I haven't.
But I am under the impression that the need to be licensed in order to get the refrigerant (?), I believe is what steers most DIYers away from this task?

I could probably do it, but why would I want to?
A pro can start and finish today. Two weeks from now I would still be troubleshooting. How long can you go without heat/air?
Pay the pro.

through the wall in a sleeve (42 inches wide, 16 inches high, 20 inches deep), 14,000 BTU 230 volts. There is need to add refrigerant to these is there? The problems look like cutting the hole in the wall and hooking up the electricity. Any experience with these (apparently popular for motel rooms, that kind of thing)?

They are very similar to a standard window unit. Cut a hole in the wall, frame/finish the hole, slap in the wall sleeve, shove in the unit and plug it in. You may need an electrician to install a circuit for it. Greg

Through-the-wall??
You do not need a license to install that....to a point:
You need to make sure you aren't cutting through any electric or plumming that may be behind the wall (where you are cutting the hole). You have to make sure you "shore up" the studs (in the wall) that you are cutting to make the hole. THEN you need to run electric to the unit, which you DO need to have someone with a license to do.
Not making it up, but I just installed one yesterday at a friends house. I framed out the hole that I cut and put 'J' channel around it (on the outide to make the vinyl siding look better) and framed the unit (on the inside to make IT look better). It is all ready to go except for the electricity. I could have run the electric. It's not that hard to run the proper wire and install a breaker, but I am not a licensed electrician so my friend will be calling in someone that is licensed to finish it off.
Is it hard? No. But you do have to take precautions so you don't end up causing more work for someone else to fix.....

yourself with the excption of the copper line set and the refer charging. Anyone with basic skills and common sence should be able to get it done. There are alot of variables installing all the ductwork for a central system. You will need to be EPA cert. to buy the equipment It comes precharged with freon. It is a big job. If you can getaway with a wall unit,That might be the simplest amd easyest way for you to go. any questions feel free to email me. Steve

The professional A/C installer said it best. Mount and wire everything, then have a pro do the copper lines and freon stuff and startup.

I've been installing central AC for a friend of mine, for about the last five years. As a part time job. There is a lot more to the job than you'd think.
As others have mentioned, need a license to insert or remove refrigerant. I've invested a pile of money into equipment, which you'd also have to purchase.
