Neither type is automatically more efficient. A freezerless refrigerator can use less energy than a refrigerator-freezer in a particular model comparison, but the U.S. Department of Energy (DOE) treats them as separate product classes and does not establish a universal winner. Compare the current models’ annual energy use in kilowatt-hours (kWh), while accounting for capacity, features, and whether you will need a separate freezer.
What counts as a freezerless refrigerator?
In DOE’s residential appliance standards, the relevant category is called an “all-refrigerator”; “freezerless refrigerator” is common consumer wording for it. A refrigerator-freezer combines refrigerator and freezer compartments. DOE sets separate maximum-energy-use equations for all-refrigerators—including manual-defrost and automatic-defrost types—and for several refrigerator-freezer classes. Those equations define regulatory limits by class; they are not measurements of every product on sale and do not show that one category always uses less energy. DOE product-class standards

Models within either category can differ in size, design, and features. A freezerless model also does not provide the freezer capacity your household may need, so include any separate freezer in the comparison.

- Check annual energy use. Find the kWh/year figure on the current energy information for each model. Compare the actual models rather than assuming that a category label predicts consumption.
- Match capacity and installation format. Keep size and form reasonably similar. Comparing a much larger refrigerator with a smaller one will not tell you which design is more efficient for equivalent storage.
- Account for configuration and features. Freezer placement, automatic ice makers, and through-the-door dispensers can affect energy use. DOE’s kitchen-appliance guide gives historical general comparisons, not a substitute for current model specifications. DOE’s refrigerator and freezer guide
- Include the whole household setup. If a freezerless refrigerator means buying or keeping a separate freezer, factor in its energy use, purchase cost, and usable storage. Also consider your local electricity rate and the upfront price of each option.
- Consider lifetime cost, not just the efficiency label. DOE’s Federal Energy Management Program (FEMP) says an efficient product is cost-effective when lifetime energy savings, discounted to present value, exceed any additional upfront cost. DOE FEMP energy-efficient products guidance
What DOE’s example figures do—and do not—show
In 2023 guidance, DOE FEMP gave an example for an 18.1-cubic-foot, top-freezer, automatic-defrost refrigerator: its ENERGY STAR case was listed at 363.5 kWh/year, versus 404 kWh/year for the less-efficient case. The figures illustrate an efficiency comparison within that refrigerator type; they are not a test of an all-refrigerator against a refrigerator-freezer. The table’s price assumptions were in 2022 dollars. DOE FEMP residential refrigerator guidance

DOE’s buyer guide also reports that top-freezer models used 10%–25% less energy than bottom-freezer or side-by-side models, and that automatic ice makers and through-the-door dispensers increased energy use by 14%–20%. These are historical generalized comparisons. They concern configuration and features—not freezerless refrigerators versus refrigerator-freezers—so check current energy information for the exact models you are considering.

Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Which type makes more sense for your home?
- Choose based on measured use if your priority is energy consumption: compare annual kWh for similarly sized models with comparable features.
- Include separate-freezer demand if your household freezes food regularly. A freezerless refrigerator may require another appliance, changing the combined energy use and cost.
- Weigh space and usable storage if kitchen dimensions or the mix of fresh and frozen food matters more than the appliance category alone.
- Compare purchase price and electricity rates to estimate operating cost in your location. A lower-kWh model may not be the lower-lifetime-cost choice if its upfront premium outweighs the savings.
Without current, similarly sized model data for both categories, there is no evidence-based percentage advantage to assign to freezerless refrigerators as a group. The defensible answer is model-specific: compare current annual kWh and evaluate the complete storage setup your household will use.
