The first step in any duct cleaning is the removal of dust. This may involve the technician inserting a specialized vacuum and brushing system into the air ducts to sweep it out from the inside. Another technique involves connecting a powerful vacuum to one end of the ducting and an air blower to the other end after sealing off all the other vents. These techniques can remove dust and debris that might be clogging the air vents.

If the air ducts are infected with mold, it may require specialized treatment to remove. In some cases, controlling home humidity and scrubbing out the vents may be sufficient to end the infestation and prevent further problems. Particularly bad cases may require the use of biocides designed to kill mold and other microorganisms that may be present in the vents. Care should be taken before using any of these products, since the action of the air conditioner may carry the agents out into living areas.
