Experience comfort with Hitachi’s multi-split ACs

Hitachi’s multi-split AC system is a practical and affordable solution for homeowners looking to install air conditioning in multiple rooms, while using just one outdoor unit. Homeowners can choose any combination of indoor unit capacities for different room sizes or indoor unit types^[1] (such as wall-mounted, ducted, cassette or floor mounted / console) to fill varying room needs.

We also offer multi-split systems that combine an integrated domestic hot water heater and AC system in one^[1]. Connect one outdoor unit with our energy efficient hot water tank and up to 3 other indoor AC units, saving money while reducing environmental impact, to produce your cooling, heating and hot water needs.

– Free up more outdoor space with multi-split AC system

Depending on the system, you can connect up to 5 indoor units^[2] to just one outdoor unit, reducing the need to place equipment outside your home. Compared to using multiple Single-Split Systems (which require an outdoor unit for each indoor AC unit), multi-split systems frees up more outdoor space and minimizes the visual impact to your home exterior. The multi-splits system is an excellent choice that eliminates the hassle and extra cost associated with installing multiple single-split systems.

– Choice of indoor units for your Multi-Split AC system

Our Multi-Split AC system is a versatile solution. Enjoy the flexibility of combining different types of indoor units to make up your entire multi-split system:

Wall Mounted: easy to reach for cleaning and maintenance

Ducted: allows the AC units to be hidden in a ceiling plenum

Cassette: effective at distributing air evenly from the center of a larger open space

Floor mounted / Console: particularly effective in homes that require both heating & cooling as it takes advantage of the natural flow of warm air rising from the unit into the space

– Replace fossil fuel hot water systems

With our domestic hot water system^[1], you can replace gas, solid fuel and electric hot water systems with our integrated hot water and air conditioning system. Choose to combine our hot water heating tank with up to 3 indoor AC units, all powered from just one outdoor unit. With an A++ energy rating, it uses renewable energy contained in the air outside to heat water, and can easily connect with existing piping, radiators and underfloor heating to lower heating bills and environmental impact.

– Breathe healthier air with our air purifying ACs

Our indoor units come with air-purifying features^[1] to improve your indoor air quality. The PM2.5 Air Purifying Filter reduces the instance of PM2.5 particles by 99%^[3]. Working together with the Stainless Pre-filter, these 2 layers of filtration are 99% effective on inhibiting bacteria^[4], 95% on allergens^[5], and also have significant anti-mold^[6], and deodorizing properties.

– Control your Multi-Split AC system from anywhere

Experience the convenience of operating your AC from anywhere. You can use our airCloud Go app to control all aspects of the AC operation and access advanced functions such as viewing your energy consumption. Connect with a compatible smart speaker for voice-activated commands.
