How we know it's one unit

Every brand here filed its model numbers under the same DOE basic model, HAC-901. 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 3 brands file HAC-901 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: ECOSELF HAC-901.

How much does the HAC-901 cost to run?

8,000 BTU/h SACC divided by a CEER of 7.3 is about 1,096 W while cooling. That's about 20¢ an hour, or $47.76 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 HAC-901, and is it the same under every brand?

Who makes the KoolSiln HAC-901?
DOE's records don't say. The KoolSiln HAC-901 is filed under basic model HAC-901 along with 2 other brands. All of them file that same number as their model, and DOE's database has no manufacturer field.
Is the KoolSiln HAC-901 the same as the ECOSELF HAC-901?
Yes, by DOE's records. Both are filed under basic model HAC-901 and list the same certified figures: 8,000 BTU/h SACC, CEER 7.3 and single hose.
Which brand of HAC-901 is cheapest to run?
They tie: every brand files 8,000 BTU/h SACC, CEER 7.3 and single hose, so each costs about 20¢ an hour to run while cooling.
