90% was in the attic... Of course the trap froze. So lets put it in a bulkhead, and unhook 75% of the ductwork. Just leave the filter door off and put a filter frame on the front of it.
Had two 6" runs and a 8" run coming off the coil cabinet. Cycled on the high limit.
Ripped it all out and put in an up flow system and ran all new ductwork in the attic. A lot of fun trying to find all the old ceiling diffusers buried in the insulation.
Attic had a bunch of these weird looking things laying everywhere!
