The Air Duct Cleaning Controversy

Should I have my ducts cleaned or not? I hear this question often. The answer is a difficult one. If you are considering having the air ducts cleaned because of a health problem, you should have a physician determine if the cause of the health problem may be related to indoor air quality sources. You must also determine whether the ducts are the cause of the health problems and not mold, pollen, tobacco smoke, combustion products, animal dander or dust mites. Even when contaminants are found in ducts, the source is commonly elsewhere, and cleaning the ducts may only be a small step in the removal of the problem or, as in some cases, increase the problem if done incorrectly.


The duct cleaning industry is expanding to meet demand as the public becomes more aware of indoor air health hazards. The industry uses extensive advertising to encourage individuals to use their services. Individuals wishing to purchase such services should verify that the service provider takes steps to protect individuals from exposure to dislodged pollutants and chemicals used during the cleaning process. This may include the use of a true (3 micron or less) high efficiency air filter (HEPA) on cleaning equipment, indoor air monitoring, and occupants vacating the premises during cleaning.


Keep in mind that regular vacuuming, shampooing, dusting, washing, and filter changing can help limit the need for duct cleaning. Regular maintenance will greatly reduce the chances that harmful pollutants will accumulate in the air ducts and limit the potential of health problems associated with indoor air pollutants.
