How we know it's one unit

Every brand here filed its model numbers under the same DOE basic model, KC-35/YXRDBp(E1/6)(080737). 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. TCL files KC-35/YXRDBp(E1/6)(080737) itself as one of its model numbers. The other brand files under it with its own numbers.

Brands may still differ in color, controls, accessories, warranty and support. Full record and every model number: TCL KC-35/YXRDBp(E1/6)(080737).

How much does the KC-35/YXRDBp(E1/6)(080737) cost to run?

DOE's record lists 1,140 W of electrical input while cooling. That's about 21¢ an hour, or $49.69 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 Whirlpool WHAW121CWX?
The Whirlpool WHAW121CWX is filed with DOE under basic model KC-35/YXRDBp(E1/6)(080737), which is TCL's own model number. That makes TCL the filer of record, though DOE's database has no manufacturer field to say who builds it.
Is the Whirlpool WHAW121CWX the same as the TCL KC-35/YXRDBp(E1/6)(080737)?
Yes, by DOE's records. Both are filed under basic model KC-35/YXRDBp(E1/6)(080737) and list the same certified figures: 12,000 BTU/h, CEER 16 and 1,140 W.
Which brand of KC-35/YXRDBp(E1/6)(080737) is cheapest to run?
They tie: every brand files 12,000 BTU/h, CEER 16 and 1,140 W, so each costs about 21¢ an hour to run while cooling.
