How much does the Whynter ARC-122DHP 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 Whynter ARC-122DHP rank in its DOE class?

In its DOE class (dual hose portable ACs), 34 models have a matched Amazon listing. 33 of them have a higher CEER than its 6.9, which is 46% below their median of 12.8. On cost, the same 7,000 BTU/h at their median CEER would cost about $23.84 for 30 days at 8 hours, $20.38 less than this one.

Questions

What is the Whynter ARC-122DHP'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 dual 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 Whynter ARC-122DHP 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).
