Lifespan
NAHB's Study of Life Expectancy of Home Components does not publish a figure for freezers, so no lifetime cost is shown here rather than a guessed one. The annual and monthly figures above stand on their own.
Is it worth replacing?
At $93/year, this is on the expensive side for a freezer; the cheapest certified model in this category runs about $26/year, worth knowing before buying either the ARTT ATUF21ES or its replacement.
Worth comparing a few current certified models before deciding.
If you're keeping it
$93/year to run is the predictable cost of the ARTT ATUF21ES; a protection plan covers the unpredictable one, a repair bill.
Where this number comes from
Two sourced numbers, nothing modeled: ENERGY STAR's certified kWh/yr for this exact model, and EIA's published state electricity rate. The full Freezer category page shows all 658 freezers ranked by cost; the state-rate guide covers the half of this number that isn't the appliance.
