Every yard I've been to wants a computer generated receipt for the ac unit but they never ask me about the fridges which also hold Freon. And even the few times when i did not have time to take the Freon out of a fridge i can see them breaking the fridge in the press and of course the lines break and the Freon goes up in the air. You can stand there and watch them throw even ac units in the press, same thing. And these are not small yards, i'm talking about commercial yards where even the county and waste management bring there stuff for money, i see the trucks almost everyday pulling in.
