How we calculate this

Annual energy use (600 kWh a year) is the figure the manufacturer filed for this model with the EPA, in the ENERGY STAR certified product database. Running cost is that figure multiplied by a state's average residential electricity price from the U.S. Energy Information Administration (12-month average through July 2026, average revenue per kWh).

The annual figure for a room air conditioner assumes 750 hours of cooling a year, per the DOE test procedure (10 CFR 430 Subpart B, Appendix F, §5.2.1). Full methodology.
