How much does the LG LW6023IVSM cost to run?

About 9¢ an hour of cooling, or $22.23 for 30 days at 8 hours a day (less once the compressor cycles off).

DOE's record lists 510 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 4¢.

How does the LG LW6023IVSM rank in its DOE class?

Its DOE class (window ACs, 6,000 to 7,999 BTU/h) has 45 models certified to DOE. Its CEER of 15.5 is 1st of the 45, and 13% above their median of 13.7. On cost, the same 6,000 BTU/h at their median CEER would cost about $25.15 for 30 days at 8 hours, $2.92 more than this one.

Questions

How big a room does it cool?
About 250 sq ft. ENERGY STAR's sizing chart calls for 6,000 BTU/h in rooms up to 250 sq ft. A sunny room, a kitchen or a high ceiling needs more.
How much does the LG LW6023IVSM cost to run for 8 hours?
About 74¢ for 8 hours of cooling: roughly 510 W at 18.16¢/kWh, the US residential average for August 2026 (EIA).
