Multi Split Air Conditioning Systems
What are Multi Split Air Conditioning Systems?
Multi-split air conditioning is a system which connects multiple indoor units to one outdoor unit, so you can control the temperature in various rooms independently and have different styles and capacities combined in one system. They are similar to a Single Split System but, because they have a single outdoor unit, they are incredibly useful in situations where you have limited outdoor space for mounting condenser units.
With a multi-split system, you have complete control over the environment in each room. They can connect up to six indoor units to one outdoor without the need for duct work, such as where space in the roof or under floors is limited.

Benefits of Multi Split Systems
Space-saving design
Instead of installing multiple outdoor units, a multi-split system only requires one. This frees up exterior space and makes them a versatile option for smaller spaces.
Energy efficiency
Multi-split air conditioning systems are incredibly energy efficient, with several interior units connected to a single outdoor device. These systems are designed to be quick and easy to install, cost-effective to run and operate quietly for minimal disturbance.
Zonal climate control
Each of the units connected to the multi-split system can be operated independently for complete control in each room of your property. Users can control the temperature, air movement, timer settings and directionality of the system for each of the units, and even have different units and capacities connected, for personalised climate control that’s tailored to the environment it’s in.
Flexible installation options
The extensive piping runs for multi-split air conditioning systems make them ideally suited for larger structures and multi-storey buildings. They’re incredibly versatile and offer flexibility when it comes to installations for complex areas.
How Multi Split Systems Work
A typical multi-split system consists of an outdoor unit connected to multiple indoor units via refrigerant lines. The refrigerant absorbs heat and changes into a gas, which travels through the refrigerant lines to the outdoor unit. There, it is condensed back into a liquid, releasing the captured heat into the outside air. The cooled liquid refrigerant then makes its way back to the indoor unit where it absorbs heat again, cools the surrounding air using another heat exchanger, and finally blows cool air into the room.
The outdoor unit houses the compressor and condenser, while the indoor units contain evaporators and air handlers which distribute the air. This setup allows for independent control of each indoor unit, enabling users to adjust temperature settings in individual rooms or zones as needed. The system’s individual control mechanisms ensure efficient operation by modulating capacity based on demand.

Ideal Applications for Multi Split Systems
-
Multi Split Systems are well-suited for a range of environments, such as office spaces where different areas or rooms may have individual temperature requirements. They’re also ideal for retail environments, allowing for comfortable shopping experiences throughout the store.
In residential settings, these systems excel in multi-room setups, providing personalised comfort for different family members. Small to medium-sized businesses can also benefit from the scalability and efficiency of multi-split systems, adapting to changing space utilisation needs as needed.

Comparing Multi Split vs. Single Split Systems
-
There are several differences to consider when choosing between a multi-split and single-split system. First, the capacity – multi-split systems generally offer higher overall capacity and can accommodate more extensive spaces compared to a single-split system.
Installation costs are often higher for a multi-split system, but they are also more cost-effective long-term, especially for larger, multi-zone areas. A significant advantage of multi-split systems over single-split is the low space requirements for the outdoor units, making them perfect for properties with limited outdoor space.

Choosing the Right Multi Split System
-
When choosing a multi-split air conditioning system, you need to consider several factors including the size and layout of the property, and your specific cooling requirements. First, assess the number of indoor units you need which will typically be determined by the number of rooms or zones you want to control the temperature in.
Next, consider the capacity of the units. The combined capacity of all indoor units should match the capacity of the outdoor unit, so the system runs efficiently. Lastly, make sure you choose the right models for the room, based on its size and layout, but also aesthetic preferences.

What does the installation process involve?
-
The installation of a multi-split system begins with a thorough site evaluation to determine the best locations for the indoor and outdoor units. This is followed by the system design, taking into account factors such as refrigerant line routing, drainage and electrical requirements.
Our professional installers will then mount the outdoor unit in the agreed location, install all indoor units, connect the refrigerant lines, and set up the electrical and control systems. Proper installation is critical for the efficiency and longevity of the system – our skilled engineers will ensure you understand how to use the system comfortably and provide any after-care advice to keep the system running smoothly.

Maintenance and Care
-
Regular maintenance is essential for keeping the system operating at peak efficiency. This includes cleaning or replacing air filters regularly, checking refrigerant levels and keeping the outside unit free from dirt and debris. Make sure that there’s plenty of air flow for the outside unit, keeping bins and garden furniture out of the way of the unit, and similarly make sure there’s plenty of space around indoor units to minimise dust entering the system.
Troubleshooting common issues, such as uneven cooling or unusual noises, can also help prevent more serious problems from developing. Often these problems can be resolved by replacing the air filters or checking the thermostat is set to the minimum temperature.
In instances where refrigerant leaks or mould has developed in the system, a professional deep clean can help. By following manufacturer guidelines and scheduling professional servicing once a year, you can significantly extend the lifespan of your system and ensure consistent performance.

Energy Efficiency and Cost Savings
-
Multi-split systems are known for their high energy efficiency and are often measured by Seasonal Energy Efficiency Ratio (SEER) ratings. The SEER rating divides the average heating or cooling output of the system by the average energy consumed in Watts per hour over the cooling season.
Higher SEER ratings indicate greater efficiency and potential for energy savings. Most HVAC systems have SEER ratings ranging from 13 to 23, but multi-split systems are typically higher and can reach SEER ratings as high as 30+ depending on the system and model.
While the initial investment may be slightly higher compared to traditional systems, the long-term economic benefits of reduced energy consumption can be substantial. Additionally, the improved efficiency of these systems contributes to a lower environmental impact, making them an eco-friendly choice for climate control for homes and businesses alike.
