Model
Summit ADFD2D24
Rank #188 means 187 of the 622 freezer models we track cost less to run each year; the 5th efficiency percentile means it uses less energy for its size than 5% of those models.
What does the Summit ADFD2D24 cost to run per year?
Among the 622 freezer models we track, the Summit ADFD2D24 sits in the below-average-cost group, rank #188, at roughly $66 a year. It uses 14% less energy than the U.S. federal standard model in its class, which would cost about $77/yr to run, a saving of roughly $11 a year. Efficiency-wise, once size is accounted for, it lags most of the class, ahead of only 5% of the models we track. This class has no published efficiency-factor figure beyond annual kWh itself, so at 3.5 cu ft (the class spans 1.1 to 23), size is the clearest lever we can point to for this model's running cost.
Immediately around it on the leaderboard, the Insignia NS-UZ11**27-C at $66/yr runs a little cheaper and the Vissani MDUF11**5 at $66/yr runs a little more, a sense of how tightly models are packed at this point in the ranking. A freezer typically stays in service for somewhere around 14 years; over that span, the Summit ADFD2D24's $66/yr adds up to roughly $924 in electricity alone, before purchase price or repairs.
By the numbers
The Summit ADFD2D24 normalized against its whole class, so each figure means something.
What it costs you over time
Running cost is an every-year number, so it compounds. At $66/yr, here is what the Summit ADFD2D24 adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Summit ADFD2D24 costs about $660. That is roughly $110 less than a standard model in its class, which would run closer to $770 over the same ten years.
How the Summit ADFD2D24 compares
The freezer class we track runs from $25 to $120 a year. At $66/yr, it runs about $9 a year cheaper than the class median of $75, and it is about $41 a year more than the cheapest freezer to run at $25. Against the US federal standard model for its class at about $77/yr, the Summit ADFD2D24 uses 14% less energy.
What drives its running cost
At 3.5 cu ft, the Summit ADFD2D24 is a small freezer for its class, which spans 1.1 to 23 cu ft with a median of 13.8 cu ft, at the small end of the class, capacity itself is doing a lot of the work to keep that figure down, separate from how efficient the unit actually is.
- Interior volume. As with refrigerators, more cubic feet of frozen storage generally means a bigger compressor and a higher annual energy figure.
- Insulation and defrost type. Better-insulated cabinets lose less cold to the surrounding room, and frost-free (automatic-defrost) freezers run a periodic heating element that a manual-defrost model does not.
- Chest vs upright design. Door orientation affects how much cold air escapes per opening: top-opening chest designs generally hold cold better than front-opening upright ones.
Common questions
Is the Summit ADFD2D24 cheap to run?
Yes. Its $66/yr running cost puts it at rank #188 of 622, below what most freezer models we track cost to run.
How much does the Summit ADFD2D24 cost per month?
About $5.49 a month, which is the $66 annual estimate spread across twelve months at the US average rate of $0.1856/kWh. Your own bill scales with your local electricity rate and how heavily you use it.
How is this running-cost figure calculated?
The formula is annual kWh times price per kWh: 355 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $66 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Summit ADFD2D24 for its size?
5th percentile once size is factored in, a fairly typical result for the class.
