Daikin 24,000 BTU 21 SEER2 Wall Mounted Ductless Mini Split Cooling Only System OTERRA Series R32 Refrigerant | RXF24AXVJU-FTKF24AXVJU

The Daikin Oterra RXF24AXVJU outdoor heat pump condenser, paired with the FTXF24AXVJU wall‑mount indoor unit, delivers approximately 24,000 BTU cooling capacity and 23,600 BTU heating capacity. It achieves a notable 21 SEER2 and 9.1 HSPF2 (non‑ducted testing), utilizing R‑32 refrigerant in this wall‑mount, single‑zone ductless setup. This inverter-driven system is engineered for efficient climate control with precise capacity modulation, supporting piping runs up to 99 ft total length and vertical lifts up to 66 ft.

Performance
Equipped with a variable-speed inverter compressor and a high-efficiency fin-and-tube coil, the Oterra system delivers up to 30 % energy savings over fixed-speed ducted units. Under rated conditions, it produces ~22,400 BTU cooling from a 6.57 kW input, yielding an EER2 of 12.0 and a COP of 3.3 in heating mode. The system reliably operates in ambient temperatures from 50–122 °F for cooling and from 5 °F WB (with extended down to –4 °F DB) for heating.

Smart Features
The Oterra series supports the DKN Cloud app for remote monitoring and control — ideal for smart homes, zoned applications, and property management. Featuring auto-changeover, Eco+ and dry modes, and self-diagnostics with a wireless backlit remote, the system offers user-friendly, contractor-friendly controls. It is also compatible with the Daikin ONE+ smart thermostat for two-way communication and third-party integrations for professional-grade installations.

Comfort & Noise
The indoor unit operates quietly, with sound levels ranging from 34 dBA (super‑quiet) to 53 dBA (high), and airflow rates between 395–754 CFM depending on fan speed. The outdoor unit achieves about 55 dBA at high fan speed . Blue Fin hydrophilic coil coating, quick‑warm technology, and automatic defrost ensure steady performance and enhanced comfort in varied climates.

Use Case Fit
Ideal for residential, commercial, multi-family, or retrofit applications, the 24 k BTU capacity serves spaces up to ~1,500 sq ft. Its extensive operating range—from Florida heat to northern chills—makes it suitable across U.S. climate zones. Compact wall-mount installation is space-efficient, appealing to homeowners, contractors, and property managers working on additions, attics, sunrooms, or office conversions.

Value & Reliability
Daikin’s Oterra builds on decades of HVAC innovation with corrosion-resistant coils, 16-hole outdoor drain pans, and anti-corrosion treatments. The system offers simplified maintenance access, inverter-based durability, and robust diagnostics for reduced service time. With strong OEM support and clean rebate eligibility, it delivers long-term ROI for wholesale and commercial channels .

Summary Wrap‑Up
The Daikin Oterra RXF24AXVJU–FTXF24AXVJU pairing delivers top‑tier efficiency, quiet operation, and intelligent control in a flexible single-zone package. With 21 SEER2/9.1 HSPF2 ratings, smart connectivity, and rugged durability, it caters equally to tech‑savvy homeowners, busy contractors, and savvy property managers. Its scalable, space-saving design and reliable performance help HVAC365 partners address residential and light-commercial applications with confidence and value.
