Good air quality in the home is a crucial component of good respiratory health. In order to maintain healthy air in the home, some experts recommend an annual duct cleaning. A clean ventilation system channels pollutants out of the home, rather than into it. Also, a clean system prevents contamination from microbes, mold, and debris, which may all live inside duct work.

Cleaning a ventilation system includes several steps. Overall, a technician will clean a heating and cooling system, as well as any forced air components. These components include supply and return air ducts, grilles and diffusers, cooling and heating coils, fans, and drip pans. To clean the system, technicians will use specialized tools to dislodge any dirt or debris, and then they will remove the material with a high-powered vacuum.

Technicians may take other steps to improve air quality. For instance, a technician may apply a chemical biocide, both to the inside of ducts, as well as to HVAC system components. In addition, after all visible debris is removed, technicians may apply an encapsulant sealant to the inside of ducts and equipment housings. The sealant is intended to control mold growth, and to prevent the release of dirt particles or fibers.

Good technicians follow established procedures. A good technician will begin by opening access ports, allowing the entire system to be inspected and cleaned. Also, technicians should use vacuum equipment that exhausts outside of the home, or they should use a HEPA vacuum. Good technicians take care to protect household furnishings, and they protect duct work, sealing and re-insulating any holes.

Several contaminants may be present inside air ducts. Mold, for instance, may grow inside ducts, or on heating and cooling system components. If mold is discovered, the service provider should show the mold to the property owner. The owner will have to correct the situation that caused mold to grow, in order to prevent a recurrence.

Ducts may also be clogged with a variety of other particles. When ducts are clogged with dust and debris, the particles are released into the home through the supply registers. Pet hair and outdoor allergens may also be present inside ducts, which may aggravate a homeowner\’s allergies. Additionally, ducts may become clogged with insects, rodents, or other vermin.

Customers must do research in order to choose a good technician. A customer should start by checking a local consumer affairs office, or the Better Business Bureau, for information about complaints. In addition, a customer should ask for references, which insures that past customers were pleased with results. Also, customers should check that a technician has a state license, and that the technician complies with NADCA (North American Duct Cleaning Association) standards and procedures.

Improving air quality inside the home will improve the health of all who live there. For this reason, an annual duct cleaning may be a wise investment for homeowners. Technicians will use specialized equipment to clean any contaminants from the ventilation system. Technicians will also follow professional, established procedures, to prevent damage to the heating system.
