Window AC Price Methodology
Prices are standardized to 1 window air conditioner and expressed in U.S. dollars. The lighter band shows the outer 5th-to-95th-percentile price range. The darker band shows the 25th-to-75th-percentile range. The index line uses our price index formula. The headline range compares the lowest and highest city index values on the latest observation date. Changes in the mix of observed products can also affect the index. Charts can also show lower band, medium band and upper band.
