For disinfection, I recommend using a fogger and an organic sanitizer, like one made out of tea tree oil. The best practice is to power your air handler off, open the evaporator curl compartment, and spray the evaporator coil and condensate bleed with the sanitizer. Just be conscientious not to wet the electrical compartment.
