How much does the LG LW6027 cost to run?

About 11¢ an hour of cooling, or $25.28 for 30 days at 8 hours a day (less once the compressor cycles off).

DOE's record lists 580 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 5¢.

How does the LG LW6027 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 14.3 is tied for 14th of the 45, and 4% above their median of 13.7.

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 LW6027 cost to run for 8 hours?
About 84¢ for 8 hours of cooling: roughly 580 W at 18.16¢/kWh, the US residential average for August 2026 (EIA).
