Whole-system duct and dryer vent check with before-and-after photos - you see exactly what came out of your vents
That "$99 whole-house special" is a bait ad - the real number appears once they are in your hallway, or the "clean" is a shop-vac at the register. We photograph the inside of your ducts before and after instead.

AfterAir Duct Cleaning Company in El Sobrante, CA
Air duct cleaning in El Sobrante typically runs $350 – $650 for a whole-home system, with most jobs completed in a single visit. What sets this market apart is the combination of aging 1950s – 1970s ranch homes, steep hillside terrain, and seasonal wildfire smoke intrusion that pushes debris deeper into ductwork than in flatter East Bay cities. We’re Hollis Air Duct Cleaning, and our crews handle these conditions with rotary brush systems from Rotobrush and negative-air machines from Nikro, the same tools commercial crews use. Call us at (361) 326-5060 for a free estimate.
Why El Sobrante Homes Are Different
El Sobrante sits in the San Pablo Valley, surrounded by oak woodlands and eucalyptus groves that release heavy pollen each spring. That pollen doesn’t stay outside. It gets drawn into attic and crawlspace duct runs, then distributed room to room through systems that were never designed for modern filtration.
The housing stock compounds the problem. Most homes are single-story ranch-style builds from 1950 to 1975, many with original galvanized steel ductwork that’s now rusting internally. We’ve opened systems in the hillside subdivisions off Appian Way and found flexible duct retrofits packed with dust, rodent debris, and ash residue from wildfire events. The El Sobrante Ridge and properties near San Pablo Dam Road are especially prone to smoke intrusion from prescribed burns and wildfires in the Wildcat Canyon area. That ash leaves a persistent odor that surface cleaning won’t touch. The full system needs sealing and HEPA filtration to remove it.
Access is another factor. Steep lots mean crawlspace entries at odd angles and attic hatches in tight closets. Our technicians carry the right extension gear and follow The Garrison Code on every job: arrive inside the window, price in writing, leave the site clean.
Our Main El Sobrante Services
El Sobrante homeowners call us for three core services. Each has its own page with detailed pricing and process information.
Air Duct Cleaning in El Sobrante
We clean the full supply and return network with a Rotobrush rotary brush system that scrubs the interior walls of galvanized steel or flexible ductwork, paired with a Nikro negative-air machine that pulls dislodged debris out of the house entirely. In El Sobrante, we pay special attention to smoke residue from wildfire events, which bonds to metal duct walls and recirculates every time the HVAC runs. Air Duct Cleaning in El Sobrante
Dryer Vent Cleaning in El Sobrante
Dryer vent blockages are common in El Sobrante’s older homes where original vent runs were routed through long crawlspace paths or steep exterior walls. We clear the full run from dryer to termination, test airflow with a manometer, and verify the exterior hood opens fully under pressure. Dryer Vent Cleaning in El Sobrante
Duct Sealing in El Sobrante
Sealing is the fix for El Sobrante homes pulling in wildfire smoke through gaps in attic or crawlspace duct joints. We apply duct sealing mastic to accessible joints and connections, then pressure-test the system to confirm leakage reduction. This stops unfiltered outside air from entering the system and protects indoor air quality during smoke events. Duct Sealing in El Sobrante
