Our takeThe 2026 revision of the 8,000 BTU U, re-rated at 7,800 BTU and CEER 15.1. Not recalled; check the label, because the model number still says 08.The 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.

Watch out forU1KWT and the recalled U1QWT differ by one letter (K vs Q).Windmill'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.
