Hi ,
I have central air in my house and I live in the northeast.
There is an outside unit that sits on a slab that I think brings in
the air. Its a box and every side is metal screen.
I was driving around my neighborhood yesterday and I saw that some
people in my neighborhood had their AC units covered, just the top,
with plastic. This would cut down on the air intake but maybe it is
more important that ice and snow do not get inside? Are you supposed
to cover the top of the intake in the winter? Thanks

No. Just like you're not supposed to cover the roof turbines or block ridge
vents.
