What actually decides it at this size
We have a price for 13 of these units. They span $250 to $570 to buy, median $359 — while the gap between the cheapest and dearest to run is $15 a year. The price gap is about 21× larger. Quietest settings, where the maker publishes one, run 32–45 dBA across 9 of them. So at this size the decision is price and noise. Efficiency is the tiebreak, and the table below ranks on it.

CEER is the DOE room-AC efficiency rating. It decides the running cost — which, at a fixed size, is the smallest of the three numbers that matter here.

Showing the top 20 by CEER. All 73 certified units in this group are filterable in the full product list — we rank here rather than dump, because a table nobody can read is not a resource.
Capacity and efficiency are AHRI-certified values; $/MMBtu is computed by us from EIA energy prices — see methodology. Heat at 5°F is the number that decides whether a heat pump keeps up in real cold, and most listings omit it.
