Heating and air conditioning ducts get dirty and contaminated over time. Depending on the environment, contaminants can be mold, mildew, fungus, dust, vermin, dust mites, pollen, and other allergens and pollutants. A professional air duct cleaning in Shrewsbury MA will remove all these sources of poor air quality and reduce power consumption at the same time.
During the cleaning process, which involves brushing and vacuuming, the cleaning company may want to use chemicals to ensure a thorough cleaning. These are duct-cleaning biocides and can be used to clean the coils, blowers, blower casings, and other areas where deep grime and other contaminations have built up. They can assist in removing unpleasant odors well.
An article by the NADCA discusses the use of chemicals for cleaning a home or business’s air duct systems.
There are possible reactions associated with the use of chemicals so the cleaning company may ask for the residents or staff to leave the building during the cleaning process.
A reputable air duct company will advise the owner of the possible risks and once fully understood, have the owner sign a release before application. The owner can opt to not have the chemicals used. If, during the preliminary inspection, a rodent infestation was found, the contractor must hold a pesticide applicator’s license to address the situation.
The cleaning biocides used during an air duct cleaning in Shrewsbury MA process may include:
Antimicrobial Pesticide: A chemical that is used to control microbial pests such as fungi, mold, viruses, and bacteria. Regardless of what the chemical composition is if the chemical is used as a pesticide it is considered as such and must be an EPA-registered product.
Sanitizer: It is a substance or olio of substances that will effectively kill 99.9% of all bacteria on a surface. The products used are also EPA-registered and are basically defined as products that will bring the level of bacteria to a level considered safe by the public health department.
Disinfectant: This is an agent that can eliminate infectious microorganisms but not bacterial spores. They are most useful in the fight against fungi and viruses.
During the air duct cleaning in the Shrewsbury MA process, the chemicals are sprayed, wiped on, or applied as a fog. The method of application is always on the chemical container and must be followed by the contractor.
The use of chemical biocides can help in reducing the risk of future microbial growth. The overuse of these chemicals can lead to needless overexposure and at times poor application can be a waste of money.
