Key Features and Benefits of the Pioneer 21,000 BTU Dual Zone Quantum Ultra Mini-Split

• Two-Zone Flexibility: Heat and cool two separate 450-square-foot spaces with a 9,000 BTU air handler, a 12,000 BTU air handler, and a 21,000 BTU outdoor compressor, giving you room-by-room temperature control and helping reduce energy waste in unused spaces.
• High Efficiency Operation: This system’s 24 SEER2 cooling rating and 10.0 HSPF2 heating performance lowers operating costs compared with traditional split systems, helping you keep operating costs under budget.
• Pioneer Inverter++ Compressor: This compressor’s patented Pioneer Inverter++ technology automatically scales the output from 30 to 100 percent of capacity as needed, alleviating temperature swings and eliminating the hard start cycles that shorten equipment life.
• Eco-Friendly Refrigerant: This model uses R-454B refrigerant, which has a lower global warming potential compared to legacy blends, supporting sustainability goals and regulatory requirements.
• Quiet Operation: A 58 dB outdoor and 43 dB indoor max noise level minimizes disturbance in living spaces, offices, and patios.
• Wi-Fi Ready Air Handlers: Pair the indoor air handlers with the Pioneer Free Airlink App, Google Assistant, Amazon Alexa, and other third-party voice control apps for remote scheduling, temperature adjustments, and zone monitoring from any smartphone. It also comes with a remote control for each air handler.

Note: This mini-split requires professional installation and does not include the two 1/4 x 3/8″ line sets required for proper installation.

Cold-Climate Ready

Many mini-split air conditioners can’t keep up with heating demands when winter weather sets in. But Pioneer’s Quantum Ultra system maintains a robust 20,000 BTU heating capacity, even when temperatures drop as low as -13 degrees F, by optimizing refrigerant flow and compressor speed. The result is dependable heat without auxiliary strips or backup systems, even in cold-weather regions.

Additionally, this model can cool effectively in temperatures up to 131 degrees F, so you have a versatile climate control solution for locations that experience wide seasonal swings.
