Cleaning air ducts is necessary because it reduces dust in your house and keeps the indoor air fresh. According to the Environmental Protection Agency (EPA), the light dust in ductwork is less hazardous than contaminants stirred up by cooking, cleaning, and smoking. Moreover, rodents, insects, and other vermin can infest the ducts. The air duct cleaning process can be done by professionals or you may choose a DIY solution. If you are not sure, consulting with the experts in air duct cleaning in Rocklin can help you.

Here are the steps to perform duct cleaning.

 1. Shut off the HVAC Power

Turning off the thermostat is necessary for safety. Leave the fan on to let the airflow dislodge and move the dust. Wearing eye protection to prevent your eyes from falling dust or debris is necessary while working with overhead air vents.

 2. Remove Vent Covers and Wash Them

Remove the vent covers with a screwdriver. You can clean them in a dishwasher or a hand-rinse would be sufficient. Set them aside to dry. You can use a vacuum to clean the surface if it’s too dusty.

 3. Clean from Inside

Insert the vent brush into the duct to clean it along the interior surfaces. Additionally, tapping exposed ductwork a few times will help loosen debris. Finally, extend the hose of your vacuum cleaner to clear the debris. If you have a shop vac, you can use an extension hose to reach deeper into your ductwork. After vacuuming, use a damp microfiber cloth to clean the vent's interior.

4. Replace Air Filter

Air filter replacement is inevitable to keep the indoor air clean. The dust in your house will reduce if you get a new filter. A clogged filter restricts airflow to the fan, increasing the blower motor temperature and shortening motor life. Smart homeowners know that cleaning or replacing furnace filters at least once a month will help to reduce dust in their houses.

5. Finish Up

Turn the thermostat on after reinstalling the vent cover. For 30 minutes, let your system run to filter any remaining dust loosened during cleaning.


Air duct cleaning may look like a simple process but requires rigorous effort and caution. The DIY approach can work provided you know the appliance and the best equipment. It is worthwhile to hire a professional to clean your ducts if you find or suspect mold growth, rodent or insect infestation or if you're concerned about contaminated airflow in your house.
