    A hurricane, tornado or flood is devastating to businesses, schools, homes, streets and entire communities. We see this devastation first-hand across the U.S. each hurricane season, we feverishly work to re-build these communities back to their splendor. In this surge of construction has also come a surge in home sales and home improvements. Upon any new purchase on the in a hurricane or flood zone, there needs to be a post-storm-mind-set, all homes and businesses should be thoroughly inspected with special considerations we may not have previously had. One of these being “was the HVAC system cleaned and inspected after our flood?” Considering the cleanliness of the HVAC system should be a top priority because that system will be circulating the conditioned air throughout the structure. If a dirty HVAC system has been contaminated by water and humidity, microorganisms can grow and multiply as soon as 48 hours after contamination.

    DUCTZ knows this first-hand as in the case of any flood, DUCTZ works closely with restoration companies to ensure that the HVAC system is also inspected, cleaned and restored with the rest of the property.

    According to the Center for Disease Control, CDC;

    “Mold Prevention Strategies and Possible Health Effects in the Aftermath of Hurricanes and Major Floods; Cleaning a Heating, Ventilating, and Air Conditioning System”:

    All surfaces of an HVAC system and all its components that were submerged during a flood are potential reservoirs for dirt, debris, and microorganisms, including bacteria and mold. In addition, moisture can collect in areas of HVAC system components that were not submerged (e.g., air supply ducts above the water line), and this also can lead to the growth of microorganisms. Therefore, all flood water‐contaminated and moisture‐laden components of the HVAC system should be thoroughly inspected, cleaned of dirt and debris, and disinfected by a qualified professional. CDC has prepared recommendations for professionals to help ensure that floodwater‐contaminated HVAC system components are properly cleaned and remediated (21). If HVAC systems are not properly cleaned and disinfected to prevent the dissemination of mold and other debris throughout a building, bioaerosols of mold and other microorganisms might exists and can cause a variety of adverse health effects to the building’s occupants. Ensure that the HVAC system is shut down before any remedial activities.”

    Therefore, 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 with a specific detailed plan for the exact location.

    Please call DUCTZ if you suspect that there may be microbial growth within your HVAC system, or if your HVAC system was compromised during or after the flood. DUCTZ offers free estimates as well as a PICTURE PERFECT REPORT, a report of before and after photos of your project to ensure a job well done to your specifications.
