Fujitsu AOUH09KUBS & AGUH09KUAS 9,000 BTU 26 SEER2 Floor Mounted Heat Pump System

Fujitsu AIRSTAGE AGUH09KUAS & AOUH09KUBS: 9,000 BTU Floor-Mounted Heat Pump System

The Fujitsu AIRSTAGE AGUH09KUAS floor-mounted indoor unit paired with the AOUH09KUBS outdoor heat pump delivers efficient year-round heating and cooling in a compact, low-wall design. Ideal for spaces where wall-mounted systems are not practical, this 9,000 BTU single-zone system combines quiet operation, advanced inverter technology, built-in Wi-Fi connectivity, and reliable cold-weather performance to provide exceptional comfort for residential applications.

The AGUH09KUAS indoor unit is specifically designed for installations where wall space is limited, making it an excellent solution for bedrooms, sunrooms, additions, finished basements, and other living spaces. Its floor-mounted design delivers powerful airflow at occupant level while maintaining an attractive, low-profile appearance. Multiple fan speed settings—including Auto, High, Medium, Low, and Quiet modes—allow users to customize comfort and airflow based on seasonal requirements and personal preferences. Whisper-quiet operation with sound levels as low as 22 dB(A) helps create a comfortable indoor environment without distracting noise.

Advanced comfort features include Economy Mode, Energy Saving Mode, Powerful Mode, Minimum Heat Mode, Automatic Defrost, and Auto-Restart functionality. Built-in Wi-Fi connectivity enables remote monitoring and control through the Fujitsu AIRSTAGE Mobile App, allowing users to adjust temperature settings, schedules, and operating modes from virtually anywhere. Flexible control options also support optional wireless and wired controllers, BACnet® integration, Modbus® compatibility, and third-party interface solutions for expanded control flexibility.

The AOUH09KUBS outdoor unit utilizes Fujitsu’s advanced inverter-driven compressor technology to precisely adjust capacity based on heating and cooling demand. This variable-speed operation helps reduce energy consumption, improve temperature consistency, and minimize operating noise compared to traditional fixed-speed systems. The heat pump provides efficient cooling during the summer and dependable heating during colder months, making it a versatile comfort solution for year-round use.

For added convenience and safety, the AGUH09KUAS includes a built-in refrigerant leak detection sensor, integrated external input/output terminals for third-party device connectivity, group control capabilities, auxiliary heat management options, and advanced service monitoring functions. Weekly timers, 24-hour timers, and sleep mode functions allow users to create customized comfort schedules while maximizing efficiency.
