It is rated for rooms up to 45 m², making it a strong fit for large living areas. We confirm sizing against the room, insulation and sun exposure before installing, because right-sizing is what keeps running costs down.

The indoor unit runs at 25 – 44 dB(A). At the bottom of that range it is quieter than a whispered conversation, which is why we size systems to spend most of their time on low fan.

Assuming a typical Sydney tariff of 33–35c/kWh: at full output this unit draws roughly 1.8–1.9 kW of electrical input (typical efficiency for a modern inverter of this capacity), which works out to approximately 58 cents to 65 cents per hour. Real-world costs are usually lower once the room reaches temperature, because an inverter throttles right back. Your exact tariff, the model's rated input power, insulation, thermostat settings and system sizing all move the number.

A 5-year Mitsubishi Heavy Industries manufacturer warranty on the unit, plus a minimum 2-year warranty on our installation workmanship. We register the manufacturer warranty at commissioning, and ARCtick licensed installation is what keeps it valid.
