6 Common Air Duct Cleaning Methods

Mechanical Agitation

Uses brushes, compressed air nozzles, or hand brushing to dislodge debris. HEPA-filtered vacuums prevent cross-contamination.

Power Vacuuming

Powerful suction removes stubborn dirt. Truck-mounted systems handle large volumes of air. Not suitable for delicate ducting.

Negative Pressure

Creates a vacuum to draw out contaminants. Often combined with air sweeping and compressed air for better results.

Steam Cleaning

Uses pressurized steam to clean ducts. Ideal for older HVAC systems, but can damage modern electronics.

Chemical Cleaning

Direct application of chemicals to break down contaminants. Effective for microbial growth; may cause allergic reactions or environmental harm.

Air Duct Sanitizing

Uses natural or hospital-grade antimicrobial agents. UV sanitizers installed in ducts neutralize bacteria and mold. These methods ensure your HVAC system stays clean and efficient.
