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 Lafayette, CA
Air duct cleaning in Lafayette, CA typically costs $350 – $650 for a whole-home system and takes 3 – 5 hours, with most jobs scheduled within a week. Lafayette’s mix of 1920s storybook cottages and hillside ranch retrofits means we see more complex attic duct runs and rodent intrusion than flatland East Bay cities. We’re Hollis Air Duct Cleaning, and we dispatch crews to Lafayette from our San Francisco Bay Area office. Call us at (361) 326-5060 for a written, upfront estimate.
Why Lafayette Homes Are Different
Lafayette sits in the Contra Costa Valley, where hot, dry summers and seasonal oak pollen push more dust and debris through HVAC systems than coastal Bay Area cities. The surrounding oak canopy drops pollen in spring and leaf debris in fall, while wildfire smoke in recent years has forced homeowners to run filtration harder and longer.
The housing stock tells the bigger story. Lafayette’s core neighborhoods are filled with 1920s-1950s storybook cottages, bungalows, and ranch houses that were never built for central air. Installers retrofitted ductwork through attics and crawlspaces, often using long flex runs that kink, sag, or pull apart at seams. In the older pedestrian-friendly core near downtown, we regularly find hidden attic junctions leaking directly into living spaces after DIY or handyman retrofits. Hillside construction on the north and east slopes adds even longer duct runs and more flexible material, which means more points of failure and more places for rodents to enter. Our technicians clear acorns, leaf debris, and occasional nests from exterior intake screens every autumn.
Our Main Lafayette Services
Most Lafayette homeowners call us for one of these three jobs, each with its own local conditions and pricing.
Air Duct Cleaning in Lafayette
We clean the full supply and return duct network using a Rotobrush rotary brush system or Nikro negative-air machine, depending on access and contamination level. In Lafayette, the challenge is often reaching ductwork buried in tight attic spaces above vintage cottages or routed through crawlspaces that were never meant to hold HVAC. We photograph the interior before and after so you see what came out. Air Duct Cleaning in Lafayette
Dryer Vent Cleaning in Lafayette
Dryer vent cleaning removes lint buildup from the appliance through the exterior termination. Lafayette’s hillside homes often have longer vent runs with multiple elbows, which trap more lint and create higher fire risk. We use rotary brushes and high-velocity air tools to clear the full line, then verify airflow at the exterior cap. Dryer Vent Cleaning in Lafayette
Duct Sealing in Lafayette
Duct sealing closes leaks at joints, seams, and connections using mastic sealant or metal-backed tape. In Lafayette, this matters most in retrofitted systems where flex duct was pulled through attics without proper support, creating sag points that separate over time. Sealing these leaks can drop energy bills and even out room temperatures in homes where one bedroom never gets warm. Duct Sealing in Lafayette
