LG 42,000 BTU 21.5 SEER2 3 Zone Wall Mount Mini Split Heat Pump System R32 | 230V 18 + 9 + 9
The LG Multi F 18 + 9 + 9 configuration is a high performance multi zone solution designed to provide tailored climate control for approximately 1,100–1,800 sq ft. This setup is ideally suited for homes featuring one expansive common area, such as a vaulted great room, paired with two medium sized bedrooms or home offices. The primary benefit of this system lies in its "over engineered" 42,000 BTU outdoor chassis; by providing more raw capacity than the indoor heads require at peak, it ensures consistent, high velocity heating and cooling even when outdoor temperatures reach record breaking extremes.
Key Features
- Covers up to 1,800 sq ft (Ideal for one large master zone and two secondary rooms)
- High efficiency 21.5 SEER2 rating
- Built in Wi-Fi Compatibility
- Inverter Variable Speed Compressor for precise temperature maintenance and lower vibration
- Gold Fin™ Anti Corrosion Coating for enhanced outdoor unit durability and protection
Feature Highlights
Efficiency (SEER2)
Boasting a 21.5 SEER2 rating, this system is engineered to maximize every watt of electricity, significantly lowering seasonal energy costs. The advanced inverter technology allows the compressor to modulate its speed in real time, matching the thermal demand of each room exactly rather than cycling on and off like traditional, less efficient HVAC systems.
Quiet Operation
LG's indoor wall mounted units utilize a unique skew fan and Brushless DC (BLDC) motor technology to minimize air turbulence and mechanical noise. Operating at sound levels as low as 19 dB, this system provides a tranquil environment that is essential for bedrooms, nurseries, or home offices where focus and rest are priorities.
Right Sized Power
The 18 + 9 + 9 layout provides a strategic power split for modern residential floor plans. The 18,000 BTU indoor unit offers the high volume airflow necessary for large, open concept spaces, while the two 9,000 BTU units offer dedicated, efficient conditioning for smaller zones, ensuring no room is underserved during peak summer heat or winter freezes.
