Fujitsu AOUH36KUAH1 – 36,000 BTU AIRSTAGE Centauri XLTH R-32 Heat Pump Outdoor Unit

Deliver exceptional year-round efficiency and reliable cold-climate heating performance with the Fujitsu AOUH36KUAH1 , a 36,000 BTU-class AIRSTAGE Centauri XLTH inverter-driven heat pump outdoor unit. Designed for use with the AMUH36KUAS multi-position ducted air handler and compatible non-wall-mounted indoor unit configurations, this advanced single-zone system combines high efficiency, extended low-temperature operation, and durable construction for dependable whole-home residential and light commercial heating and cooling.

Extreme Cold-Climate Heating Performance
Engineered for demanding winter climates, the AOUH36KUAH1 provides reliable rated heating operation down to -15°F (-26°C) . When paired with the AMUH36KUAS indoor unit, the system delivers a rated 38,000 BTU/h heating capacity at 47°F , exceeding its nominal 36,000 BTU/h cooling capacity. It maintains 41,000 BTU/h of heating capacity at 5°F and is designed to retain approximately 80% heating capacity at -15°F . Fujitsu also specifies heating performance exceeding 100% capacity at 0°F. A factory-installed base pan heater further supports dependable operation in freezing conditions by helping manage ice accumulation.

High-Efficiency Inverter Performance
Fujitsu’s inverter-driven compressor continuously adjusts system output to match changing comfort demands, helping maintain consistent indoor temperatures while reducing unnecessary energy consumption. When paired as the 36KUAH1M system, it achieves an impressive 18.3 SEER2 , 11.4 EER2 , 10.2 HSPF2 (Region IV) , 8.2 HSPF2 (Region V) , and 3.9 COP2 , delivering excellent heating and cooling efficiency. The matched system also meets ENERGY STAR®, ENERGY STAR Cold Climate, and ENERGY STAR Most Efficient qualifications.

Wide Modulating Capacity Range
The AOUH36KUAH1 provides much more than fixed 36,000 BTU performance. When matched with the AMUH36KUAS, cooling capacity modulates from approximately 9,600 to 39,000 BTU/h , with a rated cooling capacity of 36,000 BTU/h , while heating output at 47°F ranges from approximately 9,200 to 43,000 BTU/h , with a rated heating capacity of 38,000 BTU/h . At lower outdoor temperatures, the system provides a rated 25,200 BTU/h at 17°F , with a maximum capacity of 41,600 BTU/h , and delivers 41,000 BTU/h at 5°F . This broad operating range allows the inverter system to closely match changing loads for improved comfort and efficiency throughout the year.

Extended Heating & Cooling Operation
Built for year-round performance, the system has a rated outdoor cooling operating range of -5°F to 122°F (-21°C to 50°C) and a heating operating range of -15°F to 75°F (-26°C to 24°C) . This wide operating envelope makes the AOUH36KUAH1 particularly well suited for regions that experience both extremely cold winters and hot summers. Its low-ambient cooling capabilities also provide additional flexibility for applications requiring cooling during colder outdoor conditions.

Flexible Installation & Extended Line Lengths
The outdoor unit supports refrigerant line lengths of up to 246 ft , with a maximum height difference of 98 ft , providing excellent flexibility when locating the outdoor unit away from the conditioned space. It uses standard 3/8″ liquid and 5/8″ gas flare connections and comes factory pre-charged for up to 98 ft of piping , with a minimum line length of 17 ft . These extended piping capabilities make the AOUH36KUAH1 a versatile solution for residential and light commercial installations where equipment placement flexibility is essential.

Compact, Durable Outdoor Construction
Measuring approximately 39-5/16″ H × 37″ W × 12-5/8″ D and weighing approximately 159 lb , the AOUH36KUAH1 delivers powerful heating and cooling performance in a space-efficient outdoor design. A Blue Fin-coated heat exchanger helps improve corrosion resistance and coil durability, supporting long-term reliability in demanding outdoor environments. The unit features a high-performance propeller fan capable of delivering approximately 2,266 CFM in cooling and 2,148 CFM in heating , while maintaining outdoor sound pressure levels of approximately 53 dB(A) in both cooling and heating .

Advanced Controls & Connectivity
When paired with the compatible AMUH36KUAS indoor unit, the system supports optional Wi-Fi connectivity for remote monitoring and control through the AIRSTAGE Mobile App , along with wired and wireless controller options and expanded third-party integration. Compatible accessories provide support for 24V thermostat interfaces, BACnet®, Modbus®, external input/output controls, and advanced building-management integration , allowing the system to accommodate applications ranging from straightforward residential control to more sophisticated commercial automation configurations. The compatible ducted air handler also supports optional electric heater kits, auxiliary heat integration, emergency heating controls, and Airzone communicating zoning systems, providing additional flexibility for whole-home comfort applications.

Environmentally Conscious R-32 Refrigerant
The AOUH36KUAH1 uses R-32 refrigerant , providing a lower-GWP refrigerant solution while supporting Fujitsu’s high-efficiency heat pump technology. The outdoor unit carries a factory refrigerant charge of 5 lb. 15 oz. (2,700 g) , with an additional refrigerant charge rate of 0.43 oz. per foot when required for extended piping installations. This environmentally conscious refrigerant technology helps reduce the system's environmental impact while maintaining dependable heating and cooling performance.

Ideal for homeowners and light commercial applications seeking premium efficiency, dependable low-temperature heating performance, extended installation flexibility, and advanced inverter technology , the Fujitsu AOUH36KUAH1 AIRSTAGE Centauri XLTH outdoor unit provides powerful, energy-efficient heating and cooling performance even in demanding climate conditions.
