Fujitsu General: AIRSTAGE Heat Pump Innovation
Fujitsu General America, Inc., headquartered in Fairfield, New Jersey, brings Japanese precision engineering to the North American HVAC market through its AIRSTAGE brand of heat pump systems. As a subsidiary of Fujitsu General Limited, the company leverages decades of heat pump research and development to deliver some of the most efficient and reliable mini-split, multi-zone, and VRF systems available.
Fujitsu General is particularly recognized for pioneering XLTH (Extra Low Temperature Heating) technology, which enables their heat pumps to maintain heating output at temperatures as low as -15°F — making them one of the best-performing cold climate heat pump solutions on the market.
AIRSTAGE Product Lines
Single-Room Mini-Split Systems
Fujitsu's ductless mini-split systems offer targeted heating and cooling for individual rooms. Available in wall-mounted, floor-mounted, and slim-duct configurations with XLTH cold climate capability and SEER2 ratings up to 33.
Multi-Room Systems
AIRSTAGE multi-room systems connect up to 8 indoor units to a single outdoor unit, providing zoned comfort for larger homes. Each zone is independently controlled for personalized comfort throughout the home.
Central Heat Pump Systems
For homes with existing ductwork, Fujitsu offers central ducted heat pump systems that provide whole-home heating and cooling through a conventional duct system with the efficiency of inverter technology.
Commercial VRF Systems
AIRSTAGE VRF (Variable Refrigerant Flow) systems provide efficient heating and cooling for commercial buildings of all sizes, with heat recovery capability for simultaneous heating and cooling in different zones.
Cold Climate Performance
Fujitsu's XLTH technology is a standout feature that makes their heat pumps viable primary heating sources in cold climates. The technology maintains heating capacity at extreme low temperatures where many competitors' systems significantly lose output. This cold climate capability makes Fujitsu systems excellent candidates for integration with geothermal ground loops in hybrid system configurations.
