Most freezers (except for those with a garage-ready design) aren’t built to function in extreme weather conditions like an unheated garage. If you live in an area with huge temperature swings, you should avoid storing a standard freezer in the garage in order to prevent it from overheating, shutting down, or costing you more money to run it. But if your garage is insulated and climate controlled, you can keep any type of freezer there. Make sure it’s in a dry space and out of direct sunlight so it doesn’t struggle to maintain the correct interior temperature.
