How much does the Sea Breeze PADH312M cost to run?
About 20¢ an hour of cooling, or $48.97 for 30 days at 8 hours a day (less once the compressor cycles off).
10,000 BTU/h SACC divided by a CEER of 8.9 is about 1,124 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 9¢.
How does the Sea Breeze PADH312M rank in its DOE class?
In its DOE class (dual hose portable ACs), 34 models have a matched Amazon listing. 31 of them have a higher CEER than its 8.9, which is 30% below their median of 12.8. On cost, the same 10,000 BTU/h at their median CEER would cost about $34.05 for 30 days at 8 hours, $14.92 less than this one.

Questions
- What is the Sea Breeze PADH312M's real BTU?
- It's certified to DOE at 10,000 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 450 sq ft. ENERGY STAR's sizing chart calls for 10,000 BTU/h in rooms up to 450 sq ft. A sunny room, a kitchen or a high ceiling needs more.
- How much does the Sea Breeze PADH312M cost to run for 8 hours?
- About $1.63 for 8 hours of cooling: roughly 1,124 W at 18.16¢/kWh, the US residential average for August 2026 (EIA).
