Cleaning the air ducts in your house can make a noticeable difference in air quality and HVAC system efficiency. Many homeowners wonder if they can handle this task as a DIY project, and the answer is yes—with some preparation, patience, and the right tools! Here’s a step-by-step guide:

1. Gather Supplies: You’ll need a screwdriver, brush, vacuum with a long hose attachment, microfiber cloths, and a new furnace filter.
2. Turn Off HVAC System: For safety and to prevent more dust from circulating, turn off your heating or cooling system at the thermostat.
3. Remove Vent Covers: Use a screwdriver to carefully remove all wall, floor, and ceiling vent covers. Soak them in warm soapy water to remove dust and grime.
4. Loosen Dust Inside Ducts: Gently tap accessible ducts with a brush to loosen dust that clings to the interior walls.
5. Vacuum Inside Ducts: Insert the hose attachment as far as possible, vacuuming thoroughly to remove dust, debris, and any visible mold. Repeat for each opening.
6. Wipe Down Accessible Surfaces: Use a damp microfiber cloth to clean the vent covers and any areas you can reach inside the ducts.
7. Replace Vent Covers and Filter: Dry the vent covers and reattach them, then replace your furnace filter to ensure clean airflow.
