Because mold can be a serious problem for businesses and homes, the National Air Duct Cleaners Association (NADCA) has designated September as Mold Awareness Month to raise the awareness of the hazards of mold. Since mold can be found in all kinds of places throughout buildings, NADCA strongly suggests scheduling periodic air duct inspections and cleanings to get rid of any mold lurking in ductwork or other components in the HVAC system.
In the meantime, what can you do to prevent mold in your buildings? Since mold requires water to grow, it is important to control moisture. Excessive moisture has many causes, especially uncontrolled humidity. Some moisture problems in buildings have been linked to changes in building construction practices during the 1970s, 80s and 90s. Some of these changes have resulted in buildings that are tightly sealed, but lack adequate ventilation, potentially leading to moisture buildup. Moisture problems can also come from:
-Delayed or insufficient maintenance of HVAC or other mechanical systems -Roof leaks -Landscaping or gutters that direct water into or under the building -Unvented combustion appliances
Mold is a pesky problem, but there are ways to prevent it. Be on the watch in your buildings and be sure to have your heating and cooling systems (including the air source supplies) inspected and cleaned.
