Several people have told me that a freezer works much harder if it is in a very cold environment. That makes no sense to me. I am wondering if that is correct.

This is a question that has an "in principle" answer and an "in practice" answer. The "in principle" answer is that a freezer should work better the colder the surroundings. In fact if the temperature is cold enough continuously, you do not need a freezer at all. The "in practice" answer is that a freezer has a compressor and an electric motor driving that compressor. The seals, valves, and assorted mechanical moving parts may get sluggish if the temperature is too cold so that the freezer may have to work harder in a low temperature environment.
