Did You Know?
1. The time it takes for a freezer to get cold can vary depending on several factors, but on average, it usually takes around 4 to 12 hours for a freezer to reach its optimal freezing temperature of 0°F (-18°C).
2. Freezers operate most efficiently when they are about 75% to 85% full. This is because the items stored inside act as thermal mass, helping the freezer maintain a more stable temperature and reducing the workload on the compressor.
3. Never put warm or hot food directly into the freezer. This can increase the internal temperature, making the freezer work harder to cool down and potentially affecting the quality of other frozen items. It’s best to allow hot food to cool down to room temperature before placing it in the freezer.
4. Placing a container of hot water or bags of ice into an empty freezer can help speed up the cooling process. The heat transfer between the hot water/ice and the freezer’s cold air helps to lower the internal temperature more rapidly.
5. If you want to freeze something quickly, spread it in a thin layer on a baking sheet before placing it in the freezer. This allows for faster heat transfer and ensures that the item freezes more evenly and rapidly compared to if it were in a thick, compacted form.
Average Freezer Cooling Times
When it comes to cooling down a freezer, the average time it takes to reach a temperature of 0°F (-18°C) is about four hours. However, it is important to note that this can vary significantly depending on various factors such as the model of the freezer, its size, and the starting temperature.
The actual freezing time can range from as little as two hours to as long as 24 hours. Stand-alone upright freezers generally take around four hours and twenty minutes to cool down, while chest freezers take slightly longer, averaging around four hours and fifty-five minutes. On the other hand, freezer-refrigerator combos can take up to twelve hours to reach the desired temperature. It is crucial to wait until the freezer reaches 0°F before adding any food to ensure proper preservation.
Cooling Times By Freezer Type
Different types of freezers can have varying cooling times. Specifically, upright freezers take an average of four hours to cool down. However, there can be slight differences depending on the brand. For example, Frigidaire and GE upright freezers generally take four hours to reach the desired temperature. Koolatron and Unique upright freezers, on the other hand, cool down a bit faster, taking around two to three hours. Maytag upright freezers, known for their spaciousness, may take slightly longer, ranging from six to eight hours.
In contrast, chest freezers take slightly longer to cool down compared to upright freezers. On average, they take around four hours to reach 0°F. Frigidaire and GE chest freezers both fall within this average cooling time. However, Magic Chef chest freezers cool down a bit faster, taking around two to three hours, while Hotpoint and Maytag chest freezers may take longer, ranging from six to eight hours.
Freezer-refrigerator combos, which provide the convenience of both a freezer and a refrigerator in one unit, have longer cooling times compared to stand-alone freezers. LG fridge-freezer combos take around two to three hours to reach the desired temperature, while Samsung models cool down in just two hours. On the other hand, Whirlpool and GE fridge-freezer combos can take up to a full day, or 24 hours, to cool down. Magic Chef fridge-freezer combos fall within the average cooling time of four hours.
Cooling Times For Specific Freezer Brands
Within each freezer type, different brands may have slightly different cooling times. For example, Frigidaire upright and chest freezers both take four hours to cool down. GE offers similar cooling times for both their upright and chest freezers, with both models reaching the desired temperature in four hours as well. Koolatron upright freezers cool down slightly faster, taking two to three hours. Unique upright freezers, known for their innovative features, fall within the average cooling time of four hours. Maytag upright and chest freezers may take a bit longer, with cooling times ranging from six to eight hours.
For fridge-freezer combos, cooling times can also vary. LG models take two to three hours to cool down, while Samsung models cool down in just two hours. On the other hand, Whirlpool and GE models have longer cooling times, with both fridge-freezer combos taking a full day, or 24 hours, to reach the desired temperature. Magic Chef fridge-freezer combos fall within the average cooling time of four hours.
Factors Affecting Freezer Cooling Time
While the average cooling times provide a general guideline, it is important to consider various factors that can affect the time it takes for a freezer to cool down.
Firstly, the starting temperature of the freezer plays a role. If the freezer is already cold or has been turned off for a short amount of time, it may cool down faster.
Installation in a warm room can also impact cooling time. If the room temperature is high, it may take longer for the freezer to cool down.
The age and condition of the freezer can also play a role. Generally, newer freezers with better insulation tend to cool down more efficiently.
Additionally, the frequency of opening the freezer door can affect the cooling time.

Frequently Asked Questions
How long does it take for a freezer to get cold after being plugged in?
The time it takes for a freezer to cool down after being plugged in can vary based on several factors. Generally, it can take approximately 12 to 24 hours for a new freezer to reach its optimal temperature. However, this timeframe can be influenced by variables such as room conditions, freezer size, and the initial temperature of the food being stored. These factors collectively impact the cooling process and determine how quickly the freezer can achieve its desired temperature.
Will an empty freezer get cold?
Yes, an empty freezer will still get cold, but it may not be as efficient as a full one. The lack of frozen food means that there is less mass to retain the cold, so the unit may have to work slightly harder to reach and maintain the desired temperature. However, it is important not to overcrowd the freezer, as proper air circulation is necessary for efficient cooling. So, while an empty freezer can still become cold, it is ideal to strike a balance between having enough contents to retain cold properly and allowing enough space for air circulation.
How long should a freezer run before putting food in?
To ensure optimal performance and food preservation, it is recommended to allow a freezer to run for at least two hours before placing any items inside. This period allows the freezer to reach its ideal temperature and stabilize its internal environment. Following the manufacturer’s instructions to set the temperature dial appropriately is essential for effective freezing and preservation of food. By allowing the freezer to run for the suggested duration, you can maximize its efficiency and ensure your food remains at the desired temperature for long-lasting freshness.
Do you have to leave a fridge for 24 hours?
It is recommended to allow your fridge or fridge freezer to settle for a minimum of 4 hours before plugging it in. During this time, the appliance can stabilize its internal temperature and get ready for food storage. Once the 4 hours have passed, you can set the thermostat control to on and start using the fridge. However, it’s important to remember to give the fridge enough time to cool down to safe temperatures before placing any food inside. This additional cooling time ensures that your groceries stay fresh and prevents the growth of bacteria.
