18 kWMitsubishi Electric Large Capacity Ducted 18kW Ducted System
The 18kW Mitsubishi Electric Large Capacity Ducted (model PEA-M180LAA) is sized for large two-storey family homes. As a guide it covers roughly 120 to 144m² of conditioned floor area, depending on zoning, insulation and ceiling height. It is the smallest capacity in the Mitsubishi Electric Large Capacity Ducted range. For more bedrooms or a larger floor plan, the 20kW is the next step up.
The Mitsubishi Electric Large Capacity Ducted 18kW carries a 2.5-star energy rating for both cooling and heating under the zoned label for Sydney's climate zone. Based on official government test data for that zone, calculated in June 2026, the system uses 1,749 kWh of electricity for cooling and 2,679 kWh for heating across a typical year. At the median Sydney residential rate of 34.7 cents per kWh, that works out to roughly $607 for cooling, $930 for heating, and $1,537 combined annually.
The rated AEER of 3.20 and ACOP of 3.84 reflect how many units of cooling or heating the system delivers per unit of electricity consumed. The system uses R32 refrigerant.
