Pioneer® Quantum Ultra™ 18,000 BTU 21 SEER2 230V Ceiling Concealed Ducted Mini-Split Air Conditioner Inverter Heat Pump Full Set

For HVAC professionals and business owners who demand top-tier efficiency and quiet, seamless comfort, the Pioneer Quantum Ultra 18,000 BTU ceiling concealed ducted mini-split heat pump offers a perfect balance of power and discretion. Designed specifically for spaces between 500 and 750 square feet, this system delivers strong cooling and heating performance while remaining virtually invisible within the ceiling, making it an excellent choice for commercial offices, retail environments, or upscale residential applications.

Superior Energy Efficiency and Reliable Comfort

With a cooling capacity of 17,000 BTU and heating capacity of 18,000 BTU, this unit provides consistent comfort without overworking. The standout 21 SEER2 and 8.1 HSPF2 ratings mean your customers benefit from lower energy bills and reduced environmental impact. The variable-speed DC inverter compressor precisely adjusts its output to the load, delivering smooth, efficient operation that reduces wear and tear and keeps noise levels low.

Precharged with eco-friendly R454b refrigerant, this system supports sustainable installations while maintaining excellent performance. It functions reliably in a wide temperature range—from as low as 5°F in heating mode up to 131°F in cooling mode—making it adaptable to diverse climates.

Discreet Design with Balanced Airflow

The ceiling concealed indoor unit stays out of sight, preserving the aesthetics of any room. Motorized dual-axis louvers provide precise airflow control, moving up/down and left/right to ensure even temperature distribution and eliminate hot or cold spots. Dual drainage ports simplify condensate management during installation and maintenance, saving you time on the job.

Washable, reusable air filters help maintain clean indoor air and reduce ongoing maintenance costs, keeping your customers satisfied long after the install.

User-Friendly Controls and Smart Features

The included remote control offers multiple modes tailored to real-life needs. ECO and SLEEP modes conserve energy during low-demand periods, while TURBO mode rapidly ramps up cooling or heating when quick comfort is needed. The SELF-CLEAN cycle helps keep the system running efficiently by reducing dust buildup. MEMORY function stores preferred settings for easy recall, and IFEEL technology senses local temperature to automatically fine-tune system operation.
