What sits beside it in the ranking
Hisense RQ17A4CSD ($86/yr, 459 kWh/yr) costs a little more to run than the Sub-Zero ID-30CI. Kenmore KKFDR32.3X20-SS ($86/yr, 458 kWh/yr) costs a little less.
Comparing Sub-Zero's own models
Sub-Zero makes 26 ENERGY STAR certified refrigerators; this one ranks 20 of 26 for running cost, between the brand's cheapest, the DEU2450R/ADA/* at $30/yr, and its priciest, the CL4850S/S/* at $140/yr.
What this adds up to over time
Over the 13-year service life NAHB reports for this category, running the Sub-Zero ID-30CI costs roughly $1,119 in electricity, separate from the purchase price.
Weighing a replacement
Running above the category average, $86/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.
Protecting what you have
Whether or not the Sub-Zero ID-30CI ever needs replacing, a repair is the more common failure for a refrigerator, one a protection plan budgets for ahead of time.
