We use the NADCA-standard negative-air method with agitation tools to physically remove buildup — not just mask it.
Cleaner, Healthier Air
Removing dust, dander, and allergens from your ducts means fewer irritants recirculating through your home.

I hired Armstrong to clean my ductwork. They were great from start to finish! Well detailed quote. The service team was on time, courteous, thorough and cleaned up after themselves. They even provided before and after pictures of their work. I would recommend them to anyone!
