Toshiba Seiya Classic Series 9.0kW Reverse Cycle Split System — Commercial Capacity, Wall-Mounted Simplicity

At 9.0kW you’re into commercial territory while keeping the simplicity and lower installed cost of a wall-mounted split. It suits very large open areas of roughly 80–90 square metres where installing ductwork or a cassette isn’t practical or affordable.

Where we install this size

Warehouse offices and mezzanines, large retail tenancies, halls, gyms and dance studios, hospitality dining rooms, workshops, and very large open-plan homes with high ceilings. Also used to condition a large space quickly where trading hours mean ducted installation would be too disruptive.

Important pre-purchase checks

Confirm available wall space and structural support for a large indoor head, outdoor unit location with adequate airflow and service access, electrical capacity for a dedicated circuit, and whether a single head can physically distribute air across the space. For long, narrow or partitioned areas, two smaller units usually outperform one large one — we’ll model both options for you.
