I know the behr is a good system. 
I'm sure that this one was not dealer installed. The lines to the compressor weren't sealed when the compressor was removed. If the compressor was ever present when it was installed.  All the fresh air lines were removed along with the cables, and the glove box is gone. 
  The wiring to the rear heater was moved to the fan switches to the behr and the front blower wiring is who knows where!! This was someone's dream who never even fell asleep!!! 
For a little over a grand I can install a brand new AC, front to back. 
  I'll leave this good system to somebody who has a little more AC knowledge than I have.
