Air quality annual periodic testing provides protection against indoor air contamination. Sometimes, indoor contamination produces signs, like odd smells, or illnesses in occupants. Sometimes, it produces no signs at all because contaminants are invisible. Duct cleaning is critical to maintaining clean air in the home.

Duct cleaning addresses many common indoor pollution issues. Around twenty-five percent of the Canadian population has allergic rhinitis according to the Canadian Allergy, Asthma, and Immunology Foundation. Causes of indoor air pollution include contaminants from indoors and outdoors, building fabric contamination, and inadequate ventilation.

Ducts can be affected by several contaminants. The most common contaminant is mold. It can grow inside ducts and on components of the heating and cooling system. It can grow on the insulation surrounding air ducts. It is important, after cleaning ducts, to eliminate the conditions that initially caused mold growth.

Mold is not the only pollutant that can occur inside a duct. Rodents and vermin can infest ducts. Dirt and debris from HVAC supply registers can be released into the home. Pet hair and outdoor allergens can collect inside ducts.

A duct cleaning involves more than just duct work. It may include the cleaning of any HVAC component in a forced air system. These components include supply and return ducts. They may include diffusers, cooling and heating coils, and grilles. They may include fans, air handling units, and drip pans.

Cleaning technicians discharge debris and dirt with special tools. They vacuum dislodged pollutants with a high-powered machine. Some apply a chemical biocide inside of ducts and on top of heating components. Some apply sealants to stop the release of dirt and fibers. Some apply encapsulants that bar the growth of mold.

Look at several factors when choosing a technician. Look for NATE (North American Technician Excellence) or NADCA (National Air Duct Cleaners Association) certification. Check technician references. Check the Better Business Bureau or a local consumer affairs office. Make sure technicians have appropriate licenses. Good technicians should provide an estimate, especially if they charge an hourly rate.

Property owners should ask their technician some important questions. They might ask about their level of experience with a particular HVAC system. They might ask if they comply with NADCA standards. They might ask what steps they take to protect people, homes, and pets from contaminants released during cleaning.

Property owners should monitor technicians’ work. Good technicians open all access ports to make sure the entire system is maintained. They alert homeowners to the presence of asbestos. Their vacuums are either HEPA machines, or their exhaust systems send pollutants outdoors. Technicians use soft-bristled brushes when cleaning fiberglass. They repair any holes in ducts or surrounding insulation. They take care of carpet and home furnishings.

Duct cleaning is a crucial part of air quality annual periodic testing. Good technicians adhere to established cleaning standards. Clean ducts prevent air contamination by mold and other allergens. They also prevent infestations by rodents or other vermin.
