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 Danville, CA
Air duct cleaning in Danville typically costs $350 – $650 for a whole-home system and is usually scheduled within a few days, not weeks. The combination of large 1980s – 1990s homes with multiple HVAC zones and recent wildfire smoke events means Danville jobs often require more extensive cleaning than standard suburban work. We dispatch crews from our San Francisco Bay Area office and serve Danville homes with the same equipment commercial operations use: Rotobrush rotary systems, Nikro negative-air machines, and filtration from Honeywell and Aprilaire. Call (361) 326-5060 for a written estimate before any work starts.
Why Danville Homes Are Different
Danville sits in the San Ramon Valley, where the housing stock tells a specific story. Most homes were built during the 1980s and 1990s suburban boom, and they’re large, often 3,000 square feet or more, with multiple HVAC zones serving different wings. That means more ductwork, more returns, and more places for debris to collect over decades.
The climate here creates year-round demand. Summers hit 90°F+ regularly, pushing air conditioning hard and turning duct leakage into a measurable energy drain. But it’s the wildfire seasons that have changed the conversation. After smoke events, we find fine ash deposited in return ducts and plenums in Blackhawk and Diablo homes, material that standard vacuuming won’t touch. The original flex duct in these attics and crawlspaces degrades too, sagging and tearing at connection points where decades of heat cycling have taken their toll.
These aren’t small systems. When a Danville home has three separate air handlers, cleaning takes longer, requires more access points, and demands equipment that can handle the volume without cutting corners.
Our Main Danville Services
Most Danville homeowners call us for one of three jobs, each with its own page and pricing.
Air Duct Cleaning in Danville
We clean the full supply and return network with a rotary brush system and negative-air containment, pulling debris out rather than pushing it deeper. In Danville, this often means addressing ash residue from wildfire smoke events, especially in homes near the hills where infiltration is highest. We photograph the before condition and the after, so you see what came out. Air Duct Cleaning in Danville covers full pricing and what’s included.
Dryer Vent Cleaning in Danville
Dryer vents in Danville’s larger homes run longer distances, sometimes through multiple stories or across attic spaces, and lint accumulates at elbows and termination points where airflow drops. A blocked vent is a fire hazard and wastes energy by extending dry times. We clear the full run and check airflow at the exterior cap. Dryer Vent Cleaning in Danville has the details.
Duct Sealing in Danville
Sealing is the right follow-up when cleaning reveals gaps at plenum connections, disconnected flex runs, or degraded mastic. In Danville’s climate, leaky ducts in a 90°F attic can add 20% to cooling costs. We seal with mastic and mechanical fasteners, then pressure-test to verify the fix. Duct Sealing in Danville explains when sealing makes sense and what it costs.
