Commercial spaces rarely follow a perfect HVAC layout.
One room may have limited wall space. Another may have a high ceiling. A restaurant may need to keep walls clear for seating and décor, while a showroom may have floor-to-ceiling glass that leaves almost nowhere for a conventional indoor unit.
That is where the TOSOT Aoraki Floor/Ceiling Mini-split offers a different kind of flexibility.
Available in 18,000 and 24,000 BTU capacities, the Floor/Ceiling indoor unit can be installed in more than one orientation, giving contractors greater freedom to work around the actual building rather than forcing the building to work around the HVAC system.
One Indoor Unit, More Installation Possibilities
The defining advantage of a Floor/Ceiling unit is right in the name.
Depending on the layout of the space, the indoor unit can be positioned for a floor-level installation or suspended near the ceiling, making it particularly useful for commercial spaces where a traditional high-wall mini split is not practical.
This flexibility can be valuable in:
- Restaurants and cafés
- Retail stores and showrooms
- Offices and conference spaces
- Studios and fitness facilities
- Workshops
- Commercial spaces with extensive glazing
- Renovation projects with limited mounting locations
For a room with large windows, for example, usable wall space may be extremely limited. In another application, keeping equipment close to the ceiling may provide a cleaner layout.
Instead of being locked into one installation position, contractors have more options when planning airflow and equipment placement.
Up to 82 Feet of Vertical Installation Flexibility
Commercial mini-split installations often require greater distance between the indoor and outdoor equipment than a typical residential project.
Both the 18K and 24K Aoraki Floor/Ceiling systems support a maximum indoor-to-outdoor height difference of up to 82 ft.
That extra vertical flexibility can be especially useful when the outdoor condenser needs to be installed at ground level while the indoor unit serves an upper floor—or when outdoor equipment must be placed on a rooftop or designated mechanical area.
For multi-story buildings and challenging retrofit projects, installation flexibility is not simply convenient. It can determine whether a system is practical at all.
Efficient Performance for Light-Commercial Spaces
The Floor/Ceiling lineup combines flexible installation with strong seasonal efficiency.
The 18,000 BTU model reaches up to 21.5 SEER2 and 9.5 HSPF2, while the 24,000 BTU model reaches up to 22.5 SEER2 and 9.5 HSPF2.
That means the system is designed not only around peak heating and cooling output, but also around efficiency over an entire season.
For businesses that may operate HVAC equipment for many hours every day, seasonal efficiency can have a meaningful impact on long-term operating costs.
Built for Extreme Conditions From -40°F to 140°F
Commercial HVAC systems may need to operate through more than a typical summer or winter season.
The Aoraki Light Commercial platform is engineered for an extreme outdoor operating range from -40°F to 140°F, helping it support indoor comfort across severe winter conditions as well as intense summer heat.
That broader temperature capability can be especially valuable for restaurants, offices, retail stores, workshops, and other commercial environments where HVAC operation cannot simply stop when outdoor conditions become extreme.
The series also includes intelligent defrost and forced defrost functions to help manage frost buildup during cold-weather heating operation.
For unattended spaces, an 8°C / 46°F freeze-protection mode can help maintain a minimum indoor temperature and reduce the risk of freezing pipes when a building is temporarily unoccupied.
Extra Heating Support on the 24K Model
For applications that need additional heating capability, the 24,000 BTU Floor/Ceiling model includes auxiliary electric heat.
This gives the larger-capacity model another layer of support for colder climates or commercial environments where maintaining indoor temperature is especially important.
This additional heating capability can be useful in colder climates or commercial environments where maintaining indoor temperature during winter is especially important.
Why We Continue to Use R32
Refrigerant choice affects more than system design. It also influences installation, servicing, and long-term ownership.
When developing the Aoraki Light Commercial Series, TOSOT considered feedback from users and contractors, including their familiarity and preferences regarding refrigerants. Based on that feedback, we chose to continue using R32 refrigerant across the series.
R32 is already widely used in modern heat pump and mini-split applications, making it a familiar option for many HVAC professionals. It also has a lower global warming potential than many older-generation refrigerants. TOSOT is getting ahead of the curve, helping our customers prepare for future compliance while also reducing our carbon footprint.

Backed by GREE Compressor and Manufacturing Experience
The Aoraki Light Commercial Series uses GREE (LANDA) compressors, backed by GREE's HVAC engineering and manufacturing experience. The systems also feature inverter-driven operation, low-voltage startup, intelligent defrost control, and multiple fan speeds for reliable performance across changing operating conditions.
Conclusion
With 18K and 24K capacities, floor-or-ceiling installation options, up to 82 feet of vertical separation, an operating range from -40°F to 140°F, and efficiency ratings up to 22.5 SEER2, the Aoraki Floor Ceiling mini split AC gives contractors another solution for light commercial spaces where conventional wall-mounted systems may not be the right fit.
It is well suited for restaurants, retail stores, offices, studios, and challenging retrofit applications, providing greater flexibility for spaces with limited wall space or unique installation requirements.
