Thanks for the comments so far.

I have joined the Garage Journal website and spent a couple of minutes perusing it. Looks like some good info but I'll probably have to read quite a few threads.

To clarify, the 911 will stay in the existing garage, I'm just thinking this might be an opportunity to add some much needed work space. I have an unfinished basement that I do use for woodworking stuff but it's not practical for car stuff.

What I'm considering is putting the compressor in the workshop area (or possibly covered outside) and then just piping the connection into the garage. I like the outside idea because I would have a perfect spot for it, it would reduce noise and it would not take up precious space inside the workshop area.

I would like to have enough room to be able to work on a motor on an engine stand comfortably. A wall-mounted A/C unit sounds like a good idea. The workshop area would be on the south side of the house so it would heat up very quickly in the hot Georgia summer months.

I'm thinking a small portable electric space heater would be enough to knock the chill down on the few days that it gets really cold. But I should probably plan on a dedicated circuit for the A/C and heater. 1 should be ok since neither will be running at the same time.

200 sq ft sounds like a lot but I suspect it fills up fast.
