I aquired an older standup 16 qf freezer. I have the temp steady at

as good as zero?

I've been told for years to keep such things full. Even if you put
water filled
milk jugs in it the mass will keep the freezer from running as much.
Yes, if there's a lot of air in the freezer, when you open the door, a
lot of cold air will fall out at the bottom, replaced by room air at the
top. BTW, I have a 45 year old working freezer and was wondering if
replacing it with a new higher efficiency unit would be worth it. So I
picked a warm summer week and put the Kill-a-Watt unit on it. Turns
out, it would take many years to pay for a new freezer with the savings
on electricity.
