March 9, 2020: CR's Coronavirus Resource Hub will keep you up to date on the virus and offers advice on how to keep yourself and your family safe.
Maybe you’re one of those people who likes to be prepared—making an extra pan of lasagna for last-minute dinner guests, stocking up on budget-friendly bulk foods, or prepping all of next week’s meals. If so, the freezer in your fridge can get pretty jam-packed. One savvy food-storage solution? Adding a stand-alone freezer.
Before you shop, you’ll want to decide whether a chest freezer or an upright model would best meet your needs—and available floor space. Next, consider size, capacity, and energy use.
To test freezers, our engineers fill each model with boxes of frozen spinach and run them in our test chambers for approximately six weeks to evaluate how well they keep the packages frozen.
The results allow us to judge their thermostat control and temperature uniformity (the ability to maintain the same temperature throughout the freezer cavity). Our engineers also measure usable storage capacity, which doesn’t always match what manufacturers claim.
In addition, we calculate energy efficiency, evaluate noise output, and judge how long a freezer can keep food frozen during a power outage. All this data is folded into an Overall Score for each model and appears in our freezer ratings charts.
When it comes to the two most popular categories of freezers—upright and chest models—we find that there's no clear winner. Below, we consider the pros and cons of each type. Other options include freezer drawers and portable freezers; for more, see below.
Pros: Chest freezers are wide open, except for their removable hanging baskets or, sometimes, dividers, so they offer more usable space than uprights. These models also tend to be slightly more energy efficient and are less likely to cause freezer burn on food. Because they don’t self-defrost like uprights, the temperature stays consistently lower. They're also the better choice if the area where you live is prone to brownouts or power failures—they tend to keep food frozen longer when the power is off. We find that they tend to be quieter than self-defrosting uprights.
Cons: Despite their hanging baskets, they can be harder to organize than upright models, and retrieving items buried near the bottom of the chest can be a reach. Their footprint is also larger than equivalent upright models—a 22 cubic foot chest freezer takes up a 2-by-6 foot footprint versus the 2 ½ by 2 ½ footprint of a same-size upright. Manual defrost (which can be time-consuming) is the only option.
Prices: Range from about $200 to $1,500.
Pros: Uprights take up less floor space than chest freezers—2 ½ feet square for 22 cubic feet of storage, compared to a chest's typical 2-by-6 footprint. They're also easier to organize. As with a fridge, shelves and bins inside and on the door make it easy to find things. You have the option of manual or self defrost. Note that manual defrost takes hours and you have to empty the freezer. But self-defrost freezers allow temperatures to rise temporarily, which might compromise performance. And, unlike chest freezers, uprights are available in a variety of finishes, such as slate and stainless steel.
Cons: In our tests, manual-defrost uprights had a hard time keeping their door shelves as cool as the rest of the interior. The shelves in these models also can’t be adjusted to improve storage. Self-defrost uprights tend to be noisy and may cost more to run. They also allow more air to circulate around food, making food more likely to get freezer burn. In our power failure simulation, all uprights allowed a relatively large temperature uptick after only 9 hours. And in all uprights, shelves and bins take up more space (up to 20 percent) than in chest types.
Prices: Usually higher than chest models, from $300 to $2,000.
Stand-alone freezers used to be all about utility, with no-frills designs and an open-box interior that made it a challenge to keep foods organized. Those bare-bones freezers are still available—and many of them do well in our freezer ratings—but we're also seeing a lot of improvements to the look and functionality of freezers. Consider these factors before you hit the store:
Location, Location
If you plan to keep the freezer in a living area, consider how noisy it is (and also how it looks). Most manufacturers say that their freezers can operate in a room where the temperature can reach up 110 degrees Fahrenheit, but check product specifications if you plan to put the freezer in an unheated area, such as a garage.
Sizing Things Up
Freezers, whether chest or upright, come in three basic sizes: compact or small (5 to 9 cubic feet), medium (12 to 18 cubic feet), and large (more than 18 cubic feet). Upright freezers have a smaller footprint for the equivalent storage space.
Blackout Recovery
Most manufacturers say that their freezers can keep food adequately frozen for 24 hours with the power off, as long as the freezer remains unopened. But our tests simulating a prolonged power failure showed that some uprights allowed a relatively large increase in temperature after only nine hours.
Consistency
Most of the freezers in our tests maintained a consistent temperature. Manual-defrost uprights were the exception. Without fans to circulate cold air, temperatures of on-door shelves were between 9 and 19 degrees higher than in the rest of the freezer.
Energy Use
Don't expect your new freezer to be quite as energy efficient as its yellow EnergyGuide label implies. That's because our tests are tougher and, we believe, more like real-world conditions than those specified by the U.S. Department of Energy. Energy Star products must meet certain governmental energy-efficiency standards.
Once you've gotten your freezer, you may want to give it a little help keeping its cool—and making food last longer. Check out these simple tips from our experts:
Save Energy
Keep your freezer in a cool spot, such as the basement, where it tends to stay well below normal room temperatures. Even though most manufacturers say models will operate in temperatures up to 110 degrees Fahrenheit, check the product info for specifications.
Minimize Frost
Open the lid or door less often. Keep an inventory of what’s inside so you don’t have to hunt around. Label food well for the same reason.
Store Food Correctly
Repackaging food in several layers of plastic wrap helps reduce moisture loss and freezer burn. Some common freezing rules of thumb: You can freeze ground beef for up to 4 months, and a whole chicken for as much as a year. A pack of hot dogs should only stay frozen for 1 to 2 months.
It’s an appliance with a pretty straightforward purpose, but some freezer options can make them more convenient to use (although they may bump up the price).
Some self-defrosting upright freezers we tested beep if their interior gets too warm.
In chest freezers, upright plastic dividers and sliding bins on racks help organize stored food.
We found some freezers equipped with this feature (useful if there are kids in the house), which blocks access or keeps the door from being left open.
Manual-defrost freezers (the only option for chest models) are generally more energy efficient, and less likely to cause freezer burn than self-defrosting models (uprights can be manual- or self-defrosting). It's wise not to let ice build up on freezer walls, which can decrease efficiency and increase your energy bill. It's worth noting that defrosting can take hours. On the con side, manual-defrost uprights had trouble keeping their door shelves as cool as the rest of the interior, with temperatures ranging from 9 to 19 degrees. Self-defrosting uprights did a better job of keeping their door shelves as cool as the rest of the freezer, and they save you the hassle of actively defrosting.
Without opening the door and letting cold air escape, you can see at a glance whether the freezer is on. Most models have this feature, and we think it should be universal.
Some uprights can cool large quantities of food more quickly. Other freezers have a soft-freeze option—handy if you can’t bear to wait for rock-hard ice cream to melt.
Pull-out freezer drawers are popping up in high-end kitchens, usually to supplement the freezer in a standard fridge. They can match the cabinetry or have a stainless pro-chef look. They are pricey, running $2,000 to $6,000 , and are typically available in 24-inch and 30-inch widths.
Portable freezers for boating or camping require a standard 110-volt household outlet or a 12-volt power source (like a car battery). Some hold up to 85 quarts and are equipped with wire baskets to organize food. They can be adjusted to refrigerate as well. There isn’t a wide range of brands making these, and we’ve found the smaller ones to be less efficient.
