Description

Pioneer Quantum Ultra 4-Zone 36K BTU Heat Pump System is a complete 4-zone ductless mini split heat pump package for independent room-by-room comfort. This Quantum Ultra bundle pairs one outdoor condenser with four 9,000 BTU 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

  • Multi-zone comfort: heat or cool 4 separate areas while giving each indoor unit its own wireless remote and dedicated line-set selection.
  • High-efficiency inverter performance: rated at 22.5 SEER2 / 12.0 EER2 for cooling and 9.5 HSPF2 / 3.5 COP2 for heating, with variable-speed inverter compressor and fan technology designed to reduce energy use and temperature swings.
  • 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.
  • Clean wall-mounted design: high-wall indoor sections keep floor space open while delivering quiet, direct comfort where each zone needs it.

Line-set options

Choose a line-set length for each indoor air handler before adding to cart. Available choices are None, 10 Ft, 16 Ft, 25 Ft, 33 Ft, and 50 Ft. For this four-zone product, the final selector pairs air handlers #3 and #4 so every line-set combination remains available. If your total combined line-set length is longer than the factory pre-charge allowance, the installing technician may need to add refrigerant according to the installation manual.

Installation note

This is a ductless heat pump system that should be sized, installed, evacuated, leak-tested, and commissioned by a qualified HVAC professional according to local code and Pioneer installation instructions.
