TCL H6W4KW

The TCL H6W4KW is certified at 329 kWh per year (based on 750 standardized hours), roughly $60 at the national average — though seasonal use means your real bill lands in a few months, not twelve. That puts it in the most efficient tenth of every certified room air conditioner — 38% less electricity than the median, ranked 24 of 439. The same unit costs $43 a year in Nevada but $173 in Hawaii — electricity rates, not the appliance, make the difference.
