Airborne contaminants are a common cause of headaches, fatigue, and respiratory illnesses e.g., asthma. Dust mites and other chemicals, such as those found in carpeting and furniture, often exasperate allergies. Undetected gasses and vapors within the home have in recent years become a major health concern. According to the publication Congressmen Quarterly, “Indoor air can be up to five times more polluted than outside air and up to 1000 times as dirty.”
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 air. These services typically -- but not always -- range in cost from $450 to $1,000 per heating and cooling system, depending on the services offered, the size of the system to be cleaned, system accessibility, climatic region, and level of contamination.
Duct 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. If you decide to have your heating and cooling system cleaned, it is important to make sure the service provider agrees to clean all components of the system and is qualified to do so. 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. PowerBees uses specialized tools to dislodge dirt and other debris in ducts, then vacuum them out with a high-powered vacuum cleaner.
In addition to our normal Duct Cleaning services, PowerBees may suggest certain applications of chemical biocides, designed to kill microbiological contaminants, to the inside of the duct work and to other system components. We might 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. We recommend applying chemical biocides and other treatments only after the system has been properly cleaned of all visible dust or debris.
Note: Use of sealants to encapsulate the inside surfaces of ducts is a different practice than sealing duct air leaks. Sealing duct air leaks can help save energy on heating and cooling bills.
