Technical foundation: Manufacturer low-fan sound ratings on premium ductless heads land at 19 dBA on the Mitsubishi MSZ-FS06NA (6,000 BTU/h), 19 dBA on the Daikin Quaternity FTXG09HVJU (9,000 BTU/h), and 21 dBA on the Fujitsu Halcyon ASU9RLF1. ASHRAE NC 25–30 for sleeping spaces translates to roughly 30–35 dBA broadband; a 19 dBA indoor head clears it with margin when wall coupling is isolated. R-32 refrigerant dominates new ductless platforms (Daikin, Mitsubishi, Fujitsu) — about 30% less charge by mass than R-410A for equivalent capacity, A2L safety class.
