Multi Split Heat Pumps & Air Conditioners

A multi split system air conditioning system offers more flexibility and performance than a single room system. Fujitsu multi room heat pump / air conditioning units consist of up to five indoor units that distribute cool air throughout the space in summer, and an outdoor unit that draws heat out of the room.

A heat pump for multiple rooms is a flexible, efficient and effective method of heating or cooling your home. They provide numerous benefits over single room and even ducted heat pump / air conditioning solutions, including:

• Simple installation: Multi split heat pump / air conditioner does not require ducts for installation, lowering the cost and complexity of installation. 

• Cost effectiveness: Multi room air conditioning is a cost-effective way of heating or cooling multiple rooms in your home, when compared to purchasing a number of single room units or a ducted system. 

• Easy to maintain: While a multi room heat pump / air conditioner will still require periodic maintenance, not having to service ductwork or multiple outdoor units reduces the costs of servicing your system professionally.

Quiet operation: Many of Fujitsu General’s modern heat pump units feature super quiet and low-noise modes, making them perfect for bedrooms or home workplaces where less noise is needed.

A multi split heat pump system works most effectively at providing an efficient heating and cooling solution for more than one room or space in a home. This is particularly true for larger homes where the use of just a single-room heat pump / air conditioner may prove to be less effective.

With a multi heat pump / air conditioner, you can have several indoor units connected to a single outdoor unit, allowing each room to be set to its ideal temperature while using the same operating mode. This results in each room being set to a comfortable temperature for its occupants, rather than heating or cooling the entire house to the same temperature.

A multi heat pump / air conditioner is also more energy-efficient than running multiple single systems as it requires only one outdoor unit to operate multiple indoor units. This can help reduce your power consumption, which may lower your energy bills.

The primary difference between ducted heat pumps / air conditioners and multi split systems lies in the way the air is distributed throughout your home.

Multi split heat pump systems feature multiple indoor units that are matched to one outdoor unit. Indoor units are mounted in specific rooms and blow? conditioned air directly into those individual rooms. Each unit can be controlled separately, making it an ideal solution for homes with varying comfort preferences.

Ducted systems, on the other hand, consist of one main unit that blows air through a duct system hidden in floors, walls or ceilings. The air is then distributed through vents in individual rooms, providing a less visible look and uniform temperature throughout the home.

While multi split air conditioner systems are generally less expensive and easier to install, especially for existing homes, ducted systems may be more efficient and apt for bigger houses or new buildings.

For a comparison of the two, take a look at our article comparing multi split air conditioners vs ducted systems.

A single multi heat pump or air conditioning system can normally serve up to five rooms off a single outdoor unit, depending on the system's model and size.

These systems are designed to efficiently heat or cool multiple rooms by connecting one outdoor unit to several indoor units installed throughout your home. Each indoor unit can be individually controlled, offering personalised comfort in different spaces.

The number of rooms a multi air conditioner covers will depend on factors such as how your home is constructed, the size of the rooms and the capacity of the indoor and outdoor units combined. In larger residences or more complex configurations, several outdoor units may be used to cover additional rooms.

To ensure the right system for your needs, we recommend that you speak to a heat pump specialist who will call at your premises and advise on the most appropriate solution.

Modern multi split heat pumps / air conditioners are equipped with a number of features to make them more efficient and tailored to your individual needs. If you are looking at installing a heat pump in multiple zones throughout your home, there are a number of functionalities you should consider to help you choose the right unit:

• Timers: Many split system heat pump / air conditioners allow you to program their operation using a weekly timer. Some systems are also equipped with a specific Sleep Timer that adjusts the temperature and fan speed throughout the night to ensure a comfortable night’s sleep.

• Filters to improve air quality: A multi room heat pump / air conditioner with an inbuilt filter, such as the Apple-Catechin filter in Fujitsu’s wall mounted lifestyle model absorbs fine dust, invisible mould spores and harmful microorganisms. These systems can be particularly handy for allergy sufferers. 

• Economy mode: Multi room air conditioners that include economy mode as a feature can help reduce your energy bills, optimising the use of the unit to provide a comfortable temperature whilst drawing less power from the compressor.

• Adjustable fan speeds: For instances in which a sudden change in the amount of air being distributed is necessary, a multi split heat pump / air conditioner with adjustable fan speeds is both convenient and efficient.

Quiet operation: A quiet indoor unit operating mode, such as the Super Quiet Mode functionality of some of Fujitsu General’s multi room heat pumps / air conditioners, helps to lower the amount of noise emitted by the air conditioner, reducing distractions in bedrooms and study spaces.

Multi room heat pumps and air conditioners are generally energy-efficient, especially when compared to older or traditional systems.

They utilise the most advanced inverter technology to increase the compressor whenever it's required to supply the individual requirements of each room. That means the system only uses the energy needed, negating total consumption and helping to reduce your electricity bills.

Since each indoor unit is an independent unit, you can heat or cool rooms which you are currently using, avoiding wasted energy and maximising efficiency in your entire home.
