How to Inspect Your Air Ducts

1. 1. Turn off the HVAC system before you look inside any duct.
2. 2. Unscrew a return register or vent cover in a room you use often.
3. 3. Shine a flashlight inside and look for dust, debris or mold.
4. 4. Use a camera or your phone to look deeper where the duct bends.
5. 5. Check for gaps, crushed sections or loose connections along visible runs.
6. 6. If you see heavy buildup or mold, book a professional inspection.

These steps cover light maintenance only. For a full system cleaning, book a professional duct cleaning.
