We kept our freezer in the garage in upstate NY for years. Then in the basement in NH, and now in the garage in NC. We never had an issue, except as some have said, some days, the interior of the freezer was probably warmer than the outside air. In NY, we were just outside Adirondack State Park, so we could count on a week of -20 degrees for the low (and +10 for the high--gosh, I miss that! Not!)
