Our scoreNot reviewed yetSCORE7.5 / 10
Our takeAn inverter with two separate 7.5 in hoses that route more easily than a hose-in-hose duct, but 10,000 BTU SACC, CEER 12.1 and no heat. We don't link it: the only Amazon offer we found was used.The 2026 10,000 BTU U at CEER 16, ENERGY STAR Most Efficient and not recalled. Little owner history yet.

Watch out forWarranty is 1 year plus 3 years on the compressor, but service is mail-in, only within the 48 contiguous states, needs an authorized Whynter dealer, and you pay return freight after month two. ARC-1280MX is the black version of the same unit. Whynter's warranty excludes units bought from unauthorized resellers.U1KWT and the recalled U1QWT differ by one letter (K vs Q).
