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 Pleasant Hill, CA
Homeowners in Pleasant Hill typically pay $450 – $750 for whole-house air duct cleaning, with most jobs scheduled within a week and completed in a single visit. What makes Pleasant Hill different from nearby Contra Costa cities is the housing stock and the smoke exposure: mid-century ranches and Eichler-inspired homes with original galvanized ducting sit in a valley that traps wildfire particulate from the Diablo Range every fire season. We’re Hollis Air Duct Cleaning, part of the Garrison Partners family, and we dispatch crews to Pleasant Hill from our San Francisco Bay Area office. Call (361) 326-5060 for a free estimate.
Why Pleasant Hill Homes Are Different
Pleasant Hill’s neighborhoods were built in distinct waves, and the ductwork tells the story. The 1950s and 1960s ranch homes near Gregory Lane and Contra Costa Boulevard often still carry galvanized steel ducts sealed with aging asbestos tape. The Eichler-inspired contemporaries in the Gregory Gardens area used flexible foil ducting that degrades faster in hot attic spaces. By the 1970s and 1980s, builders shifted to two-story tracts in neighborhoods like Pleasant Hill Highlands, but many of those systems have never been professionally cleaned in forty-plus years.
The valley geography compounds the problem. Pleasant Hill sits where the coastal marine layer meets Diablo Valley heat, creating inversions that hold dust, pollen, and wildfire smoke at breathing level. After major regional fires, we’ve opened return plenums in homes near Oak Park Boulevard and found fine gray ash coating blower motors. Ridge vents common in the area pull attic air through the system, and if the attic breathed smoke, so did the ducts. This isn’t generic dust removal; it’s sealing systems against infiltration and extracting combustion debris that standard vacuuming won’t touch.
Our Main Pleasant Hill Services
Most Pleasant Hill homeowners call us for one of three jobs. Each has its own page with full details, pricing, and what to expect.
Air Duct Cleaning in Pleasant Hill
We clean the full supply and return network using a Rotobrush rotary brush system for agitation and a Nikro negative-air machine for extraction. In Pleasant Hill, we pay special attention to flex duct connections in older ranches, where tape failure has created leaks that pull attic air into the system. We photograph the before condition inside your main trunk lines, then again after the job. Air Duct Cleaning in Pleasant Hill covers full pricing and what’s included.
Dryer Vent Cleaning in Pleasant Hill
Dryer vent blockages are a leading cause of house fires, and Pleasant Hill’s mature landscaping adds to the risk. Redwood and oak pollen, plus lint accumulation in long vent runs common in two-story tracts, restrict airflow and overheat the dryer. We clean the full run from appliance to termination, test airflow with a calibrated meter, and flag any foil or plastic venting that no longer meets code. Dryer Vent Cleaning in Pleasant Hill has the details.
Duct Sealing in Pleasant Hill
Leaky ducts waste conditioned air and pull in attic contaminants. In Pleasant Hill’s pre-1980 housing, we regularly find disconnected joints and degraded sealing at plenum connections. We seal accessible ductwork with mastic and mechanical fasteners, then pressure-test the system to verify improvement. This is often the right follow-up to cleaning in homes where smoke or dust reappears quickly after service. Duct Sealing in Pleasant Hill explains when sealing makes sense.
