Seasons ST10VB2

The Seasons ST10VB2 is certified at 532 kWh per year (based on 750 standardized hours), roughly $98 at the national average — though seasonal use means your real bill lands in a few months, not twelve. That's close to the middle of the certified pack — about 0% above the median room air conditioner, ranked 222 of 439. The same unit costs $70 a year in Nevada but $280 in Hawaii — electricity rates, not the appliance, make the difference. It also meets ENERGY STAR's stricter “Most Efficient” criteria.
