Many people don’t think about duct cleaning, but it’s vital for removing allergens and other contaminants from workplaces, schools, and homes. Central air heating, ventilation, and air conditioning (HVAC) systems circulate warm or cool air through ducts, accumulating dust and debris despite using air filters. Over time, dust and other debris settle on the bottom of the duct and become stuck to the walls due to humidity, requiring a duct cleaning company to remove this material.
Pro Air Duct Cleaning Equipment released a video, “Air Duct Cleaning Equipment Explained (2022),” that describes the equipment they sell. The footage includes valuable examples of the equipment in action for those unfamiliar with how the duct cleaning process works.
Significantly, they distinguish between the negative air and push or pull duct cleaning methods. Their products follow the negative air method, which requires substantially less costly equipment than the push and pull method.
The negative air method involves inserting a long plastic tube into the air duct. A nozzle at the end of the tube blows air backward, sending dust back to the vent, where the materials are captured and removed. The method also uses a hose with a whip head attachment that strikes the duct walls to dislodge debris. The combination results in an effective and efficient duct cleaning process.
