TCL H10W4MW
The TCL H10W4MW is certified at 500 kWh per year (based on 750 standardized hours), roughly $94 at the national average — though seasonal use means your real bill lands in a few months, not twelve. Efficiency-wise it's unremarkable in a good way: within 6% of the median certified room air conditioner (rank 183 of 396). Where you live moves the bill from $62 a year in North Dakota to $233 in Hawaii.
