It would be nice to sell your reclaimed/recovered refrigerant, but Johnstone charges to take back your tank and exchange it for an empty, almost as much as buying a new tank. I have recently seen where another distributor is saying that they will exchange for free but as yet I have not tried to see how that works out.
Are there places that will buy back the recovered refrigerant?

Yes, they will charge a deposit for their 250, 500, or 1,000 pound tank. you put your recovered refrigerant in their tank. then when its full. You call them and they deliver another empty tank, pick up the full one. And then after they reclaim it they pay you. or some will sell you the reclaimed back.
I am not there but I bet they are not checking s/c if they are 30-40deg s/c when you come back. I guess if it is really 90 inside when they do it its possible but I havent seen on any charts to check w/b to charge a txv sytem. there is just s/c to psig. But it makes sense if its boiling inside expecially a new, humid hot house you would almost have to come back no matter what, anybody know of any procedures to charge when its that hot?
