Common questions about the Gree Aoky 6kW Window Wall Reverse Cycle Box Air Conditioner GJH21AE
How much does the Gree Aoky 6kW Window Wall Reverse Cycle Box Air Conditioner GJH21AE cost installed?

Supply-only is $1,211. Our instant quote calculator confirms the installed price for your home from your address.
What room size does the Gree Aoky 6kW Window Wall Reverse Cycle Box Air Conditioner GJH21AE suit?
Sizing depends on the space. We confirm sizing against the room, insulation and sun exposure before installing, because right-sizing is what keeps running costs down.
How much does the Gree Aoky 6kW Window Wall Reverse Cycle Box Air Conditioner GJH21AE cost to run?
Assuming a typical Sydney tariff of 33–35c/kWh: at full output this unit draws roughly 1.7–1.8 kW of electrical input (typical efficiency for a modern inverter of this capacity), which works out to approximately 55 cents to 62 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.
What warranty does the Gree Aoky 6kW Window Wall Reverse Cycle Box Air Conditioner GJH21AE come with?
The full Gree manufacturer warranty, with support from our team if anything needs attention.
