I don't know why not.

As I recall there was a very complete thread on how to make a vacuum pump from an old refrigerator pump. Not sure about A/C but I would imagine it's the same thing. Do a search on the refrigerator vacuum pump and I'll bet you'll find something you can use. I have not yet ventured into vacuum bagging but it is something I'd really like to try. Anything for a better/no void layup is great news to me.

Yes, I know people who have a set up with a A/C vacuum pump.

You can get the parts from [link=http://www.veneersupplies.com/]Veneering Supplies[/link].
I built their vacuum pump with the Gast motor because I needed close to 29" Hg but a A/C should pull at least 14" for fiberglass parts but you really should use a cut-off switch from Veneering Supplies so it will cut off at the right time, especially if you're doing wings which only need around 7" Hg.

Look at this...we have just finished making ours . Will be used for vacuum bagging and vacuum forming. We had bought some stuff from Veneer Supplies but most of it is self made.
