This unit had mold on the fan and was severely rusted. We used Fast Attack HVAC System Sanitizer to kill the mold. We removed the flaking rust, and then treated the area with Clean Bond. We rolled V570 to all treated rusted surfaces. We poured a ¼ inch layer of Pancrete in condensate pan. Insulation in fan plenum was treated with BIOFLEX Fungicidal Protective Coating, and Astro-Foil was pin welded in plenums before cold coil.
