NYC Air Conditioning and Vent Cleaning has been serving New York City since 1972 using their patented rotobrush duct cleaning technology. Their method removes bacteria, mold, and dust mites from ducts using vacuums and brushes without harsh chemicals. Problems can arise when ducts develop breaches or moisture buildup allowing unfiltered air or mold growth inside ducts. Technicians inspect the entire HVAC system, including testing air quality and checking for issues behind walls or under floors before determining if cleaning is needed. Once issues are addressed, their crew uses rotobrush technology to safely clean every inch of ducts without chemicals that could remain and be inhaled, avoiding health hazards.
