The rain in the Midwest continues, and many homes and businesses are experiencing damage caused by flooding from the heavy rainfall. Once the restoration process begins, it’s important to remember where hidden mold can be found after a flood: In the HVAC system.
According to the Centers for Disease Control and Prevention, even if the HVAC system isn’t submerged, moisture can collect on components of the system such as air supply ducts, which can promote the growth of microorganisms. The CDC recommends that all components of the HVAC system that were contaminated with flood water or moisture should be thoroughly inspected, cleaned of dirt and debris, and disinfected by a qualified professional.
If you know or suspect that there is mold in your building’s HVAC system, turn it off to avoid spreading mold further through your building, and have the system cleaned as soon as possible. Mold can be found in condensate pans, air handlers, blowers, plenums and other components, so be sure to have these cleaned along with the ductwork where mold is found.
