How we know it's one unit
Every brand here filed its model numbers under the same DOE basic model, HAC904. 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 4 brands file HAC904 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 HAC904.
How much does the HAC904 cost to run?
10,000 BTU/h SACC divided by a CEER of 7.9 is about 1,266 W while cooling. That's about 23¢ an hour, or $55.17 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 HAC904, and is it the same under every brand?
- Who makes the GrowthWing HAC904?
- DOE's records don't say. The GrowthWing HAC904 is filed under basic model HAC904 along with 3 other brands. All of them file that same number as their model, and DOE's database has no manufacturer field.
- Is the GrowthWing HAC904 the same as the ECOSELF HAC904?
- Yes, by DOE's records. Both are filed under basic model HAC904 and list the same certified figures: 10,000 BTU/h SACC, CEER 7.9 and single hose.
- Which brand of HAC904 is cheapest to run?
- They tie: every brand files 10,000 BTU/h SACC, CEER 7.9 and single hose, so each costs about 23¢ an hour to run while cooling.
