Where can you find a parts list for a Lennox CB29M-31 air handler? I am needing a new evaporator assembly. I would also like to know if there are any cross referance part numbers for other manufactures like Aire-Flow or Ducane that might work with this unit.

Is it a single piece airhandler or a 2 piece? R-22 or 410? Most likely have to get exact replacement. To fit in airhandler. Probably just as cheep to get new airhandler with 5 yr warranty.
