Framers have nearly finished a garage addition for me that I will use as a workshop. It’s about 12x25, with a garage door. Framers will leave it finished on the outside, open studs on the inside. Items I need to do are have electrical run to the room, install window unit AC, install garage door motor, put up plywood walls, insulate, run outlets (ok with appearance of surface mount but unsure of benefits). What is the order in which I should tackle these things? Certainly, I don’t want to do too much before I get it cooled, unless I wait for cooler weather.

It really could be done in any order depending on 2 decisions really.
-Do you want surface receptacles or not
-Do you want/need a small sub panel in the shop or not.

If you want AC prior to anything, start with it and install. For now, you can at least use a heavy gauge extension card to run the AC unit while you are working.

The benefit of surface mount is if you don't get the layout perfect the first time due to future new tools, more efficient work flow, etc, it's not a big deal to change.

I have a similar scenario, 10 x 20, storage shed attached to house, I’ll convert to a hobby woodwork shop. I’ll remove existing drywall, insulate, retain existing 115V electrical outlets in wall, and re-wall with T1-11, plywood or OSB. I plan to have a electrician install a sub-panel to provide 115/230 - the main electrical panel, and electric meter, for the house is attached to the exterior of the storage shed wall but I’m not messing with the main. Once the subpanel is installed, I’ll install exterior outlets myself for maximum flexibility (location in room and height on wall) in placing outlets for woodworking power tools. So you might want to decide on how you want to do the electrical, interior of walls or exterior of walls, before preceding to the next steps.

If you could put in your window AC and run it from an appropriately sized extension cord now I could see some advantages of drying out and stabilizing moisture content of wood framing etc in the shop before you proceed with the other steps - though that might not be to important.

Downsides? How painful is it to have them on the outside of the wall? Is it just that they get in the way? I am leaning in that direction.

I plan to use a lot of French clear hangers on the walls to give flexibility. I also envision shifting my layout of tools, workbenches over the years a good bit.

So much going on, I hadn’t even thought of running the ac with an ext cord. I got work to do tonight.

As long as you move put up plywood walls to the end, and insulation to the step right before that, you're golden.

I've got flush & surface boxes in my shop. I haven't caught my elbows on anything yet, so there's that

Conduit make pretty sturdy jig hangers too!

Sorry. In my line of work, we use “painful” instead of “inconvenient.”

If you install enough sockets, you won't have to move them later on.

That's true, but you need to have separate circuits if running a table saw & a dust collection system at the same time. Running multiple dedicated power leads back thru a single run of 3/4 or 1" conduit to you panel will help separate loads where needed.

Then again, OP hasn't mentioned what he plans to do with the new space or if he needs 220V for the AC or any other tools.

I don’t really have any plans for 220v. Maybe short-sighted but I haven’t considered needing anything other than 110 for my window unit. This is climate controlled reloading space, first. I do think a couple of dedicated circuits for multiple power tools would be wise.

If that is the planned usage, disregard anything I said before

Will the AC unit provide cooling & heating? May want 220V for that to save on your electric bill.

A watt is a watt is a watt. Some larger stuff runs slightly more efficiently on 220, but we're talking 3% or under type numbers.

I somewhat agree with you, but 3% is 3%. Dealing with lights dimming every time the compressor kicks on and the fact he has the opportunity to run 220V from the get go, why wouldn't you put in a 220V circuit?

Not arguing with you and I haven't had a wall AC since way before LED bulbs came out. Do new window units have built in soft starts? My 120V Bosch table saw has soft start and eliminated mst of the dimming in my little shop (all 120V) which is 10 x 23. My space was already sheet rock finished with flush devices from the previous owner. I had to add dedicated surface mount circuits opposed to tearing out drywall.

I have a 20x20 uninsulated garage that I reload in. I was having a problem with my press and dies starting to rust a bit from the heat and humidity. I put a LG window unit in there that’s 8000btu. I was limited due to window opening. Anyway, I run it 24/7 at 75degrees and set it to dry mode or power saver. Haven’t really seen a significant bump in electric bill but my reloading stuff isn’t rusting anymore and it’s comfortable enough for me to work in there during the heat of the day.
