I'm not sure if this is the right area to post this general question. I get a descent supply throughout the year of PCB's from furnaces and various HVAC equipment. Is there enough silver(or any silver) in these types of boards to attempt recovery? I know there is little to no gold in these board. If it is worth while I can probably get my hands on more from other shops.

Go after the silver in contactors for the fans and compressors, IDEC . Every now and then you might find a microrelays on boards .
I have been contemplating building a little gizmo to tear the boards down and hopefully in theory almost powder to make any precious metals easier to refine. Is that a waste? I will definitely keep my eyes out for the motors, I always grab the aluminum ends before sending them down the road.
Welcome to us.
There is likely not much Silver on the boards themselves as the tracing on/in the boards are usually Copper.
The relays and some components may have values in them.
