Clean Ducts = Cleaner Air In Your Home

Duct cleaning usually involves the cleaning of various heating and cooling system components, including some or all of the following: the supply and return air ducts and registers, grilles and diffusers, heat exchangers heating and cooling coils, condensate drain pans (drip pans), fan motor and fan housing, and the air handling unit housing.

If not properly maintained, these components may become contaminated with particles of dust, pollen or other debris. If moisture is present, the potential for mold is increased and these spores may be released into the home's living space. Some of these contaminants may cause allergic reactions or other symptoms in people if they are exposed to them. Methods of duct cleaning vary, although standards have been established by industry associations concerned with air duct cleaning. Typically, a service provider will use specialized tools to dislodge dirt and other debris in ducts, then vacuum them out with a high-powered vacuum cleaner.

In addition, the service provider may propose applying chemical biocides, designed to kill microbiological contaminants, to the inside of the duct work and to other system components. Some service providers may also suggest chemical treatments to cover the inside surfaces of the air ducts and equipment housings because they believe it can control mold growth or prevent dirt particles or fibers from getting into the ducts.
