JB / Keith Air Duct Cleaning
I am still working on getting my P337H airworthy and today's project was cleaning up the Air-conditioning system. If you have one of these systems installed, as a heads up, one might want to get into the ducting and the blower box that has the evaporator in it. I believe mine was installed in 1985, I do not think anyone has looked in there since. The ducting and box on mine were totally black, I am assuming mold of some sort, as you can see from the pictures. A little dawn and elbow grease solved the problem.
