electrical wiring
- Condensate drain line
Professional installers can typically complete a single-zone installation in 4-8 hours, depending on complexity. This fast installation minimises downtime and disruption, particularly important for businesses that cannot afford extended closures or households with busy schedules.
The absence of ductwork installation not only saves time but also eliminates the mess and debris associated with more invasive HVAC projects.
Here’s a quick rundown of a basic installation process:
- Mount brackets for the indoor and outdoor units
- Create a small opening in the wall for the connection lines
- Secure the indoor and outdoor units
- Connect the refrigerant lines
- Evacuate any air from the system
- Test for leaks before charging the system with the refrigerant
- Connect electrical components and test the system for proper operation
Professional Installation
While the installation process is simpler than for ducted systems, professional installation remains essential. Proper installation directly impacts system efficiency, performance and lifespan.
And installing air conditioning without appropriate qualifications and training is illegal.
Benefits a professional technician offers:
- Correct sizing based on room dimensions and heat load calculations
- Strategic placement of indoor and outdoor units for optimal airflow and efficiency
- Proper evacuation and charging of the refrigerant system
- Secure mounting to prevent vibration and noise
- Proper sloping of drain lines to prevent water damage
Professional installers also ensure compliance with local building codes and manufacturer specifications, which helps maintain warranty coverage and system longevity.
6. Air Purification Features
Modern split system air conditioners offer significant air quality benefits through integrated filtration and purification features. These vastly improve indoor air quality.
Split systems like the Daikin Alira X are integrated with Streamer Technology. These systems come in various sizes to suit different needs:
- Daikin Alira X 2.2KW
- Daikin Alira X 2.5KW
- Daikin Alira X 3.5KW
- Daikin Alira X 4.6KW
- Daikin Alira X 5.0KW
- Daikin Alira X 6.0KW
- Daikin Alira X 7.1KW
The cutting-edge Streamer Technology works on a powerful oxidative decomposition process to remove odours, bacteria, and harmful substances from the air.
Air purification is vital for people with:
- Asthma
- Hay fever
- Other allergies
Australia has high rates of asthma and allergies, making this benefit important when choosing an air conditioner. Such features improve air quality inside your home and contribute to a healthier indoor environment.
What is Split System Air Conditioning?
Split system air conditioning is a popular and energy-efficient way to cool or heat individual rooms or spaces in Australian homes and businesses. It’s called a “split” system because it has two main parts:
- An indoor unit – usually mounted high on a wall inside the room. This unit blows cool or warm air into the corresponding room.
- An outdoor unit – sits outside the building and contains the compressor that either removes heat (in cooling mode) or brings in heat (in heating mode).
These two units are connected by a set of refrigerant pipes and electrical cables, allowing them to work together to control the indoor climate.
Most split systems in Australia are reverse-cycle units. This means they provide both cooling and heating, making them ideal for year-round comfort.
Best Use Cases for Split System Air Conditioners
Split system air conditioners excel in specific scenarios where traditional ducted systems or window units fall short.
Apartments and Single-Room Installations
Apartments present unique cooling challenges due to limited space, structural restrictions and building regulations. Split systems offer an ideal solution for these environments.
Their compact indoor units can be mounted high on walls, requiring minimal floor space while providing direct, efficient cooling. The absence of ductwork makes them perfect for retrofitting into existing structures without major renovations.
Single-room applications like home offices, bedrooms or sun rooms that may get disproportionately warm are also ideal for split systems. This is because split systems allow for targeted cooling in specific spaces.
Homes Where Ducted Systems Aren’t Practical
While ducted air conditioning is a great solution for cooling or heating an entire home, it’s not always the best fit. This is especially true for areas with limited space and often older homes.
Ducted systems require significant space in the ceiling or under the floor to run ductwork. Installing ducts may be impossible or extremely expensive in homes with:
- Flat roofing
- Low roof cavities
- Multi-storey layouts with no ceiling access
Split systems don’t need ducts, making them ideal for these setups.
In older homes or buildings with solid brick walls and no cavity space, running ductwork can be highly invasive and costly. A split system can be installed with minimal disruption and doesn’t require major structural changes.
Energy-Conscious Homeowners Seeking Temperature Control
For homeowners focused on energy efficiency, split systems offer compelling advantages. Reverse-cycle split system air conditioners are generally the most energy-efficient combined heating and cooling system you can buy.
Modern split systems feature inverter technology that continuously adjusts compressor speed rather than cycling on and off. This maintains more consistent temperatures while consuming less electricity.
Many new models also incorporate smart controls that allow programming and remote operation via smartphone apps. This helps you optimise energy use based on occupancy patterns and preferences.
