Our takeThe December 2024 12,000 BTU U at CEER 15.2, not recalled. Hard to find; the current V1UWT is the easier buy.The portable we'd buy: hose-in-hose inverter, 12,000 BTU SACC, a published CEER of 14.2 and a heat pump. The catch is the mail-in warranty and an authorized-dealer requirement.

Watch out forMidea sold the U2QWT and the recalled U1QWT with the same CEER ratings and near-identical titles; one digit separates them.Warranty 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. Portable ACs are excluded from ENERGY STAR's room AC program. ARC-1230WN and ARC-1230WN2 are similar inverter models with no heat.
