If you scrap a window ac unit the window ac unit might bring around $4.00 for scrap metal as is.
But if you take that same window ac apart and separate the materials such as copper, coils etc then you might get around $12.00 to $18.00 from it.
The window ac compressor after opening it up with a chop or some other cutting tool will have around 2 lbs of scrap copper in it which is easy to get out.
Or you can sell the scrap ac compressor as is for a few dollars.
If the ac unit is a central ac unit then you might get around $20.00 to $40.00 as is for the central ac but if you take it apart it might get $50.00 to $70.00 depending on the size of the central air conditioner.
If it's a central air condition you'll likely need to prove where you got it or prove it was yours because of the theft of ac units going around.
