It is acceptable to keep some freezers in an unheated garage. However, a number of factors need to be taken into consideration when it comes to placing a freezer into an unheated space.
Freezers are designed with different operational specifications. Whether your freezer performs well in an unheated garage depends on both the type of freezer and the climate where you live. Most freezers are designed to operate appropriately in temperatures between 32 and 110 degrees Fahrenheit. Some freezers are designed to withstand and operate effectively in a broader temperature range. Unheated garages sometimes experience temperatures outside of these zones, depending on geographic location. If your garage is likely to experience lower temperatures, a space heater is a possible solution.
