When I first built my shop, one of the things that I had to include was air conditioning. I had a big window mount unit that I had planned to repurpose to that end and had had the electrician rough in the circuit for future completion. Recently came to learn that the wiring that was used was too light for the unit. Apparently it needs wiring that can support a 30 Amp circuit and what I have is only for 20 amp. So now the wiring has to pulled and replaced.
Beyond that, the A/C is going to need a hole in the wall in which to reside and since I used 2 x 6 studs in my framing, I now plan to use 2 x 12's to create the box into which the unit will be stuffed. For this to work I have to create the equivalent of a new window opening, meaning jack studs and headers and all that good stuff. The plan is to sister the wall studs as far up as the fire break boards, and then lay the bottom of the box on the fire break. Inside will be flush with the existing wall, so I will have 6 inches of box floor protruding beyond the exterior wall to offer better support for the A/C unit itself as it is fairly heavy. The whole box is 12 inches deep; the header over it will be built from 2 x 6's laid on edge. For that I will need four layers each to be cut to fit. Oh what fun. I did remove and set aside the lower section of wall board and i am prepping that in advance for the re-assembly portion of the program.
As for the wiring, that is likely to require the services of an electrician. Hopefully it can be done as a side job by someone who happens to know what they are doing around breaker boxes; And that ain't me.
