TCL H24W4KW-CA

The TCL H24W4KW-CA is certified at 1,417 kWh per year (based on 750 standardized hours), roughly $267 at the national average — though seasonal use means your real bill lands in a few months, not twelve. It sits near the bottom of the certified table — using 166% more than the median room air conditioner (rank 388 of 396) — so the state you live in matters more than usual. The same unit costs $175 a year in North Dakota but $661 in Hawaii — electricity rates, not the appliance, make the difference.
