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 prevents the occurrence of allergic rhinitis. The Canadian Allergy, Asthma, and Immunology Foundation has data suggesting that the condition afflicts twenty-five percent of Canadians. Conditions that aggravate the problem include outdoor and indoor contaminants, contamination of building fabric, and poor ventilation. Clean ducts prevent all of those conditions.
Several contaminants show up in ductwork. The most likely contaminant is mold. Mold can grow inside ductwork or on the components of heating and cooling systems. It can grow within the insulation that surrounds ductwork. Mold should be removed from ducts, but it will return if the underlying causes are not addressed.
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.
Duct cleaning includes several steps. It includes the cleaning of the HVAC components of forced air systems. Parts include supply and return air ducts. They includes grilles, diffusers, and cooling and heating coils. They include drip plans, fans, and air handling units.
Technicians begin by using custom tools to dislodge particles. They use a high-powered vacuum to remove the particles. Technicians may cover the interior of ducts with a chemical biocide. They may cover other heating components with chemical biocides. They could apply a sealant to prevent the further release of contaminant particles. They could apply an encapsulant to prevent mold growth.
Good technicians have several characteristics. Many have certification from NATE (North American Technician Excellence) or NADCA (National Air Duct Cleaners Association). They provide good references and have clean records with the Better Business Bureau and local consumer affairs organizations. They carry appropriate licensure. They provide estimates that include a timetable if they charge by the hour. They inform homeowners of any possible interruptions in the work schedule.
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.
Technicians should also be monitored as they work. Owners should make sure they protect duct work by sealing and reinsulating holes. Owners should insure that technicians use soft-bristle brushes on fiberglass. Owners should see to the protection of carpet and furniture. Owners should check to see that technicians use either outdoor exhaust or HEPA vacuums. Technicians must inspect for asbestos before starting work, and they should open all access ports for system visibility.
Annual duct cleanings are part of the air quality annual periodic testing process. They prevent the intrusion of mold and other allergens into indoor air. They prevent insects and rodents from living inside ducts. They eradicate pollutants according to established industry standards.
