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 Fairfax, CA
Air duct cleaning in Fairfax, CA typically runs between $425 and $780 for a full single-system home, with most jobs finishing in 4 to 6 hours. But Fairfax is not a simple dust-and-dander town. The valley catches fog heavier than most of Marin, and that moisture settles into crawl-space ductwork under craftsman bungalows and mid-century ranches, turning what starts as dust into mildew and biofilm. Homeowners here call us about mold staining and musty air more often than plain dust buildup. If you need honest pricing and a crew that understands Fairfax’s older homes, call (980) 447-2498.
Why Fairfax Homes Are Different
Fairfax sits in a fog-collecting pocket of Marin County where marine moisture pushes inland far more intensely than in San Rafael or Novato just a few miles east. Spring and summer mornings bring fog that lingers over the valley well into the afternoon, holding crawl spaces at elevated humidity for long stretches. That matters because most Fairfax homes built between the 1940s and 1970s route their original flex or sheet-metal ductwork through unventilated crawl spaces under the house. The combination of damp air, unsealed duct joints, and deteriorating insulation wrap means moisture and organic debris from the surrounding redwood and oak canopy find their way inside the ducts.
We see the pattern repeatedly on hillside streets where flex duct elbows show visible moisture staining or early mold, even in homes that are otherwise clean and well-kept. Fairfax homeowners also tend to ask pointed questions about sanitizers before booking: many want confirmation that the crew uses fragrance-free, non-aerosolized products, and we respect that. The environmental culture here is strong, and honest answers about low-chemical options are part of earning the work.
Our Main Fairfax Services
Fairfax homeowners call most often about full-system air duct cleaning and dryer vent cleaning, with air duct repair close behind for older systems showing their age.
Air Duct Cleaning in Fairfax
Full-system Air Duct Cleaning in Fairfax starts with negative-pressure extraction, which means the system is placed under vacuum while tools loosen and remove debris from the interior walls of the ducts, preventing dust from escaping into your living space as it is collected. In Fairfax crawl spaces, we often find moisture-compacted debris at the elbow joints that requires extra attention. Before any work begins, the price is written down and agreed to. That includes the sanitization step and any access work in tight crawl spaces.
Dryer Vent Cleaning in Fairfax
Dryer Vent Cleaning in Fairfax clears the full run from the dryer to the exterior termination point. Many Fairfax homes have longer-than-average vent runs through crawl spaces or up through roofs, and lint accumulates faster than homeowners expect. Our techs check for a dryer vent lint trap bypass, which is when lint slips past the internal trap and compacts inside the duct, a common condition in older Fairfax laundry setups. The final check is airflow at the exterior termination, not just a clean look at the inlet.
Air Duct Repair in Fairfax
When ducts under Fairfax homes have separated at the seams or the insulation wrap has degraded, cleaning alone is not enough. Air Duct Repair in Fairfax covers sealing open joints, replacing damaged flex sections, and restoring the insulation so conditioned air stops leaking into the crawl space. Every repair comes with a written guarantee, and if a covered repair fails within 365 days, Linden returns at no charge to make it right. The same flat-price promise applies: the repair price is written before work begins.
Every visit follows the same protocol. The technician’s name and photo are sent to you before the appointment, and you will see a photo ID badge at the door before anyone steps inside. If you are home alone or have young children, that small ritual matters.
