| Install | Two separate 5.9-inch hoses (intake and exhaust) each stretch to about 60 inches and connect to a plastic dual-port window kit that adjusts roughly 20 to 46 inches; the two-hole panel is bulkier in the window than single-hose kits. It fits hung and slider windows, and Whynter sells extension panels for taller sliders. Auto-drain technology recycles condensate into the exhaust in cooling mode, so most owners never touch the drain plug outside dehumidifier duty in humid climates. Detachable hoses make off-season storage easier than the Midea's fixed duct. | Like the Midea Duo it shares a platform with, the ARC-1230WN uses a permanently attached hose-in-hose duct with a sealed base that telescopes to about 48 inches, feeding a multi-panel window kit that covers roughly 20 to 48 inch hung and slider windows. Cooling mode is auto-drain self-evaporative, so condensate exits with the exhaust; connect the drain hose only for dehumidify mode or extreme humidity. At 73 pounds it rolls well but favors a permanent summer spot over room-to-room duty. |
