How we know it's one unit

Every brand here filed its model numbers under the same DOE basic model, A4208K-WHITE. 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. All 17 brands file A4208K-WHITE 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: Antarctic Star A4208K-WHITE.

How much does the A4208K-WHITE cost to run?

8,300 BTU/h SACC divided by a CEER of 10.7 is about 776 W while cooling. That's about 14¢ an hour, or $33.81 for 30 days at 8 hours a day. The filings differ, so the cost does too: lowest for 16 brands (14¢ an hour), highest for Xbeauty (15¢ 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.
