Description
The LG Viero KUSAL181A‑KNSAL181A is a high-performance ductless mini split heat pump system delivering 18,000 BTU of heating and cooling power. This wall-mounted unit uses eco-friendly R‑410A refrigerant and features a variable‑speed inverter compressor for smooth, efficient operation. Rated up to 21.5 SEER2 and 10.5 HSPF2, it offers precise temperature control with reduced energy consumption. Designed for both residential and light commercial spaces, this model supports zoning flexibility and smart connectivity, making it ideal for modern HVAC solutions.
Performance
Powered by LG’s inverter technology, the compressor modulates output continuously to match changing indoor loads, minimizing cycling and energy waste. The advanced coil design and electronic expansion valve enhance heat exchange efficiency, while airflow reaching up to 530 CFM ensures rapid and even distribution. These features provide stable and responsive comfort in temperatures ranging from summer heatwaves to winter cold.
Smart Features
The KUSAL181A‑KNSAL181A integrates with LG ThinQ™, enabling full control via smartphone app and voice commands (Google Assistant, Amazon Alexa). Users can manage schedules, set temperature presets, and monitor energy usage remotely. Smart diagnostics alert users and service technicians to any maintenance needs or performance issues, making the system both user- and technician‑friendly.
Comfort & Noise
Indoor sound levels drop to as low as 27 dBA, offering whisper-quiet operation suitable for bedrooms, home offices, and libraries. Multi-speed fans and auto-swing louvers ensure consistent airflow without drafts. Sleep mode and humidity control fine-tune nighttime environments, supporting both comfort and energy conservation.
Use Case Fit
This 18,000 BTU unit is ideal for larger single-zone applications such as living rooms, open-concept spaces, master suites, garages, or light commercial offices. Its high capacity and zoning flexibility allow contractors and property managers to deliver targeted comfort solutions in varying U.S. climate zones—from Northern cold to Southern humidity.
Value & Reliability
Built to LG’s rigorous quality standards, the system features anti-corrosion coatings and a durable outdoor unit designed for long-term performance—even in coastal or humid environments. The inverter compressor reduces mechanical stress and maintenance needs, and integrated diagnostics facilitate efficient servicing, delivering exceptional reliability.
