Info & Guides

The Pioneer 18,000 BTU Dual Zone Quantum Ultra Mini-Split Heat Pump delivers targeted, year-round climate control for two separate rooms or zones. Built around inverter technology and a cold-climate rated heat pump, it balances high efficiency with dependable performance in residential and light-commercial spaces.

This ductless mini-split pairs an outdoor compressor unit with two 9,000 BTU wall-mounted air handlers, giving you independent temperature control without the need for ductwork. The result is precise comfort, easy installation, and energy-conscious operation.

Key Features and Benefits of the Pioneer 18,000 BTU Dual Zone Quantum Ultra Mini-Split

Dual-Zone Flexibility: Heat and cool two separate 350-square-foot spaces with two 9,000 BTU air handlers and a 20,000 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 ratings lower 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-inch line sets required for proper installation.

Year-Round Comfort

This Pioneer mini-split heat pump is engineered to handle serious temperature swings. Cooling performance remains steady in outdoor conditions up to 131 degrees F, while the low-ambient heating feature tackles sub-zero cold snaps down to -13 degrees F. Whether you're offsetting the heating and cooling load in a bedroom and office or delivering supplemental heat to a finished basement, the system maintains consistent comfort without needing traditional HVAC equipment and ducting.

Installation is straightforward for qualified professionals, and the R-454B refrigerant lowers your energy use.
