I have a house that has settled a bit and my a/c units outside are not
level. I would say they are at 5-10 degrees from level. My
brother-in-law tells me I shoulod fix this. Is there any truth to
this? If so why?

It is very important that any window unit NOT be level and here's why.
When it rains the unit can channel water towards the house if it is
leaning towards the wall. This can cause a lot of water damage. So,
it is better to have the a/c be slanted slightly away from the house to
avoid this situation. If you tried to get it dead level there would
still be a chance that it could be nudged slightly towards the house.

I learned this the hard way when my window unit channelled rain water
towards the house where it got into the wall cavity requiring me to
demolish and replace all of the wall board and insulation in the
damaged area. I now take great pains to make sure my a/c is leaning
slightly away from the house. This obviously does not apply to outdoor
compressors.
