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 Kentfield, CA
Air duct cleaning in Kentfield is a job shaped by the Ross Valley’s fog, rain, and hillside lots. Most homes here sit on pier-and-beam crawl spaces where damp air moves through aging ducts year-round, and that changes what we find inside them. Our crews work with the specific reality of 1950s through 1970s Marin construction: original flex and sheet-metal runs, heavy woodland debris on hillside returns, and moisture-driven mold growth that flat-valley homes rarely see. If you’re researching air duct cleaning in Kentfield and want to talk through what your home actually needs, call us at (980) 447-2498.
Why Kentfield Homes Are Different
Kentfield sits at the base of the Marin hills where coastal fog pours in every morning before afternoon sun burns it off. That daily humidity swing does something specific inside ductwork: condensation forms on poorly insulated runs, and over time that moisture invites biological growth you would not see in drier parts of Marin. The watershed land along the east-facing slopes adds another layer – homes tucked under oak and bay laurel canopy collect pollen, leaf litter, and fine spider webbing in return-air intakes at a rate that surprises homeowners.
Most of Kentfield’s housing stock dates to the post-war building boom: ranch homes and custom 1950s and 1960s builds where the original ductwork is often still in service. We regularly walk into beautifully renovated homes with modern HVAC condensers attached to trunk lines installed when Eisenhower was president. The renovation budget went to the visible parts of the house; the ducts stayed untouched. Add in wildfire smoke seasons that push fine ash through the valley, and the inside of a typical Kentfield duct system is a layered record of everything the Ross Valley has thrown at it.
That is why generic duct cleaning checklists do not fit here. A Kentfield job means checking for moisture-related growth in crawl-space runs, pulling woodland debris from returns on hillside lots, and understanding that a mid-century duct layout does not clean the same way as a 2005 build.
Our Main Kentfield Services
The two services Kentfield homeowners call us about most are full-system air duct cleaning and dryer vent cleaning, with duct repair close behind. Each has its own page here because each job has different requirements in this climate.
Air Duct Cleaning in Kentfield
Our Air Duct Cleaning in Kentfield service uses negative-pressure extraction to pull accumulated debris out of your ductwork without spreading it through the house. In Kentfield, that debris is typically a mix of construction dust from renovations, wildfire ash, pet dander, and – in many crawl-space systems – biological growth from years of Ross Valley humidity. We walk the system with you before work starts, show you what we are seeing, and take photos so you can compare what the inside of the ducts looked like before and after.
Dryer Vent Cleaning in Kentfield
Dryer Vent Cleaning in Kentfield matters more here than homeowners realize. Lint accumulation in a dryer vent is a fire hazard, and Kentfield’s hillside homes often have long vent runs from laundry rooms buried deep in the house out to exterior walls or roof lines. Long runs mean more surface area for lint to catch, especially when moisture from the fog slows drying time. We pull the lint trap bypass, clear the entire run with professional equipment, and verify airflow at the exterior vent before we leave.
Air Duct Repair in Kentfield
When ducts have failed – disconnected joints, crushed runs under a crawl space, rust-through in sheet metal – cleaning alone cannot fix the system. Our Air Duct Repair in Kentfield service addresses real damage, and every repair we make carries a written 365-day guarantee. If a covered repair does not hold, we return and make it right at no charge. In Kentfield’s damp crawl spaces, we commonly find separated flex duct joints and sagging trunk lines that pull apart at connections, which is where most of the air you are paying to heat or cool escapes.

Brands We Service in Kentfield
Because Kentfield’s housing stock spans seventy years of construction, we service every brand and configuration we encounter in the field: original sheet-metal trunk lines, flex duct retrofits from the 1980s and 1990s, and modern systems tied to updated condensers. Our our brands page lists the equipment and air-quality products we work with, including Abatement Technologies, Guardsman, Rotobrush, and Nikro. If your system has a nameplate we have seen it before, and if we have not, we will figure it out on site rather than reschedule the job.

The quote you receive is the price you pay – we put it in writing before any work begins, and there is no per-vent add-on pricing after the fact.

FAQs About Air Duct Cleaning Company in Kentfield
Most Kentfield air duct cleaning and dryer vent cleaning appointments are scheduled within one to three business days. Repair work depends on what we find and what parts are needed, but we will tell you on the first call what the timeline looks like and hold to it.
Most Kentfield HOAs do not restrict interior duct cleaning or repair. Some hillside and watershed-adjacent developments have rules about roof penetrations or exterior vent changes, and we will flag that early if it applies to your job. Call us at (980) 447-2498 and we will help you figure out what applies.
Most Kentfield homes built before 1980 have at least part of their duct system running through a pier-and-beam crawl space, and we are used to that. Tight clearances and hillside terrain add time but rarely make a job impossible. Your quote accounts for access conditions before work starts, so there are no surprises on the bill.
