How we know it's one unit

Every brand here filed its model numbers under the same DOE basic model, A5405-8K. 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 A5405-8K 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 A5405-8K.

How much does the A5405-8K cost to run?

5,000 BTU/h SACC divided by a CEER of 6.2 is about 806 W while cooling. That's about 15¢ an hour, or $35.15 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.

Who makes the A5405-8K, and is it the same under every brand?

Who makes the COWSAR A5405-8K?: DOE's records don't say. The COWSAR A5405-8K is filed under basic model A5405-8K along with 9 other brands. All of them file that same number as their model, and DOE's database has no manufacturer field.
Is the COWSAR A5405-8K the same as the Antarctic Star A5405-8K?: Yes, by DOE's records. Both are filed under basic model A5405-8K and list the same certified figures: 5,000 BTU/h SACC, CEER 6.2 and single hose.
Which brand of A5405-8K is cheapest to run?: They tie: every brand files 5,000 BTU/h SACC, CEER 6.2 and single hose, so each costs about 15¢ an hour to run while cooling.
