Indoor operation stays quiet: at its lowest fan speed, the air handler runs at approximately 18.5 dB(A), making it suitable for noise-sensitive spaces like bedrooms or study rooms. Outdoor noise remains modest (~53.5 dB(A) at high fan speed), offering a balance between performance and subtlety. Additional conveniences include sleep mode, refrigerant-leak detection, auto-restart, and built-in smart-home integration via the manufacturer’s app, with voice-assistant support for hands-free control.

Whether you’re adding climate control to an existing space or outfitting a new room, this mini-split system delivers a robust mix of comfort, efficiency, and convenience — all in a compact, wall-mounted design suitable for modern homes.
