We cleaned the air ducts in this Longwood home, which had a significant amount of dust buildup. The before-and-after photos clearly demonstrate the effectiveness of our vacuum trucks in thoroughly removing accumulated debris. We tape or block the vents to give us more suction when cleaning. This also helps protects the home. At the conclusion of the cleaning process, we apply a sanitizing fog throughout the system to ensure a hygienic finish. Air ducts should be cleaned every 3 years to prevent excessive dust build up and improve indoor air quality.
