Protecting Appliances in Garage During Freeze

So in BR, I have an attached garage, Heated room above and adjacent, where I am storing new appliances during a kitchen renovation. These are packed and never used oven/range, fridge, dishwasher. The garage itself isn’t climate controlled but due to the attached rooms being heated there is some temperature control. These should be fine, right? I tend to think they are, but considering the potential cost I’m a little worried. But on the other hand, moving it all into the house by myself will be a pain in the arse.
