Midea MAW12AV1UWT-C
The Midea MAW12AV1UWT-C is certified at 600 kWh per year (based on 750 standardized hours), roughly $113 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 13% above the median room air conditioner, ranked 255 of 396. The same unit costs $74 a year in North Dakota but $280 in Hawaii — electricity rates, not the appliance, make the difference.
