Zone Configuration

The Ramsond RDZ Series 18,000 BTU Dual‑Zone Mini Split System delivers efficient, targeted comfort for multiple rooms at once. Each zone is powered by a dedicated 9,000 BTU wall‑mount indoor unit, ideal for cooling and heating spaces up to 400 sq ft per zone — perfect for kitchens, living rooms, bedrooms, offices, and multi‑room layouts that demand reliable temperature control.

The outdoor condenser arrives fully pre‑charged with environmentally safe R410A refrigerant, engineered for quick installation and dependable performance. Every system includes a 25 ft insulated copper line set kit, allowing flexible placement of each indoor unit without additional charging or complex setup.

With advanced inverter technology, whisper‑quiet operation, and optional Wi‑Fi control, the RDZ Dual‑Zone system provides year‑round comfort, reduced energy consumption, and precise climate control across two separate rooms — all from one compact, high‑efficiency system.
