K�hl KCVM18B30B

The K�hl KCVM18B30B is certified at 1,074 kWh per year (based on 750 standardized hours), roughly $197 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 102% more than the median room air conditioner (rank 405 of 439) — so the state you live in matters more than usual. The same unit costs $141 a year in Nevada but $566 in Hawaii — electricity rates, not the appliance, make the difference. It also meets ENERGY STAR's stricter “Most Efficient” criteria.
