Our takeAn inverter box unit at CEER 15 that weighs 63 lb against GE's 80, for rooms near 450 sq ft. Check your opening height; Windmill needs 14 in.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 forWindmill's warranty is one year on every size, with no longer compressor term, and owners report control-board and stop-cooling failures. Windmill sells a non-inverter Original and a budget Lite line under the same name; confirm the model number on the box.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.
