Our scoreNot reviewed yetSCORE7.5 / 10
Our takeSame job as the Midea, with a published 7,000 BTU heat pump rating and a year of parts and labor. It's a spec-sheet pick: we've seen no owner reports, and the heat still stops below 41°F.The December 2024 U revision, not recalled, at CEER 16 with ENERGY STAR Most Efficient status. About 6% less power than the CEER 15 V1UWT for the same cooling, which is nice but not worth chasing a hard-to-find listing.

Watch out forKeystone calls the heat supplemental, not a primary heat source.Midea sold the U2QWT and the recalled U1QWT with the same CEER ratings and near-identical titles; one digit separates them.
