Right next to it on the list
A rank or two either side of the Comfort Aire RADS-253R03: Friedrich KCVM24B30A ($252/yr, 1,338.5 kWh/yr), then Frigidaire FHWW245WE2 ($254/yr, 1,353.4 kWh/yr).
Within the Comfort Aire lineup
Of the 4 ENERGY STAR certified room air conditioners Comfort Aire makes, the RADS-253R03 costs the most to run, $179/year more than Comfort Aire's cheapest, the RXTS-81A.
What this adds up to over time
10 years is NAHB's typical service life for this category; at $254/year, the Comfort Aire RADS-253R03 adds up to about $2,544 in electricity over that span.
Shopping for a new one
The Comfort Aire RADS-253R03 runs above its category average. If the room air conditioner you actually own is older still, likely well past ENERGY STAR's efficiency baseline when it was made, a current certified model could cost meaningfully less than this model's $254/year every year.
Worth comparing a few current certified models before deciding.
If you're keeping it
Whether or not the Comfort Aire RADS-253R03 ever needs replacing, a repair is the more common failure for a room air conditioner, one a protection plan budgets for ahead of time.
