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 Oakley, CA
Air duct cleaning in Oakley typically runs $350 – $650 for a whole-home system, with most jobs completed in a single morning or afternoon. We’re Hollis Air Duct Cleaning, and we’ve built our work around the specific conditions that hit Oakley homes harder than most of the Bay Area. The Delta breeze that cools your neighborhood in July is the same wind that carries agricultural dust and pollen straight into your attic ducts. Call us at (361) 326-5060 for a written estimate before any work starts.
Why Oakley Homes Are Different
Oakley sits on the edge of the Sacramento-San Joaquin River Delta, and that geography shapes every duct cleaning job we do here. Most houses went up between the 1990s and 2020s in planned subdivisions like Cypress Grove and Laurel Fields, built with modern flex duct and rigid metal trunk lines. The ductwork isn’t old; it’s clogged with construction debris that never got fully cleared and with seasonal buildup that returns every year.
The Delta breeze picks up fine soil from spring tilling and harvest activity across surrounding farmland. That dust is gritty, it settles deep in flex duct ridges, and standard vacuuming often leaves it behind. We’ve found that proper cleaning in Oakley frequently means pulling attic duct sections to clean and re-seal them, so that agricultural dust doesn’t recycle back into the living space. Mild, wet winters add another layer: poorly sealed systems grow mold where warm attic air meets cool duct surfaces.
Homeowners here aren’t dealing with century-old iron ductwork. They’re dealing with new-ish systems that were never fully cleaned after construction and that sit exposed to conditions most Bay Area suburbs don’t face.
Our Main Oakley Services
Most Oakley homeowners call us for one of three jobs. Each has its own page with full pricing and details.
Air Duct Cleaning in Oakley
We clean the full supply and return system with a Rotobrush rotary brush and negative-air extraction, pulling out the construction debris and agricultural dust that accumulates in Oakley’s flex duct runs. Attic air handlers are common here, so we pay particular attention to the plenum and trunk connections where Delta dust settles thickest. Every job gets a written price before we start and a 365-Day Done Right Promise in writing. Air Duct Cleaning in Oakley
Dryer Vent Cleaning in Oakley
Dryer vent blockages are a genuine fire hazard, and Oakley’s newer subdivisions often have long vent runs through attic space that compound the problem. We clear the full line from dryer to termination, check airflow with a meter, and verify the exterior hood opens fully under pressure. If the vent fails within a year, we come back free under our written promise. Dryer Vent Cleaning in Oakley
Duct Sealing in Oakley
Oakley’s combination of dusty summers and damp winters makes duct sealing particularly valuable. We apply mastic sealant to joints and connections, then test with a pressure fan to verify the seal holds. Sealed ducts stop conditioned air from leaking into the attic and stop Delta dust and winter moisture from being pulled into the system. Duct Sealing in Oakley

What keeps them lower: straightforward single-system ranch layouts with good attic access. Either way, the price is written down before we touch anything, and it doesn’t move at the door.

FAQs About Air Duct Cleaning Company in Oakley
No permit is required for standard residential duct cleaning or dryer vent cleaning in Oakley. Duct sealing that involves modifying or extending the system may need Contra Costa County review; we flag that during the estimate and handle the paperwork if it applies.
We typically book Oakley appointments within three to five business days. Calls are answered by a live person 24 hours a day, and we’ll give you the next available window when you call. Emergency dryer vent blockages get prioritized.
Most Oakley HOAs do not require approval for interior duct cleaning or sealing. If your home has exterior-mounted equipment or if the work requires roof or exterior wall access, check your specific HOA guidelines. We can provide a work description letter if your association asks for one.
