I am getting a new A/C unit installed on Monday and when I asked them to put rock under the pad to level it out they said they would put what ever I supply.
They reason I asked was my previous experience was the installers just kinda level with what ever they have which is some kind of mixture of soil and mulch and will eventually settle.
The two units sit on a side hill that is subject to erosion.
I know I should use a rock that has rough edges and corners so it is less likely to move.
The question I have: should I use a smaller stone or a bigger stone or something else?
I picked those two because they were the cheapest at the local BB store and bagged so I can get them home.
In the end it probably wont matter much but I figured I would ask as I have a couple days to figure it out.
