Zephyr PRRFD24C2AS

Running around the clock, the Zephyr PRRFD24C2AS uses a certified 330 kWh per year — about $62 at the U.S. average rate, or $5.18 a month, the equivalent of a steady 38-watt draw. It sits near the bottom of the certified table — using 35% more than the median compact freezer (rank 107 of 128) — so the state you live in matters more than usual. The same unit costs $41 a year in North Dakota but $154 in Hawaii — electricity rates, not the appliance, make the difference. It also meets ENERGY STAR's stricter “Most Efficient” criteria.
