How much does the Antarctic Star A4208K-WHITE cost to run?

About 14¢ an hour of cooling, or $33.81 for 30 days at 8 hours a day (less once the compressor cycles off). Worked out from the figure most of its filings list.

8,300 BTU/h SACC divided by a CEER of 10.7 is about 776 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 6¢.

How does the Antarctic Star A4208K-WHITE rank in its DOE class?

In its DOE class (single hose portable ACs), 171 models have a matched Amazon listing. 4 of them have a higher CEER than its 10.7, which is 47% above their median of 7.3. On cost, the same 8,300 BTU/h at their median CEER would cost about $49.55 for 30 days at 8 hours, $15.75 more than this one.

Questions

What is the Antarctic Star A4208K-WHITE's real BTU?
It's certified to DOE at 8,300 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 350 sq ft. ENERGY STAR's sizing chart calls for 8,000 BTU/h in rooms up to 350 sq ft. A sunny room, a kitchen or a high ceiling needs more.
How much does the Antarctic Star A4208K-WHITE cost to run for 8 hours?
About $1.13 for 8 hours of cooling, from the figure most of its filings list: roughly 776 W at 18.16¢/kWh, the US residential average for August 2026 (EIA).
Who makes the Antarctic Star A4208K-WHITE?
DOE's database has no manufacturer field, so the record doesn't say. It does show 17 brands filing one basic model, A4208K-WHITE: Antarctic Star, Auseo, COWSAR and 14 more.
