Duct Cleaning Periodical Testing For Businesses

Good times for duct cleaning periodical testing include the summer, before the winter heating season, and winter, before the summer cooling season. Clean ducts enhance the function of all heating and cooling systems, and also improve the quality of indoor air. Good indoor air quality may contribute to better overall health, for employees, and less missed work, keeping the business productive year-round.

Pollutants and allergens often take up residence inside duct work. Dust and debris, along with microscopic particulates, accumulate in ducts, and may then be released back into the building. Also, mold may grow on HVAC components, in insulation surrounding ducts, or inside the ducts themselves. All of these particles are allergens, which lead to not only allergic reactions, but also to upper respiratory infections.

All HVAC components are cleaned during an appointment. Technicians use specially-designed tools, which clear out dirt and debris, before using a powerful vacuum to remove what remains. Business owners, by the end of an technician's visit, will not only have clean ducts, but also clean diffusers and grilles, clean HVAC coils, clean fan motors and housing, clean drip pans, and clean air handling unit housing.

Sometimes, vacuuming does not remove all areas of concern. In these cases, technicians may use chemicals, such as a biocide, which is capable of killing mold, both within ducts and on system components. Technicians may also paint the insides of the ducts, and the equipment housings, with an encapsulating sealant. When visible debris is gone, the encapsulating sealant pins down invisible fibers and dirt particles, and provides additional mold growth prevention.

Due diligence is required, before choosing a cleaning company. Business owners should check with available agencies for consumer affairs, and possible a Better Business Bureau office, to make sure the company has a satisfactory record. Also, business owners should check for certifications, from NATE (North American Technician Excellence) or NADCA (North American Duct Cleaners Association).

A poor duct cleaning may worsen indoor air pollutants. Therefore, business owners must make sure that technicians are qualified, before making any commitment. The appropriate technician will have commercial experience, as well as all required state licenses, and maybe certifications. The appropriate technician will also be able to provide a well-calculated time estimate for work performed, and plans to prevent indoor contamination.

Business owners should look for certain signs of a quality job. The best technicians use HEPA vacuums, or vacuums which exhaust to the building's exterior, during a cleaning. Great technicians will also protect the HVAC system, and will take time to repair and re-insulate any holes in ducts. All access ports will be opened by a competent technician, so that the business owner knows that the entire HVAC system has been inspected and cleaned.

Duct cleaning periodical testing may prevent instances of allergic rhinitis, a condition which affects twenty-five percent of the Canadian population. Good indoor air quality, in addition to more efficient HVAC system performance, are both good reasons for setting an appointment for a cleaning. Employees will appreciate the improved environment, and business owners will appreciate the savings on energy costs.
