I'd like actt in my shop, because I am a fat Yankee in the south.
Window unis are $50 used around here. But I don't have a window. Why is it a bad idea to sit one on sawhorses and keep the doors shut this summer?

Well, you need a place for it to blow the hot air that it's turning into cold air. It's really just a heat exchanger.
Dryer vent? It runs through the ceiling. ...

Still wouldn't be doing much. Notice that pretty much every window unit hangs completely outside. They create more heat than cold.

Because they generate more hot air out the back than cold air out the front.
A window unit is a heat mover, not a cold generator. If you move the heat from the room back into the room, plus add the electrical energy used to run the unit, that is converted to heat, you end up with a heater, not an air conditioner.
Cut a hole in the wall and install the unit.
Edit: even better yet, install a heat pump and have heat in the winter.
A Portable AC unit would be a better option
You need to cut a hole in the wall, or pay a lot more for a portable unit and cut a smaller hole in the wall. The fan in a window unit isn't designed to push air through a duct.
Back in the days of old, when dinosaurs roamed the earth and heat pumps didn't exist, it was commonplace to mount a large window unit through a hole in the wall of a house as a permanent installation.
In reply to 1988RedT2:
It wasn't that long ago. My last house had no central HVAC and was air conditioned with window units into the late 90s. Heat was a wood burning stove with a pot burner oil furnace as back up. We ran it that way for almost 20 years.
A portable unit is a possibility. I have a 10K btu portable that does a pretty good job. They are much easier to plumb. You probably don't want to dump that heat and humidity into the attic. That's asking for a mold and mildew problem. Dump it through the wall and outside.
The textile mill I worked in let guys set window AC units on crates and point the cool air at themseklves on the inspect stations in the un air-conditioned mill. The area behind the units was miserably hot, like 120f in the summer.
My shop has two window AC units. One in a window, and one in a framed hole in the wall. They work great.
