I guess that all depends on where you are... it's already steadily below 70 here during the day, and it's only gonna get colder in the next month or so. There's a portion of the winter where it's pretty steadily under 30 degrees for a couple weeks or longer, too.

During that portion of the winter, the freezers won't even run, and for the months surrounding them, it'll more than likely only run once or twice a day.

For that entire period, there's almost nothing I could do that's more efficient than having them outside, because even letting the 'waste heat' from the pump and cooling coils heat the house, the house being warmer than the intended temperature of the freezer means it has to run more often to keep it's contents cold, and reduces the coils' cooling efficiency, making the pump run longer per cycle as well.

Even super insulating the freezer would still allow this to happen, although it may run less time per cycle and less cycles, it won't be as 'good' as it not cycling at all or cycling once-twice per day.
