Make a door to cover an area that has 4 a/c units?
I made a simple removable screen, but we only have one unit
This project might help you. I spoke with the installer who just put in a new unit for me. He told me that you need to allow at least 2 feet of clearance on all sides for the unit. I'm planning on doing something very similar to this since they had to put my unit in the front of the house. Wasn't that lovely?
