How this is calculated
  • Annual energy use is the figure ENERGY STAR lists for this model under typical test conditions. It is not measured in your home.
  • Yearly cost = annual kWh × your rate. Monthly cost is the yearly cost divided by 12, a flat average. Five-year cost keeps the rate constant; prices will change.
  • Statewide averages are not your utility’s tariff. Use your bill’s rate for a closer number.
  • We do not estimate watts or hourly cost: the source data does not include them.

Methodology and sources

Model data comes from the ENERGY STAR Certified Room Air Conditioners dataset (EPA). Electricity prices are statewide average residential prices from the U.S. EIA, latest period July 2026. Values are stored locally and refreshed by scheduled imports. Missing values are left blank, never estimated.
