About Fujitsu HVAC Systems
Fujitsu General is a subsidiary of Fujitsu Limited that makes HVAC equipment, primarily ductless mini-split and multi-zone systems. In North America, Fujitsu is one of the top-selling mini-split brands alongside Mitsubishi and Daikin. The company has been making air conditioning equipment since the 1950s. There's a genuine limitation here: Fujitsu does not encode the manufacture date in the serial number the way most brands do. The serial identifies the unit and production run, but not the date. Enter your serial number above and the AI model lookup will attempt to identify your unit's manufacture period from available records. This works for many models, though it's less precise than a direct serial number decode.
