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 size step for a primary bedroom or living room of 400-450 sq ft, with the same closed-sash quiet as the 8,000. Too big for a typical bedroom, where it cools fast and leaves the air damp.

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.CPSC recall #25320 (June 2025) covers the 8,000-12,000 BTU V1QWT, AV1QWT, W1QWT and U1QWT Midea U models over mold from pooled water. Read the suffix on the listing and again on the box label. The recalled 10,000 BTU listing (MAW10V1QWT) is still on Amazon; this one is MAW10V1UWT. Owners of earlier U models report a high-pitched inverter whine some people hear and others don't; buy where returns are easy and run it overnight on low fan in week one.
