Our takeThe cooling-only 14,000 BTU Duo, 12,000 BTU SACC, for a hot top-floor room or a studio. Same hose-in-hose duct and inverter as the heat model.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 for1-year warranty; the owner pays diagnostics, removal, transport and reinstallation for service. Midea's US page for the -A version lists Heat: No but mentions heat under comfort features; it doesn't heat.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.
