Key Features
- Covers up to 1,800 sq ft (ideal for three large 400–600 sq ft zones)
- High efficiency 20.8 SEER2 rating
- LG Inverter Technology for whisper quiet operation and precise temperature maintenance
- Superior heating and cooling reserves for large scale residential or light commercial use
Feature Highlights
Efficiency (SEER2)
Boasting a 20.8 SEER2 rating, this system is engineered to provide maximum thermal comfort while significantly reducing energy waste. By utilizing a variable speed compressor, it consumes only the power necessary to maintain your desired temperature, leading to substantial savings on monthly utility bills.
Quiet Operation
Designed with the homeowner’s peace in mind, LG’s indoor units feature a unique skew fan and Brushless DC (BLDC) motor technology. Operating at sound levels as low as 19–23 dB, this system provides a powerful climate solution that remains virtually silent, making it ideal for bedrooms and home offices.
Right Sized Power
The "MAX" series 48,000 BTU condenser provides an incredible amount of power for this three zone configuration. This ensures that even when all three 12,000 BTU units are working at peak demand, the system has the "headroom" to maintain performance without straining, extending the overall lifespan of the equipment.
