Clean air ducts are the foundation for good indoor air quality. Homeowners and business owners want to breathe clean indoor air for themselves, their guests, employees, and customers. Over several years, air ducts can also become contaminated with mold, fungi, and bacteria, as well as dust. Routine HVAC doesn’t remove them. Proper removal with equipment like Rotobrush’s air duct cleaning machines and systems is one way to improve indoor air quality. Series offered are BrushBeast, aiR+, and aiR+XP,. All units are offered in Bronze and Silver Packages.
