S4 W12JA2MA

Begin with the cooling and heating needs of your room. The S4-W12JA2MA models are inverter-based and offer 1.5 HP cooling with heating, ensuring energy-efficient climate control. The variants differ in features like Wi‑Fi connectivity and UVnano technology for cleaner air; the version with UVnano and 4-Way Air Distribution delivers broader room coverage. Some models include professional installation by LG, and the inverter compressor warranty extends for up to 10 years, which is ideal for long-term use in homes.

UVnano technology eliminates 99.99% of bacteria on the fan, contributing to cleaner, healthier air within the unit. This feature is present on the S-PLUS models and can be particularly beneficial for households seeking enhanced indoor air quality. While it doesn’t replace regular cleaning, it complements smart cooling with a focus on hygiene, especially in spaces with shared living or allergy sensitivities.

Wi‑Fi connectivity allows remote control and monitoring through a compatible app, so you can adjust settings, schedules, and modes from your phone. The S-PLUS line with Wi‑Fi provides this convenience, making it easy to manage cooling and heating when you’re away. It also supports faster troubleshooting through app-based diagnostics and status updates.

The S-PLUS models offer both cooling and heating with inverter technology, designed for year-round comfort. If you live in a climate with seasonal changes, these all-in-one units provide consistent temperature control and potential energy savings due to their inverter design. Compare the models’ exact BTU/h and airflow features to ensure adequate coverage for your room size.

Most S-PLUS units come with a 10-year warranty on the inverter compressor, reflecting long-term reliability. Installation is often performed by the seller or a certified technician, sometimes included in the package, which helps ensure proper mounting and refrigerant handling. This combination of warranty and professional setup is designed to offer smooth operation and peace of mind for residential use.

For a balance of efficiency and smart control, the S4-W12JA2MA with Wi‑Fi and UVnano provides convenient remote management and improved air hygiene. If you want the strongest airflow distribution and a focus on broader coverage, the unit with 4-Way Air Distribution is a good pick. Either way, the inverter technology helps reduce energy consumption while delivering reliable cooling and heating across daily use.
