How we know it's one unit
Every brand here filed its model numbers under the same DOE basic model, KOW60A. DOE's definition of a basic model (10 CFR 430.2) covers "all units of a given type of covered product (or class thereof) manufactured by one manufacturer" with "the same primary energy source" and nearly identical "electrical, physical, and functional (or hydraulic) characteristics that affect energy consumption, energy efficiency, water consumption, or water efficiency." So one set of DOE figures covers every name on the list. 4 of the brands file KOW60A itself as their model number, so the number alone doesn't say which of them builds it.
Brands may still differ in color, controls, accessories, warranty and support. Full record and every model number: waykar KOW60A.
How much does the KOW60A cost to run?
4,500 BTU/h SACC divided by a CEER of 5.9 is about 763 W while cooling. That's about 14¢ an hour, or $33.24 for 30 days at 8 hours a day. The filings differ, so the cost does too: lowest for Foshan Hanyang (8¢ an hour), highest for 4 brands (14¢ an hour).
At 18.16¢ per kWh, the US average residential price for August 2026 (EIA Electric Power Monthly, table 5.6.A). Worked out from the certified figures.
