Midea makes 41 ENERGY STAR certified freezers; this one ranks 35 of 41 for running cost, between the brand's cheapest, the MRC04M3C** at $33/yr, and its priciest, the MRU21C7B** at $94/yr.
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?
The Midea MRU21B4*** runs above its category average. If the freezer 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 $93/year every year.
Compare current ENERGY STAR certified freezers before buying.
Protecting what you have
The Midea MRU21B4*** already costs $93/year to run; a repair bill on top of that is the kind of expense a protection plan exists to smooth out.
The data behind this page
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.
