Right next to it on the list
A rank or two either side of the Hisense AW1823TW3W: Frigidaire FHWW185WE2 ($169/yr, 900 kWh/yr), then Keplerx KBRC18RSVE2 ($169/yr, 900 kWh/yr).
Same brand, different models
Ranked 15 of Hisense's 16 certified room air conditioners, this sits between the WCT06W25A ($62/yr, the brand's cheapest) and the AW2223TW3W ($207/yr, its priciest).
Cost over its typical lifespan
NAHB's Study of Life Expectancy of Home Components puts a typical room air conditioner's service life at 10 years; run the Hisense AW1823TW3W that long and it costs about $1,692 in electricity, on top of whatever it cost to buy.
Shopping for a new one
Running above the category average, $169/year is exactly the kind of number that makes a newer, more efficient model pay for itself faster.
Worth comparing a few current certified models before deciding.
If you're keeping it
$169/year to run is the predictable cost of the Hisense AW1823TW3W; a protection plan covers the unpredictable one, a repair bill.
