Experience comfort with Hitachi’s multi-split AC systems

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 (such as wall-mounted, ducted, cassette or floor mounted) to fill varying room needs.

Free up more outdoor space with multi-split AC system

You can connect up to 5 indoor units 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: 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
