Powerful Cooling & Heating for Year-Round Comfort: This 11500 BTU mini split AC/heating system delivers efficient year-round climate control for spaces requiring reliable temperature management. With a heat pump design, it operates in cooling mode (room temp 63-90℉) and heating mode (room temp 32-80℉), while inverter models maintain performance in low outdoor temperatures down to 5℉. Energy-Saving & Eco-Friendly Design: This energy-efficient split AC unit uses advanced technology and R32 refrigerant, a green solution with low environmental impact. The ECO mode optimizes operation to reduce energy use, and inverter technology (for applicable models) adjusts compressor speed to avoid frequent starts/stops, boosting efficiency. ETL and AHRI certified, it guarantees reliable performance. Versatile Modes & User-Friendly Features: Equipped with 7 operating modes (Auto/Cool/Heat/Dry/Fan/Sleep/ECO) and multiple fan speeds (Auto/Low/Low-Mid/Mid/Mid-High/High/TURBO), it caters to diverse comfort needs. Convenient functions include a 24-hour timer, 4D auto swing (up-down & left-right), child lock, I FEEL mode (measures temperature at the remote), HEALTH mode, and TURBO function for quick cooling/heating. Quiet Operation & Easy Maintenance: Enjoy peaceful comfort with a MUTE function that lowers the indoor unit fan to the lowest level for ultra-quiet operation. The sleep mode ensures undisturbed rest, automatically adjusting settings after 10 hours. Maintenance is simple with a washable air filter—just clean it regularly to maintain airflow and air quality. Professional Installation & Reliable Performance: This 11500 BTU mini split requires professional installation by licensed HVAC technicians to ensure safety and optimal performance, as per the installation guidelines. Pre-charged with refrigerant, the system supports a maximum distance of 15m/49ft between indoor and outdoor units (for 9K-12K BTU inverter models).
