Where do all the used air conditioning units (Trane) and parts go to??
 

Are the salvageable parts sold to supply companies in the area? Looking for Trane parts... Any ideas?

Here is a website into that sells Trane parts, but they are probably new parts.

Just a moment...

I doubt that there is much of a market for used HVAC parts because most new systems come with a 10-year parts warranty. Also, who wants to pay a technician top dollar to install a used part?
