Our scoreSCORE6.9 / 10SCORE5.9 / 10
Our takeThe bigger sibling of our window heat pump pick, with the same 41°F heat floor. Its CEER 13.3 is below DOE's 14.4 minimum for units made from May 26, 2026, and we found no new Amazon listing.Amana's R-32 heat-pump PTAC: EER 11.5, 11,000 BTU/h of heat pump output and a 3.5 kW strip. Worth it when you're replacing an Amana with a thermostat already on the wall; otherwise the Distinctions costs less.

Watch out forOwners report a rattle or a loud start in heat mode, loud enough to wake some at night. Midea's app wouldn't connect for some owners.Warranty is 5-year limited, but years 2-5 cover functional parts only (no labor) and labor needs an authorized PTAC servicer; faulty installation is excluded. No control pad on the unit; a wired wall or Amana wireless thermostat is required. Amana's K-series (PTH123K) is the older R-410A platform with different ratings.
