Pioneer’s 24,000 BTU Quantum Ultra ceiling cassette mini-split delivers efficient cooling and heating without taking up wall space. Designed for mid-size commercial suites, open-concept offices, and large residential areas, this ductless air-conditioning system pairs inverter technology with a discreet four-way cassette for year-round comfort.

The split-system design positions the quiet indoor grille in the ceiling while the outdoor condenser handles heavy lifting, giving you flexible placement and clean lines in spaces up to 1,000 square feet.

Key Features and Benefits of the Pioneer 24,000 BTU Quantum Ultra Ceiling Cassette Mini-Split

  • 360-Degree Airflow: The 8-way directional louvers supply air in every direction, eliminating hot and cold spots across your entire space.
  • High Efficiency: This model has a 22.5 SEER2 rating for cooling and an 8.4 HSPF2 rating for heating, lowering energy use and reducing operating costs during long cooling seasons.
  • Heat Pump Operation: Reverse-cycle heat pump operation supplies up to 25,000 BTU of heat, keeping the space comfortable even when outdoor temperatures dip.
  • Built-In Drain Pump: The integrated condensate pump can lift water up to 30 inches, simplifying drainage in drop ceilings. It has an automatic shut-off function if it detects a clog in the line. 
  • Adaptive Distribution: Smart sensors adjust vane position based on room demand, so you spend less time on manual tweaks.
  • Fresh-Air Intake: A dedicated fresh air intake port allows limited outdoor air introduction for ventilation code compliance.
  • Low Noise: Operating at less than 54 dB, the cassette blends into offices, clinics, and classrooms without distraction.
  • Washable Filters: Slide-out mesh filters can be washed clean in minutes, supporting consistent airflow and lowering maintenance costs.
  • R-454B Refrigerant: A refrigerant with a lower global warming potential aligns with efficiency goals and building regulations.
  • Lineset Options: You can choose this mini-split with no line set, or with a 16, 25, 33, or 50-foot line set.

Note: Professional installation is required for this mini split model. 

Low-Profile Ceiling Design

Choosing a cassette mini-split frees your walls for shelving, artwork, or a minimalist look while still providing zoned climate control. The 33-inch square grille fits neatly between standard joists and can recess into most suspended ceiling grids. This layout is especially helpful when retrofitting older buildings where ductwork is impractical but aesthetics remain a priority. By circulating air from the center of the room, the cassette's Intelligent Air Throw technology minimizes draft complaints often linked with wall-mounted indoor heads.

Sylvane’s Expert Take

If you need powerful, energy-saving performance without visible wall equipment, Pioneer’s Quantum Ultra cassette is a solid choice. The high SEER2 rating, built-in drain pump, and 360-degree discharge make installation straightforward and daily use hands-off. Add the heat-pump mode and optional fresh-air intake, and you have a flexible solution for mixed-use spaces that sees use year-round.

For customers needing a mini-split that balances efficiency, quiet operation, and code-friendly features, the Quantum Ultra Ceiling Cassette mini-split checks every box.
