Product overview
Pioneer Quantum Ultra 33,000 BTU 3-zone heat pump system is a mixed-capacity ductless mini split package for independent room-by-room comfort. This bundle pairs one YN030GLSI24M3G outdoor condenser with 9K + 12K + 12K wall-mounted indoor air handlers, giving homes, additions, offices, and light commercial spaces efficient cooling and heating from one matched system.
Why this system works well
- Balanced mixed-zone sizing: combines 9K + 12K + 12K indoor capacities for layouts with small, medium, and larger rooms instead of forcing three identical zones.
- Published compatibility: the YN030GLSI24M3G condenser supports 9K, 12K, 18K, and 24K compatible Quantum Ultra wall-mounted indoor sections, with connected indoor capacity up to 36,000 BTU.
- High-efficiency inverter performance: rated at 24 SEER2 / 12.0 EER2 for cooling and 10.5 HSPF2 IV / 8.8 HSPF2 V for heating, with variable-speed inverter operation for steadier comfort.
- Cold-weather heating: the ultra low-ambient design can deliver heat at outdoor temperatures down to -13°F, helping the system serve as a year-round comfort solution.
- Smart operation: Wi-Fi enabled controls and included wireless remotes make it easy to adjust each zone.
