K�hl+ KHVL28B35B
Under the DOE test basis of 750 hours a year, the K�hl+ KHVL28B35B draws 1,495 kWh — about $281 at the U.S. average rate, concentrated in the months you actually run it. It sits near the bottom of the certified table — using 181% more than the median room air conditioner (rank 391 of 396) — so the state you live in matters more than usual. The same unit costs $185 a year in North Dakota but $697 in Hawaii — electricity rates, not the appliance, make the difference. It also meets ENERGY STAR's stricter “Most Efficient” criteria.
