Most people are now aware that
indoor air pollution is an issue of growing concern and increased
visibility. Many companies are marketing products and services
intended to improve the quality of your indoor environment.
Duct cleaning refers to the
cleaning of various heating and cooling system components of forced
air systems, including the following:
-
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
-
Air handling unit housing
If not properly installed,
maintained, and operated, these components may become contaminated
with particles of dust, pollen or other debris. If moisture is
present, the potential for microbiological growth (e.g., mold) is
increased and spores from such growth 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.
Failure to clean a component
of a contaminated system can result in re-contamination of the
entire system, thus negating any potential benefits. Methods of duct
cleaning vary, although standards have been established by industry
associations concerned with air duct cleaning. California Air Duct
Cleaning uses specialized tools to dislodge dirt and other debris in
ducts, and then we vacuum them out with a high-powered vacuum
cleaner.
In addition, we may propose
applying chemical biocides, designed to kill microbiological
contaminants, to the inside of the duct work and to other system
components. We may also suggest applying chemical treatments
(sealants or other encapsulants) to encapsulate or cover the inside
surfaces of the air ducts and equipment housings because we believe
it will control mold growth or prevent the release of dirt particles
or fibers from ducts.
