Wallmaster WHVT14B33B

The Wallmaster WHVT14B33B is certified at 838 kWh per year (based on 750 standardized hours), roughly $158 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 58% more than the median room air conditioner (rank 342 of 396) — so the state you live in matters more than usual. Where you live moves the bill from $103 a year in North Dakota to $391 in Hawaii. It also meets ENERGY STAR's stricter “Most Efficient” criteria.
