My landlady/roommate has a large refrigerator/freezer where, IMO, the
door should ope on the other side.

It's an Amana, maybe 10 years old, or 20?, with a tall, hinged door on
the bottom for the freezer, and a fridge above it.

It's clearly designed to open from either side.

How much time would this take me? I think it takes 2 people to hold
the door in place while attaching the top bracket/hinge, right? For
the fridge. Maybe I can prop the freezer door on a book while I
attach its hinge.

How much extra time will it take since the screws have been sitting
this way for 10 or 20 years?

She hasn't even said anything. It just bothers me because it's
wrong, but it doesn't bother me enough to spend more than 2.5 hours,
and I don't want to tell her I'm going to fix it and then not, and
then it will bother her that it's not fixed when now she doesn't even
know it's broken.

My wife can do it by herself. As Ed says 15 minutes. Take off top
hinge, Lift off door. Swap handle over. Swap over bottom hinge. Set
the door on it and put in the top hinge. The magnetic seal will
usually hold the door until you get the top hinge lined up.
