Duct cleaning has never been shown to actually prevent health problems. Neither do studies conclusively demonstrate that particle (e.g., dust) levels in homes increase because of dirty air ducts. This is because much of the dirt in air ducts adheres to duct surfaces and does not necessarily enter the living space. It is important to keep in mind that dirty air ducts are only one of many possible sources of particles that are present in homes. Pollutants that enter the home both from outdoors and indoor activities such as cooking, cleaning, smoking, or just moving around can cause greater exposure to contaminants than dirty air ducts. Moreover, there is no evidence that a light amount of household dust or other particulate matter in air ducts poses any risk to your health.
As certified technicians, clients are assured that the workers are all mindful while conducting commercial air duct cleaning. Their professionals follow the strict guidelines of the National Air Duct Cleaners Association (NADCA) in inspecting your ventilation system. They will first inspect your HVAC system and will evaluate its conditions. They will also discuss the possible options with you.
