9.5 kWMHI Bronte 9.5kW Split System
The 9.5kW MHI Bronte Split (model DXK33ZRA-W) is sized for very large open-plan rooms and light commercial spaces. As a guide it suits a typical insulated room of roughly 63 to 76m²; sun exposure and ceiling height move that band. If the space is bigger, has high ceilings or strong afternoon sun, step up to the 10kW.
The MHI Bronte 9.5kW carries a 3.5-star cooling rating and 2.5-star heating rating under the zoned energy label for Sydney's climate. Based on official government test data for the Sydney climate zone, calculated at the median Sydney residential electricity rate of 34.7 cents per kWh as of June 2026, estimated annual cooling costs are $268 (773 kWh) and annual heating costs are $445 (1281 kWh), giving a combined year-round running cost of $713.
The unit's rated AEER of 3.69 and ACOP of 3.88 indicate how much cooling and heating output it delivers per unit of electricity consumed. It uses R32 refrigerant, which has a lower global warming potential than older refrigerants.
