Our takeThe Windmill to buy if you want one: an inverter box unit at CEER 15 and 41 dBA on low. A rough owner record and a one-year warranty are why we'd buy a Midea U or an LG Dual Inverter first.The window unit we'd put in a bedroom first: inverter, compressor outside the glass, CEER 15 and a suffix that isn't recalled. Skip it if your window is short or you need heat; no U has a heat mode.

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. 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. When we checked in October 2026 this listing had no featured offer, only a third-party seller. Comfort Sense (remote sensor) fixes the built-in sensor's wrong room reading.
