Model
Zephyr PRRFD24C2AS-OD
Rank #149 means 148 of the 622 freezer models we track cost less to run each year; the 6th efficiency percentile means it uses less energy for its size than 6% of those models.
What does the Zephyr PRRFD24C2AS-OD cost to run per year?
At $61 a year to run, the Zephyr PRRFD24C2AS-OD runs cheaper than most models in its class, ranking #149 of 622 freezer models we track. It uses 22% less energy than the U.S. federal standard model in its class, which would cost about $78/yr to run, a saving of roughly $17 a year. Its 6th size-adjusted efficiency percentile is well below the class median, worth weighing against the raw cost figure above. At 3.9 cu ft, it is a small freezer for the class, which runs 1.1 to 23 cu ft; size and efficiency are the two levers behind the figure above, and this dataset does not carry a separate efficiency-factor column for this class.
Immediately around it on the leaderboard, the Zephyr PRRFD24C2AS at $61/yr runs a little cheaper and the Ellipse EFVC10S at $62/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 Zephyr PRRFD24C2AS-OD's $61/yr adds up to roughly $854 in electricity alone, before purchase price or repairs.

By the numbers
The Zephyr PRRFD24C2AS-OD 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 $61/yr, here is what the Zephyr PRRFD24C2AS-OD adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Zephyr PRRFD24C2AS-OD costs about $610. That is roughly $170 less than a standard model in its class, which would run closer to $780 over the same ten years.
How the Zephyr PRRFD24C2AS-OD compares
The freezer class we track runs from $25 to $120 a year. At $61/yr, it runs about $14 a year cheaper than the class median of $75, and it is about $36 a year more than the cheapest freezer to run at $25. Against the US federal standard model for its class at about $78/yr, the Zephyr PRRFD24C2AS-OD uses 22% less energy.
What drives its running cost
At 3.9 cu ft, the Zephyr PRRFD24C2AS-OD 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. Cubic feet of frozen storage is the first lever behind a freezer's running cost, ahead of insulation or defrost type.
- Insulation and defrost type. Two freezers of the same size can differ meaningfully on running cost based on insulation quality and whether they run an automatic-defrost heater.
- Chest vs upright design. Chest freezers open from the top, so cold air, which sinks, stays inside when the lid opens; upright freezers lose more cold air per door opening for a similar capacity.
Common questions
Is the Zephyr PRRFD24C2AS-OD cheap to run?
Yes, relatively. At $61 a year it ranks #149 of 622 freezer models we track, in the cheaper part of its class to run.
How much does the Zephyr PRRFD24C2AS-OD cost per month?
Roughly $5.1/mo, spreading the $61/yr estimate evenly across twelve months at $0.1856/kWh. Actual monthly bills swing with your rate and usage pattern.
How is this running-cost figure calculated?
We take the model's published annual energy use of 330 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $61 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Zephyr PRRFD24C2AS-OD for its size?
6th percentile once size is factored in, a fairly typical result for the class.
