How we know it's one unit

Every brand here filed its model numbers under the same DOE basic model, PC9R-AME. 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. Both brands file PC9R-AME 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: air master PC9R-AME.

How much does the PC9R-AME cost to run?

9,250 BTU/h SACC divided by a CEER of 7.6 is about 1,217 W while cooling. That's about 22¢ an hour, or $53.05 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 PC9R-AME, and is it the same under every brand?

Who makes the SereneLife PC9R-AMB?: DOE's records don't say. The SereneLife PC9R-AMB is filed under basic model PC9R-AME along with the air master PC9R-AMB. Both brands file that same number as their model, and DOE's database has no manufacturer field.
Is the SereneLife PC9R-AMB the same as the air master PC9R-AMB?: Yes, by DOE's records. Both are filed under basic model PC9R-AME and list the same certified figures: 9,250 BTU/h SACC, CEER 7.6 and single hose.
Which brand of PC9R-AME is cheapest to run?: They tie: every brand files 9,250 BTU/h SACC, CEER 7.6 and single hose, so each costs about 22¢ an hour to run while cooling.
