Description

The LG Viero KUSAE121A-KNSAE121A mini split system delivers 12,000 BTU of zoned heating and cooling in a compact, high-efficiency design. Engineered for wall-mounted indoor installation, it operates with R-410A refrigerant and inverter-driven performance for smooth, responsive comfort. With efficiency ratings up to 26.0 SEER2 and 11.5 HSPF2, this system meets the demands of energy-conscious homeowners and professionals seeking reliable year-round climate control.

Performance
This system uses a variable-speed inverter compressor to optimize energy usage while minimizing temperature swings and power surges. A durable heat exchanger and high-efficiency coil design improve thermal performance and longevity. Its airflow capacity reaches up to 335 CFM, ensuring even, consistent air distribution. These features combine to provide responsive operation in both heating and cooling modes with excellent part-load efficiency.

Smart Features
The KUSAE121A-KNSAE121A is Wi-Fi ready and fully compatible with the LG ThinQ smart platform. Users can control temperature, fan speed, and scheduling through the ThinQ mobile app or via smart home assistants like Google Assistant and Alexa. Advanced zoning capabilities allow for precision control in specific rooms, optimizing comfort while minimizing wasteful energy use.

Comfort & Noise
Designed for whisper-quiet operation, this system operates at sound levels as low as 19 dBA indoors—barely louder than a whisper. The multi-directional airflow system includes motorized louvers for uniform temperature coverage. Features like Auto Mode, Sleep Mode, and customizable fan speeds deliver a tailored comfort experience, making it ideal for spaces where noise and consistency matter most.

Use Case Fit
With its 12,000 BTU capacity, this model is ideal for mid-sized residential spaces, such as master bedrooms, small apartments, or office suites. It also works well in hospitality settings or multifamily upgrades where energy savings and comfort control are key priorities. Designed for year-round use, this system adapts well to a variety of U.S. regional climates, including cold winters and humid summers.

Value & Reliability
Engineered with LG’s robust build standards, this mini split system combines energy-efficient operation with long-lasting reliability. The corrosion-resistant outdoor unit and smart diagnostic capabilities help extend operational life and reduce maintenance needs. The inverter-driven compressor reduces wear and tear by ramping speed up or down based on demand, improving overall service life.
