3. Purpose and Benefits

• Vent Cleaning

  • Primarily cosmetic—removes visible dust and buildup from vent covers and nearby duct openings.

  • Can be used between full duct cleaning sessions.

  • Thorough and sanitary: removes dust, debris, allergens, and mold from the entire duct system.

  • Enhances airflow, system efficiency, and indoor air quality.

  • Recommended every 3–5 years, or as needed based on health and environmental conditions.
