Midea MAT14R2FWTK

Under the DOE test basis of 750 hours a year, the Midea MAT14R2FWTK draws 755 kWh — about $142 at the U.S. average rate, concentrated in the months you actually run it. It sits near the bottom of the certified table — using 42% more than the median room air conditioner (rank 332 of 396) — so the state you live in matters more than usual. The same unit costs $93 a year in North Dakota but $352 in Hawaii — electricity rates, not the appliance, make the difference. It also meets ENERGY STAR's stricter “Most Efficient” criteria.
