Right next to it on the list
A rank or two either side of the Friedrich KHVS12B33A: Friedrich KCVM14B10B ($123/yr, 652.8 kWh/yr), then GE PWJV14W**# ($123/yr, 656.3 kWh/yr).
Within the Friedrich lineup
Ranked 13 of Friedrich's 28 certified room air conditioners, this sits between the CCV08A10A ($75/yr, the brand's cheapest) and the KCVL36B30A ($394/yr, its priciest).
Cost over its typical lifespan
10 years is NAHB's typical service life for this category; at $123/year, the Friedrich KHVS12B33A adds up to about $1,234 in electricity over that span.
Shopping for a new one
The Friedrich KHVS12B33A 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 $123/year every year.

If you're keeping it
At $123/year just to run, a room air conditioner is worth protecting against an unplanned repair bill on top of that.
