How much does the Pelonis PAT10H2KWT cost to run?

About 16¢ an hour of cooling, or $38.35 for 30 days at 8 hours a day (less once the compressor cycles off).

DOE's record lists 880 W of electrical input 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 7¢.

How does the Pelonis PAT10H2KWT rank in its DOE class?

Its DOE class (through the wall ACs, 8,000 to 10,999 BTU/h) has 38 models certified to DOE. Its CEER of 14.1 is tied for 1st of the 38, and level with their median of 14.1.

Questions

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 Pelonis PAT10H2KWT cost to run for 8 hours?
About $1.28 for 8 hours of cooling: roughly 880 W at 18.16¢/kWh, the US residential average for August 2026 (EIA).
