The EPA ranks indoor air pollution among the top 5 environmental health risks. In Gaithersburg, Maryland, common duct contaminants include mold spores that trigger severe respiratory reactions, dust mites that cause year-round allergies, volatile organic compounds off-gassing from household products, pollen and outdoor allergens pulled inside through your HVAC intake, and pet dander that embeds in duct linings. Your family breathes this recirculated air for up to 22 hours daily.
Just bought a home in Gaithersburg? Standard home inspections in Maryland don’t evaluate duct systems. Your new home could have years of contamination from the previous owner’s pets, smoking habits, renovation dust, or simple neglect. A camera inspection from D&D Chimney Cleaning reveals what’s hiding inside before your family breathes it. Starting fresh with clean ducts is the smartest move a new Gaithersburg homeowner can make.
