Multiple steps make up the process of cleaning air ducts. Professionals use specialized tools and equipment to dislodge and remove the dust and debris from the ductwork. These tools may include vacuum cleaners, brushes, and blowers designed explicitly for duct cleaning. Other than cleaning the ductwork, professionals will also work on the HVAC unit, evaporator coil, blowers, and other components as needed. If you’re concerned about chemical use, here’s some information. Professional cleaners sometimes resort to chemical biocides and treatments to address any microbial contamination within the air ducts. However, the use of such treatments must be approached cautiously and discussed beforehand. After all, their necessity and safety can differ.
Deciding on an appropriate moment to clean the air ducts isn’t as simple as it seems because there’s no one-size-fits-all approach you can follow. The frequency may depend on several factors, including the presence of pets, inhabitants with allergies or asthma, tobacco smoke, water contamination or damage to the home or HVAC system, and home renovations or remodeling. In any case, the National Air Duct Cleaners Association (NADCA) suggests most homes can benefit from having their ducts cleaned professionally every three to five years.
