Our takeThe 2026 12,000 BTU U at CEER 16, ENERGY STAR Most Efficient and not recalled. Little owner history yet.For a wide window, 27-39 in with a 16 in opening, and a room up to 550 sq ft: CEER 15 and in-home warranty service. It weighs 85 lb, so plan on two people for the install.

Watch out forU1KWT and the recalled U1QWT differ by one letter (K vs Q).LG's 1-year warranty applies only when bought from an LG authorized dealer; ask a third-party seller. LG lists the same 1,020 W / 9.1 A for this and the 8,500 BTU model; treat the electrical figure as unconfirmed.
