HVAC Duct Cleaning in El Dorado Hills, CA

Why duct cleaning comes up so often here

The soil does most of it. Decomposed granite breaks down to a fine gray powder. Grass fields dry out by June and stay dry. That dust rides in through the return all summer, settles in boots, and loads the evaporator coil. Spring adds oak and grass pollen. Smoke seasons leave fine ash sitting in plenums long after the air clears.

Construction is the other source. Foothill tract homes from the 1990s and 2000s often still hold drywall dust and sawdust in the supply runs. Nobody cleaned them after framing. Insulated flex duct in those attics sags between joists, kinks at turns, and chokes the far bedrooms. Boots pull partway off the register. Then the system breathes attic dust, loose insulation fiber and rodent debris straight into the house.

Older valley-floor homes are different work. Galvanized trunk and round takeoffs. Original internal fiberglass liner, now shedding. Crawlspace metal that sweats and smells like mildew. Brushing a failed liner just releases more of it. That duct needs replacement, and we will say so rather than clean it twice.

Roughly every three to five years suits most households. Tighten that to two or three with pets, open grassland nearby, allergy sufferers, or a heavy smoke year.
