AUX AIR USA, a subsidiary of the global HVAC leader AUX, has announced the launch of its One-Way Cassette, a compact ductless air conditioning system tailored for tight ceiling applications and modern interiors. Set to be available in the U.S. starting July 2026, this innovative unit is designed to fit seamlessly between 14-inch joist spacing, making it an ideal solution for spaces where traditional wall-mounted or ducted systems may not be feasible. The One-Way Cassette is particularly suitable for bedrooms, hallways, home offices, and multifamily units, preserving ceiling height while maintaining a sleek architectural appearance. It comes in three capacities—9K, 12K, and 18K BTU—and includes features like built-in Wi-Fi control, a washable filter, and a high-lift condensate pump capable of a 57-inch lift. Additionally, the system offers a slide-out PCB control box for easy maintenance, allowing contractors to service the unit without removing it from the ceiling. John McGaughey, Vice President of Sales at AUX AIR USA, highlighted the product's role in addressing installation challenges faced by contractors, providing both flexibility and aesthetic appeal for homeowners.
