LG 18,000 BTU Multi F 20 SEER2 Three Zone Wall Mount Mini Split Heat Pump System – R32 | 230V - 9+9+9

The LG Multi F three-zone system is an ultra-efficient climate control solution designed to cover up to 1,000–1,200 square feet across three separate rooms. By utilizing three 9,000 BTU indoor units, this system provides personalized comfort for bedrooms, home offices, or smaller living areas, allowing you to heat or cool only the spaces you are using for maximum energy savings.

Key Features

  • Covers up to 1,000–1,200 square feet
  • 20 SEER2 efficiency rating
  • Built in Wi-Fi Compatibility
  • Inverter technology automatically adjusts compressor speed to maintain precise temperatures with minimal energy pull.
  • Multi-zone flexibility allows for independent temperature settings in three different areas of the home.

Feature Highlights

Efficiency (SEER2) With an impressive 20 SEER2 rating, this system is one of the most efficient ways to manage your home's climate. The higher SEER2 rating means significantly lower operational costs and a reduced environmental impact without sacrificing powerful cooling or heating performance.

Quiet Operation LG's indoor wall-mounted units are designed with skewed fan technology and a brushless DC motor to minimize noise. This ensures a peaceful indoor environment, making it an excellent choice for bedrooms or study areas where silence is just as important as temperature.

Right-Sized Power Distributing 18,000 BTUs across three 9,000 BTU heads ensures that small-to-medium rooms receive consistent airflow without the "on-off" cycling of oversized units. This creates a more balanced environment and prevents hot or cold spots throughout your 1,000 square foot layout.
