Fujitsu AOU18RLXFZH Mini Split Outdoor Condenser: Efficient Comfort for Your Home

Reliable Comfort, Proven Performance:

For years, a leading brand in heating and air conditioning, Fujitsu delivers dependable solutions like the AOU18RLXFZH mini split outdoor condenser. This versatile unit efficiently powers up to two indoor units, making it ideal for multi-zone climate control.

Advanced Technology, Superior Efficiency:

Featuring inverter technology, the AOU18RLXFZH precisely adjusts its output to match your needs, resulting in consistent and comfortable temperatures. This innovative operation also reduces moisture, minimizes short-cycling, and enhances overall efficiency.

Flexible Design, Personalized Comfort:

The AOU18RLXFZH offers exceptional design flexibility by allowing connection of indoor units with a total capacity exceeding  130% of the outdoor unit's capacity. When all zones are active, the system adjusts individual outputs for balanced comfort. As zones reach desired temperatures, the available capacity automatically redirects to areas still requiring heating or cooling.

Unmatched Performance in Extreme Conditions:

Engineered for exceptional performance in harsh winter conditions, the AOU18RLXFZH maintains its rated capacity down to 3°F. Even at -15°F, it delivers an impressive 73% of its heating capability. Additionally, the built-in base pan heater prevents damage caused by frozen condensate, ensuring reliable operation in cold climates.

Durable Construction, Lasting Performance:

Fujitsu's commitment to quality extends to the AOU18RLXFZH 's corrosion-resistant heat exchanger. Featuring a special blue fin coating, it effectively resists various corrosive elements, ensuring long-lasting performance and reliable operation.

Additional Notes:

This product requires two compatible Fujitsu mini split indoor units and specific installation accessories, including line sets, drain tubing, and connecting cables, to ensure proper functionality.



East Bay Air Systems will contact you to schedule a pre-installation home visit before scheduling your installation. These appointments typically last 30-45 minutes and are available Monday-Friday between 9:00 AM and 5:00 PM. We strive to complete installations within 10-15 business days of your purchase.

Please note that all wall-mounted interior units must be installed on an exterior wall.

The interior and exterior units will be connected by an insulated refrigerant line, also called a "line set," which will be covered in Rectorseal "Slimduct" for insulation.
