I would check with your local scrap yards about the laws on scrapping A/C units. In Florida you have to have a receipt for a new a/c unit in your name that you had installed within the past 90 days, or you have to have a company letterhead from an A/C company that they gave the material to you and you are allowed to scrap the material and able to receive the money for it, and it has to be dated within the past 90 days. but it all depends on you local and state laws.
