That's good news. I'm glad you were able to get things cleared up.
I had a little time a few days ago so i tore one of the ac fan motors apart to see how much copper was in it. It was about 1/3 of a pound. It's really up to you to decide if you want to break them down or sell them whole.
grey truck has a sealed unit scrapping video up on youtube. It's one of the best ones i've seen. It might be worth a watch if you are looking at doing 160 of them. Don't know about you but i'm always looking for different ways of doing the job. Once in awhile you hit on something that makes the job go easier.
