Steps to Sanitize Furnace Ducts
1. Turn Off the Power
Before you begin cleaning, make sure to turn off the power to your HVAC system. This is a crucial safety step to prevent any accidents while you work on your ducts.
2. Gather Necessary Supplies
You’ll need a few supplies: a vacuum cleaner with a hose attachment, a brush, a cloth, and a sanitizing solution. Ensure that your cleaning solutions are safe for HVAC systems.

Use the vacuum to remove loose debris from the ducts. Follow up with a brush to dislodge any stubborn dirt. Wipe down the inside of the ducts with a damp cloth soaked in the sanitizing solution.
4. Replace Filters
Always replace your HVAC filters after cleaning the ducts. This ensures that any debris caught during the cleaning process does not recirculate in your home.
