| Install | The permanently attached hose-in-hose duct telescopes from 13 to 48 inches, and the five-panel window kit spans roughly 20 to 48 inches without cutting, with generous weather stripping included. It works in hung and sliding windows; sliding glass doors need a third-party tall panel. In cooling mode the unit is self-evaporative and exhausts moisture automatically — you only break out the included drain hose in very humid climates or dehumidify mode. Budget help for stairs: it's a bulky 75-pound tower. | Single 5-inch exhaust hose extends to about 4.9 feet and connects to LG's easy-install window kit for hung and slider windows around 18 to 50 inches; the longer-than-average hose gives more placement freedom than the Midea/Whynter fixed ducts. LG's auto-evaporation system minimizes drainage in cooling mode — most owners only drain for dehumidify (Dry) mode via the rear port. At 69 pounds with smooth casters it's among the easier premium units to reposition, and the auto-swing vent spreads air without aiming. |
