Welcome aboard! The Canon AE-1 is a great little camera. some of the Canon FD lenses are lovely bits of glass too. Tell me - does your AE-1 have the characteristic Canon 'cough' when you release the shutter?
I had to look up "Canon cough" and found a Youtube link to listen to. No, the camera just makes a loud click and does not make that squealing noise when the mirror moves. It takes beautiful photographs with the 50mm f/1.4 and 85mm f/1.8 that I have.
