Well.....LOML gave the approval today to go and pick up some A/C for the shop. I decided on a 10,000 BTU unit and a 8,000 BTU unit for a total of 18,000 BTU of cooling. YEA!!!!!!
Now....how does one that knows nothing about installing a window A/C unit in a metal building that does NOT have any windows.....
1. How much oversized is the exterior hole cut in the wall section?
2. How does the unit get its support when all there is, is the metal skin on the building?
3. Should the metal hole be lined with wood or something to form a frame for the window A/C unit?
If this was conventional construction, I would already have them installed and running...but this is a METAL building and I already have a leaky roof and I don't need a couple of holes in the wall that I can't do anything with.
Any and all help would be greatly appreciated.
