Property owners, managers, and tenants should read the list of the top 100 mold illnesses at www.moldinspector.com, a mold information website that has been online since 1999. Detailed information about air conditioning mold is available at www.airconditionermold.com. Mold expert Phillip Fry is author of the ebook Mold Health Guide.
Fry and Maglanoc point out the following problems with cooling equipment and systems:
1. As for swamp coolers, which utilize large amounts of water to evaporate for the cooling effect caused by water evaporation, the swamp coolers themselves are often heavily mold-infested because of the wet condition inside a swamp cooler and the continual intake into the evap cooler of large number of airborne mold spores and mold food (organic dust in the air). Airborne mold spores from the evap cooler’s mold colonies are then distributed throughout the house or building in the discharge of cooled air from the cooler.
2. Window or wall-installed air conditioners also have a wet interior environment with plenty of incoming mold spores and organic dust to drive significant mold growth inside the units. To prevent window air conditioners from being mold factories, the units need to be removed and thoroughly cleaned inside every three months to get rid of accumulated mold growth and dirt/organic dust.
3. Central heating, ventilating, and air conditioning (HVAC) equipment and ducts are often mold-contaminated because of the wet environment inside the HVAC system, leaking and overflowing condensation pans (often from a stopped up or plugged condensation drain line), and the continual intake of airborne mold spores and organic dust.
Fry and Maglanoc recommend that Arizona, California, and Nevada air conditioners, central HVAC systems, and swamp coolers have their outward air flow tested at least annually to determine if the units have elevated levels of toxic mold spores.
In addition, the environmental hygienists recommend a careful visual inspection inside the units and HVAC ducts and frequent cleaning---every three months for window or wall units and at least annually for central HVAC air supply ducts.
