Air Duct Cleaning
Most people are now aware that indoor air pollution is an issue of growing concern and increased visibility.
Duck cleaning generally refers to the cleaning of various heating and cooling system components of forced air systems, including 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 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.
