How efficient are AUX portable ACs?
Of the 2 AUX portable ACs, none files a higher CEER than the class median: 2 fall below it.
| Class | AUX models | Above median | Class median | Best AUX |
|---|---|---|---|---|
| Single hose portable ACs (1,044) | 2 | 0 | CEER 7.3 | APACM08V1 CEER 7.2 |
A higher CEER means more cooling per watt.
Who makes AUX portable ACs?
DOE's database has no manufacturer field, so the evidence is whose model number each unit is filed under and which other brands file the same unit.
None of the 2 AUX basic models is filed by another brand as of 2026-11-03, and none uses another company's model number. DOE's records tie them to AUX alone.
How much does an AUX portable AC cost to run?
While cooling, AUX portable ACs draw about 923 to 1,111 W (certified SACC divided by CEER). That's 17¢ to 20¢ an hour, or $40.23 to $48.43 for 30 days at 8 hours a day. The lowest is AUX A039-10K (6,000 BTU/h SACC, CEER 6.5) and the highest AUX APACM08V1 (8,000 BTU/h SACC, CEER 7.2).
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.
