@LunadelobosIAMTHEDRAGON HVAC specialists have tools and equipment that cleans the vents. I hired a vent cleaner when I bought a fixer upper house in Michigan a few years ago, and they cleaned bird feathers and loads of mouse turds out of the ventilation system.

HVAC specialists seal off the vents, then use a high powered vacuum to clean out the mold. THEN they address preventing future growth with a chemical treatment.
