Multi Head Split Systems

What is a Multi Head Split System Air Conditioner?

A multi head split system air conditioner consists of a single outdoor unit connected to multiple indoor units. While a traditional split system air conditioner includes one outdoor unit and one indoor unit, a multi head split system can include five or more indoor units, depending on the capacity of the system you choose. This allows each indoor unit to be independently controlled

Benefits of a Multi Head Split System Air Conditioner

  1. Individual Temperature Control: With a multi head split system, you have the flexibility to set different temperatures in each room or area. This allows for personalised comfort preferences, accommodating the varying conditioning needs of different occupants or zones within your home or building.
  2. Cost Effective Solution: Compared to installing separate air conditioners in each room or area, a multi head split system can be a cost effective solution. It eliminates the need for multiple outdoor units, reducing installation and maintenance costs.
  3. Space Saving: A multi head split system requires only one outdoor unit which can save space compared to having multiple outdoor units. This is especially beneficial in situations where outdoor space is limited or aesthetically important.
  4. Energy Efficiency: Multi head split systems often incorporate advanced technologies, such as inverter compressors, which optimise energy consumption. Each indoor unit can be individually controlled allowing you to only condition the areas that are in use. This zoning capability helps minimise energy waste and contributes to overall energy efficiency.
  5. Quiet Operation: The outdoor unit of a multi head split system contains the compressor and other noise producing components. As a result, the indoor units operate quietly providing a peaceful and comfortable indoor environment.
  6. Customisable Configuration: Multi head split systems offer flexibility in terms of configuration. You can choose different types and capacities of indoor units based on the specific cooling requirements of each room or area. This allows for a tailored and optimised solution to meet your needs.
  7. Easy Installation: Installing a multi head split system is generally less complex and time consuming compared to traditional ducted systems. The indoor units are connected to the outdoor unit through refrigerant lines and electrical wiring, without the need for extensive ductwork. This simplifies the installation process and reduces disruption to your home or building.
  8. Aesthetically Pleasing: The indoor units of a multi head split system are typically compact and sleek in design, and are available in various styles to blend seamlessly with your interior decor. They can be mounted on walls, suspended from ceilings, or recessed into the ceiling, providing a clean and unobtrusive lo

Multi Head Split System vs. Individual Split System

The key difference between these two types of air conditioning systems lies in the number of indoor units that a single outdoor unit can accommodate. A multi head split system includes a solitary outdoor unit linked to several indoor units. In contrast, a conventional split system air conditioner features a single outdoor unit paired with a single indoor unit.


Multi head split systems can accommodate five or more indoor units, depending on what system capacity you choose. While uncommon, it is worth noting that a multi head split system may not be able to run all indoor units at their maximum capacity simultaneously. The overall system’s efficiency decreases as the outdoor unit’s size, relative to all of the combined indoor units, tends to not be large enough. In cases like this, installing separate split systems would allow each unit to operate at its full capacity.

Multi Head Split System vs. Ducted Air Conditioning

Ducted air conditioning excels at quickly providing comprehensive cooling and heating for an entire home or building. In contrast to a multi head split system, you won’t need to individually adjust each room’s air conditioning – it can be controlled through a single unit. Due to their advanced zoning and control options, ducted systems are able to be customised to suit the specific needs of everyone in the house, but do come at a higher price point. 

Multi head split systems are a more affordable solution and are particularly suitable for those facing space constraints, such as limited ceiling or floor space, which may not be conducive for a ducted system installation.

Multi Head Split System Maintenance

Regular maintenance is crucial for your multi head split system to ensure optimal performance. It is recommended to schedule an annual service performed by a certified air conditioning technician to guarantee your system’s efficiency and safety, thereby extending its lifespan.

Each indoor unit of a multi head split system features filters that require periodic cleaning, typically every 3-6 months depending on usage frequency. Cleaning these filters is a straightforward task that you can tackle on your own if you have the necessary knowledge. Alternatively, if you prefer, a qualified air conditioning technician can handle this maintenance for you.
