I'm wondering if there is a place I can go to have several window A/C and some dehumidifiers emptied of the refrigerant? If posible I would like to recycle the metals when empty. I'm in Adams,MN. I have found that there are a few homeowners out there that just vent them into the air so they can reclaim the metals. It would be a good thing if I can point them in the right direction including myself.
