Our takeThe most efficient small window unit we cover, CEER 15.5 and ENERGY STAR Most Efficient, in a box chassis. Owners who had both reported its compressor whine less often than the Midea U's; Amazon had no offers, so buy it from LG.A 2026 6,000 BTU U at CEER 15.1 with ENERGY STAR Most Efficient status and a 3-year warranty on Midea's store. Not recalled; we found no Amazon listing to link.

Watch out forLG's 1-year warranty applies only when bought from an LG authorized dealer; ask a third-party seller. The Amazon listing B0CL1DJPZ8 had no offers when we checked; we link LG's own store.The U1QWT suffix is recalled in the 8,000-12,000 BTU sizes; this 6,000 BTU U1QWT is not.
