Duct Cleaning

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 encapsulates) 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.
