8.6 kWCarrier QSH High Static 8.6kW Ducted System
The 8.6kW Carrier QSH High Static Ducted (indoor 42QSH090D8S) is rated at 8.6kW cooling and sized for typical three-bedroom single-storey homes. As a guide it covers roughly 57 to 69m² of conditioned floor area, depending on zoning, insulation and ceiling height. It runs R32 refrigerant and carries Carrier’s 7 year residential parts and labour warranty. It is the smallest unit in the QSH series. For more bedrooms or a larger floor plan, the 10.05kW is the next step up.
The Carrier QSH High Static 8.6kW carries a 3.5-star cooling rating and a 2.5-star heating rating under the zoned energy label for Sydney's climate. Based on official government test data for Sydney's climate zone, calculated to June 2026, annual cooling energy use is 695 kWh and annual heating energy use is 1241 kWh. Using the median Sydney residential electricity rate of 34.7 cents per kWh, that works out to roughly $241 for cooling, $431 for heating, and $672 combined across a typical year.
The rated AEER of 3.32 and ACOP of 3.88 reflect how efficiently the unit converts electricity into cooling and heating output respectively. The system uses R32 refrigerant, which has a lower global warming potential than older refrigerants.
