As a general rule, the National Air Duct Cleaners Association (NADCA) recommends cleaning air ducts every 3 to 5 years. With certain methods, that cleaning recommendation can be extended by 6 to 8 years. Air ducts, like any other air conditioning system, require regular cleaning to ensure maximum efficiency and optimal air quality. In some environments, the need for commercial air duct cleaning is more urgent.
Food manufacturers, for example, must have their ducts cleaned quarterly, biannually, and annually due to food particles entering their systems, causing mold and pest problems. The same is true for manufacturing operations that create risks of combustible dust. For homes where occupants suffer from allergies or asthma, air ducts may need to be cleaned more frequently. Dust, pollen, and other contaminants that accumulate in air ducts can aggravate these conditions.
Therefore, experts suggest cleaning the air ducts every two to three years in these cases for optimal prevention of allergies. Pets bring joy and companionship, but they also bring extra dirt and dander into the home. Pet hair and dander can build up in air ducts over time, contributing to poorer air quality and possible allergies. If you have pets, consider cleaning the air ducts every two to three years. When it comes to determining how often you should clean your duct systems, there are a few factors that influence the decision. Every 3 to 5 years is a standard recommendation, but you may want to consider doing it more often depending on certain factors.
The advantages of duct cleaning are that it removes all dirt from the duct system and not just the last few meters that the owner can remove with a vacuum cleaner. To see the entire interior of the ducts, a video inspection by an air duct cleaning company is necessary.
