This ensures safety and prevents circulating debris during the process.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"step-2-unscrew-and-remove-vent-covers\"><strong>Step 2: Unscrew and Remove Vent Covers<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Use a screwdriver to remove vent covers and registers. Clean them using soapy water and a brush, then set them aside to dry.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"step-3-loosen-dust-with-a-brush\"><strong>Step 3: Loosen Dust with a Brush<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Use your stiff-bristle brush to dislodge dust and debris from inside the duct walls. Reach in as far as possible.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"step-4-vacuum-thoroughly\"><strong>Step 4: Vacuum Thoroughly<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Insert the vacuum hose into the duct and slowly move it around to suck up loose particles. A shop vac or HEPA vacuum is best for capturing fine particles.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"step-5-wipe-interior-duct-walls\"><strong>Step 5: Wipe Interior Duct Walls<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Using a damp microfiber cloth, carefully wipe down the interior surfaces of the ductwork. Repeat until the cloth comes out clean.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"step-6-replace-the-furnace-filter\"><strong>Step 6: Replace the Furnace Filter<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Your filter has likely trapped dust during the process.
