How we know it's one unit

Every brand here filed its model numbers under the same DOE basic model, A5406-10K-CH. 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 10 brands file A5406-10K-CH 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 A5406-10K-CH.

How much does the A5406-10K-CH cost to run?

6,000 BTU/h SACC divided by a CEER of 6.6 is about 909 W while cooling. That's about 17¢ an hour, or $39.62 for 30 days at 8 hours a day.

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.
