How much does the Antarctic Star AC7207-7K cost to run?

About 18¢ an hour of cooling, or $44.22 for 30 days at 8 hours a day (less once the compressor cycles off).

7,000 BTU/h SACC divided by a CEER of 6.9 is about 1,014 W while cooling. Electricity at 18.16¢/kWh, the US residential average for August 2026 (EIA Electric Power Monthly, table 5.6.A). Each 1¢/kWh you pay above or below 18.16¢ moves the 8 hour figure by 8¢.

How does the Antarctic Star AC7207-7K rank in its DOE class?

In its DOE class (single hose portable ACs), 171 models have a matched Amazon listing. Its CEER of 6.9 is tied for 113th of the 171, and 5% below their median of 7.3. On cost, the same 7,000 BTU/h at their median CEER would cost about $41.79 for 30 days at 8 hours, $2.42 less than this one.

Questions

What is the Antarctic Star AC7207-7K's real BTU?
It's certified to DOE at 7,000 BTU/h SACC (seasonally adjusted cooling capacity), the rating DOE requires for portable ACs. A box figure labeled ASHRAE is usually higher for the same unit because it comes from a different test: SACC vs ASHRAE.
Is it single hose or dual hose?
It was tested as a single hose unit, per the DOE record.
How big a room does it cool?
About 300 sq ft. ENERGY STAR's sizing chart calls for 7,000 BTU/h in rooms up to 300 sq ft. A sunny room, a kitchen or a high ceiling needs more.
How much does the Antarctic Star AC7207-7K cost to run for 8 hours?
About $1.47 for 8 hours of cooling: roughly 1,014 W at 18.16¢/kWh, the US residential average for August 2026 (EIA).
Who makes the Antarctic Star AC7207-7K?
DOE's database has no manufacturer field, so the record doesn't say. It does show 6 brands filing one basic model, AM-07B1A3/MAR3-F9: Antarctic Star, Electactic, COWSAR and 3 more.
