Poor air quality is often impossible to notice because contaminants are invisible. At other times, contaminated indoor air may have an odd smell. Poor indoor air quality can cause building occupants to become ill. Air quality annual periodic testing rates the cleanliness of the air. Duct maintenance is essential for good air quality.
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.
Several pollutants can collect inside ducts. Mold is the most common. It grows within ducts or on heating and cooling system parts. It may grow on insulation that surrounds ducts. Removing mold from ducts will help, but mold will recur if the cause of growth is never eradicated.
Ducts can also be clogged by other pollutants. They can become infested by rodents or vermin. They can be clogged with dirt and debris released into the home from supply registers. They may be clogged by pet hair or outdoor allergens.
Technicians clean more than just ductwork in a high-quality cleaning. They clean the HVAC components of forced air systems. These include fans, air handling units, and drip pans. These include coils, diffusers, and grilles. These include both supply and return air ducts.
Technicians use specialized tools to dislodge dirt and debris. They vacuum with a high-powered machine. They may apply chemical biocides to the insides of ducts. They may apply chemical biocide to other heating components. They might apply encapsulants that inhibit mold growth. They may apply sealants that prevent the release of dirt or fiber particles.
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.
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.
