Overview
The 9,000 Btu/h Cooper&Hunter Astoria Wall Mounted Mini Split is a single/multi-zone indoor unit built for efficient, flexible comfort using eco-friendly R454B refrigerant. Rated up to 25.8 SEER2 in multi-zone configuration, it pairs with either regular (-13°F) or Hyper (-22°F) rated outdoor condensers, making it a strong fit across a wide range of climates.
The unit's E-Box and PCB sit behind a front-mounted cover kickstand for quick access, and the blower wheel lifts out easily for cleaning or service. TU1 copper tubing supports long-term durability and efficient heat transfer, while a larger air inlet and outlet improve airflow and help distribute temperature more evenly across the room.
