The LG B55AWY-7G6 is a high static reverse cycle ducted air conditioning system designed for very large homes, offices, and commercial spaces that require strong airflow, long duct runs, and flexible zoning. Its high static pressure capability and compact indoor unit make it ideal for larger multi-room properties, open-plan areas, and demanding ducted installations. The system includes LG’s PREMTB001 backlit wired wall controller for simple day-to-day operation.
With 15.0kW cooling and 17.0kW heating capacity, this model is ideal for very large open-plan living areas, offices, shops, and spaces around 70–110m² depending on insulation and layout. It can modulate from approximately 4.0kW to 16.5kW in cooling mode and from 4.5kW to 18.0kW in heating mode, helping maintain more stable temperatures while reducing running costs.
Key Features & Benefits
High Static Pressure Performance
The system supports strong airflow for long duct runs, multiple outlets, and larger zoned ducted systems. Airflow ranges from approximately 533 litres per second on high fan speed down to 333 litres per second on low fan speed, helping maintain even air distribution throughout larger homes and commercial spaces.
Single-Phase Power Supply
This model operates on standard 220–240V single-phase power, making it suitable for large residential homes without requiring a 3-phase electrical upgrade. Rated running current is approximately 11.4 amps in cooling mode and 10.3 amps in heating mode, with a recommended 25-amp circuit breaker.
Energy Efficient Inverter Twin Rotary Compressor
The system uses an inverter twin rotary compressor to automatically adjust output based on room conditions. This helps deliver more stable temperatures, quieter operation, and lower running costs than fixed-speed systems. It achieves an EER of approximately 3.41 and a COP of approximately 4.05.
Compact Indoor Unit Design
The indoor unit measures approximately 1320mm wide, 400mm high, and 534mm deep, while the outdoor unit measures approximately 950mm wide, 834mm high, and 330mm deep. Despite its larger capacity, the system remains compact enough for many residential roof spaces.
Quiet Operation
Indoor sound levels are approximately 41dBA on high fan speed, 40dBA on medium, and 39dBA on low fan speed. Outdoor sound pressure levels are approximately 51dBA in cooling mode and 52dBA in heating mode, helping maintain quieter day-to-day operation for a system of this size.
Zone Control Compatible
The system supports optional zoning for up to eight zones, allowing users to independently control airflow to different areas of the home. This can help improve comfort and reduce unnecessary energy use in unused rooms.
Wi-Fi Smart Control Compatible
The LG ThinQ® app allows remote control of the system through an optional Wi-Fi module, making it easy to adjust temperature, operating mode, and timers from a smartphone.
Backlit Controller Included
The included LG PREMTB001 wired wall controller features a backlit display, timer functions, fan speed adjustment, filter reminders, and simple operating controls for day-to-day use.
Wide Operating Range
The unit can operate in outdoor temperatures from -15°C to 48°C in cooling mode and from -18°C to 18°C in heating mode, making it suitable for Australian climate conditions year-round.
5 Year Manufacturer Warranty
LG ducted systems include a 5-year manufacturer warranty when installed by a licensed technician in accordance with manufacturer guidelines.
Ideal Applications
- Very large homes
- Open-plan living areas
- Multi-room homes
