Air duct cleaning removes accumulated dust, dirt and debris from the ductwork connected to your HVAC system. Woodard provides professional air duct cleaning services for homes and businesses throughout the St. Louis area.

Signs that your air ducts may need cleaning include excessive dust or debris inside the ductwork, particles coming from supply registers, visible mold growth inside hard-surface ducts or HVAC components, or evidence of rodents or other pests in the system. If you’re unsure about the condition of your ductwork, a professional inspection can help determine whether cleaning is appropriate.

Woodard’s air duct cleaning process uses professional equipment to loosen and remove accumulated dust, dirt and debris from your HVAC system. Our process includes:

1. Inspect & Prepare: We start by inspecting your HVAC system and ductwork, noting any areas of concern and protecting the surrounding work areas as needed.

2. Contain the System: We seal supply and return vents to help keep loosened dust and debris contained during the cleaning process.

3. Create Negative Air Pressure: We use specialized equipment to create powerful suction throughout the duct system, helping capture and remove debris as it is loosened.

4. Clean the Ductwork: We clean the supply and return ductwork using professional brushing and air-whip equipment to loosen and remove accumulated dust, dirt, pet hair and other debris.

5. Clean System Components: We clean accessible HVAC components included with your service, along with supply and return vents, before carefully reassembling the system.

6. Sanitize & Deodorize: After debris has been removed, we apply an approved sanitizer and deodorizer throughout the supply and return system to help address remaining odors and contaminants.

7. Inspect & Review: We check airflow and system operation, clean up the work area, and review the completed service with you, including before-and-after photos and any notable findings.

Woodard generally recommends having your air ducts cleaned every 3–7 years, depending on your home and lifestyle. Homes with pets, open windows or other factors that contribute to dust and debris buildup may benefit from more frequent cleaning. A professional inspection can help determine when cleaning is appropriate for your system.

Air duct cleaning removes accumulated dust, dirt, pet dander and other debris from your ductwork. While keeping your HVAC system clean can remove these materials from the system, air duct cleaning should not be considered a treatment for allergies or other health conditions.

Most residential air duct cleaning appointments take 3–6 hours, with an average of about 4 hours. The exact time depends on the size of your home, HVAC system and condition of the ductwork. Our technicians will need access to your HVAC equipment and supply and return registers throughout the home.

Woodard recommends checking and replacing your HVAC filter after air duct cleaning. If you normally use a high-end filter, consider installing a less expensive filter immediately after cleaning. After 7 days, discard it and install your normal filter.

Yes. The condition of your HVAC system and ductwork can affect whether air duct cleaning can be performed. If our technicians find water in the system or flexible ductwork that is damaged or in poor condition, cleaning may not be appropriate. We’ll assess the condition of the system and explain any concerns before proceeding.

Keeping the dryer vent clear can help your dryer operate more efficiently and prevents lint from restricting airflow. Ask about adding dryer vent cleaning to your air duct cleaning service.
