Our scoreNot reviewed yetSCORE7.5 / 10
Our takeThe unit made for a 27 in sleeve, with an inverter that runs down to 5,000 BTU and two years of parts and labor. ENERGY STAR lists this B model at CEER 14.2, which clears DOE's 2026 bar for its class.The 2026 10,000 BTU U at CEER 16, ENERGY STAR Most Efficient and not recalled. Little owner history yet.

Watch out forThe wrong rear grille or a missing baffle kit in a 19-3/4 in deep sleeve recirculates hot air and may lead to early compressor failure, per Friedrich. The Amazon listing we found is the older WCVT10B10A; we link Friedrich's current line.U1KWT and the recalled U1QWT differ by one letter (K vs Q).
