The answer to 'how does duct cleaning work' is that duct cleaning is the process of removing dirt, dust, and other debris from the ductwork in your home's HVAC system. This is typically done by using specialized equipment, such as high-powered vacuums and brushes, to dislodge and extract the accumulated material from the inside of the ducts. The goal is to improve the efficiency of your HVAC system, reduce the amount of dust and allergens circulating in your home, and potentially extend the lifespan of your system.
Duct cleaning is usually performed by professional HVAC technicians, as they have the necessary equipment and expertise to do the job effectively and safely. They will first inspect your ductwork to assess the level of contamination and determine the best approach. Then, they will use specialized tools to access the interior of the ducts, loosen the debris, and vacuum it out. The process may also involve the use of antimicrobial treatments to help prevent the growth of mold and bacteria.
