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 Blackhawk, CA
Air duct cleaning in Blackhawk, CA typically runs $400 – $900 for a whole-home system, with most executive homes falling in the $550 – $750 range due to larger square footage and multi-zone HVAC setups. We’re Hollis Air Duct Cleaning, and we’ve learned that Blackhawk jobs aren’t like standard suburban calls. The combination of well-water mineral dust, dry-grass landscaping particulate, and aging flex ductwork in unconditioned attics means we bring Rotobrush rotary systems and Nikro negative-air machines to every home, not lightweight portable units. If you’re ready to schedule, call us at (361) 326-5060.
Why Blackhawk Homes Are Different
Blackhawk sits in the rolling Blackhawk Ranch hills, an inland East Bay enclave where nearly every residence is a custom-built executive home from the 1980s through the 2000s. These aren’t tract houses with standardized duct layouts. Most range from 3,000 to 8,000-plus square feet with multi-zone HVAC systems, and many still run original flex ductwork through unconditioned attics that has now aged past its intended service life.
The local microclimate shapes what we find inside those ducts. Hot, dry summers and mild, wet winters create a cycle where seasonal pollen and wildfire ash get pulled into systems during the long dry months, then winter moisture can push musty odors through attic runs if any condensation has collected. The surrounding open space and dry hillsides mean more airborne particulate than you’d see in a denser suburb.
Then there’s the well-water factor. Most Blackhawk homes draw from private wells, and the mineral-heavy water leaves its mark on indoor air. We’ve opened supply registers to find a fine white residue from hard-water scale, and furnace humidifiers clogged by softener discharge. The rural road network matters too. Unpaved shoulders and long private driveways mean our trucks arrive dusty and need extra setup time for HEPA containment. We build that into every Blackhawk appointment.
Our Main Blackhawk Services
Blackhawk homeowners call us for three core jobs. Each has its own page with full details on what’s involved, what we find locally, and how we price it.
Air Duct Cleaning in Blackhawk
We clean the full supply and return network with a Rotobrush rotary brush system that physically scrubs duct walls, paired with a Nikro negative-air machine to pull dislodged debris out of the house entirely. In Blackhawk, this means handling the extra mineral dust load from well-water environments and the brittle, aging flex duct common in 1980s – 1990s builds. We inspect every run before we start, and we price the full system in writing before touching a tool. Air Duct Cleaning in Blackhawk has the complete breakdown.
Dryer Vent Cleaning in Blackhawk
Long vent runs through multi-story executive homes, combined with the lint-attracting mineral dust in Blackhawk’s air, create serious fire-risk blockages. We use rotary whip tools and high-CFM vacuums to clear the full line from dryer to termination, then verify airflow with a manometer. Most Blackhawk dryer vents need cleaning every 12 – 18 months, not the standard two-year interval. Dryer Vent Cleaning in Blackhawk covers what we charge and what we check.
Duct Sealing in Blackhawk
Aging flex duct in Blackhawk attics often leaks 20 – 30% of conditioned air into unconditioned space. We apply duct sealing mastic and mechanical fasteners at every joint and puncture, then pressure-test the system to confirm the seal holds. For homes with widespread deterioration, we can section-replace failing runs. The work is priced per system, agreed in writing, and covered by our 365-Day Done Right Promise. Duct Sealing in Blackhawk explains when sealing beats replacement.
