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, CA typically costs $350 – $575 for a single-system home, and most Cardinal jobs are completed in a single afternoon. Danville’s mix of 1970s – 1990s ranch homes and newer custom builds means duct systems vary widely, from original sheet metal to flexible duct runs added during remodels. That variety is exactly why we give a written price before any work starts. If your vents have gone years without attention, call (737) 727-2314 and we’ll tell you what you’re looking at.
Why Danville Homes Are Different
Danville sits in the San Ramon Valley, where summer temperatures regularly climb into the 90s and winter mornings dip into the 30s. That swing puts real strain on ductwork. Homes along Diablo Road and Greenbrook Drive, many built before 1990, often have original galvanized ducts with failing seams and decades of dust packed into returns. Meanwhile, newer developments near Blackhawk and Tassajara Ranch tend to have tighter building envelopes, meaning whatever is in the ducts recirculates more aggressively.
We also see a lot of homes that had rooms added or converted during the last twenty years. In those cases, the original return-air sizing was never recalculated, so one return struggles to pull from the entire house. The result is uneven temperatures and dust settling faster in some rooms than others. Older Danville homes near the Iron Horse Trail frequently run their systems harder in summer, which forces more air through dirty coils and filters faster. That combination matters more than square footage when it comes to how dirty a system gets.
Our Main Danville Services
Most Danville homeowners call us about two things: dryer vent cleaning, where a clogged vent becomes a fire risk, and full air duct cleaning, where years of dust, pet dander, and construction debris have built up inside the system. Below are the three services we handle across Danville, each on its own page with pricing and local detail.
Dryer Vent Cleaning in Danville
Danville homes with second-floor laundry rooms often have dryer vents running 15 to 25 feet through walls and across attic spaces before they exit the roof. Every bend in that run collects lint. We snake a rotary brush through the full length, then pull everything out with a negative-pressure vacuum, meaning the lint moves out of the exit point rather than blowing back into your laundry room. If your clothes are taking two cycles to dry, Dryer Vent Cleaning in Danville is worth a look before the vent gets dangerously restricted.
Air Duct Cleaning in Danville
Older Danville systems often hold more than dust. We find drywall dust from remodels, pet hair, and in homes near open space, a fine clay-like particulate that drifts in from the surrounding hills. Our process uses a Rotobrush rotary system to knock debris loose, paired with Nikro HEPA-filtered extraction so the particulate is captured at the source and not released through your registers. For the full breakdown of how we handle single-zone and multi-zone Danville homes, see Air Duct Cleaning in Danville.
HVAC Cleaning in Danville
The San Ramon Valley’s hot dry summers force AC systems to run for months at a stretch. Condensate pans, blower wheels, and coils all collect a film of dust that reduces airflow and makes the system work harder. We clean the full air path from return to supply, including the blower assembly and evaporator coil where access allows. If your system runs constantly in August or you notice a musty smell when the AC cycles on, read more at HVAC Cleaning in Danville.
