12.5 kWMitsubishi Electric PEA High Static Ducted 12.5kW Ducted System
The 12.5kW Mitsubishi Electric PEA High Static Ducted (model PEA-M125HAA) is sized for typical three-bedroom single-storey homes. As a guide it covers roughly 83 to 100m² of conditioned floor area, depending on zoning, insulation and ceiling height. For more bedrooms or a larger floor plan, the 14kW is the next step up.
The Mitsubishi Electric PEA High Static Ducted 12.5kW carries a 2-star energy rating for both cooling and heating under the zoned label for Sydney's climate zone. Based on official government test data, it uses 1,274 kWh per year for cooling and 2,035 kWh for heating. At the median Sydney residential electricity rate of 34.7 cents per kWh as of June 2026, that works out to roughly $442 for cooling, $706 for heating, and $1,148 combined across a full year.
On the efficiency side, the unit has a rated AEER of 3.10 for cooling and an ACOP of 3.97 for heating, meaning it delivers more than three units of cooling or heating energy for every unit of electricity it consumes. The refrigerant is R32, which has a lower global warming potential than older refrigerants such as R410A.
