The best energy efficient chest freezer combines three things: an efficient design (chest rather than upright), manual defrost, and the right size for what you store. ENERGY STAR says certified freezers are at least 10 percent more efficient than the federal minimum, and that a certified chest freezer uses about 215 kWh a year, roughly $30 of electricity.
We compared chest freezers on Amazon that list ENERGY STAR status, a daily energy figure or a low-impact R600a refrigerant.

How We Chose the Best Energy Efficient Chest Freezer
To choose the best energy efficient chest freezer, we compared chest freezers sold on Amazon in the U.S. on listed capacity, outside dimensions, the coldest listed temperature, defrost type, any listed daily or yearly energy use, garage-ready ambient ratings, locks, baskets and warranty length. We then read owner reviews for recurring problems such as lids that do not seal, frost build-up, noisy compressors and units that arrive dented, and we left out listings whose specifications contradicted themselves.
We checked efficiency claims against ENERGY STAR’s freezer guidance (certified freezers are at least 10 percent more efficient than the federal minimum, chest freezers are usually more efficient than uprights, and manual-defrost models use about half the energy of automatic-defrost ones) and food-safety points against FoodSafety.gov’s cold storage chart, which says food kept continuously at 0°F or below stays safe indefinitely. Our full process is explained on our How We Test page. We do not list prices or star ratings because they change daily.
