I have an air conditioner installed through the wall in my house. I plan to remove it and need to close the hole. I'd like to do it myself rather than pay someone but have no idea how to go about it. The house has aluminum siding outside, and I have some spare pieces. The inside will eventually be finished with drywall. The sides of the opening are framed. Do I need to add a vertical piece of 2X4 at the center of the hole to support the drywall? Do I just cut a piece of plywood and nail it on the outside? If so do I put anything over the plywood or just put the siding on top of it? In other words, I don't have a clue and could use some expert advice. Thanks.
