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.
Air Duct Cleaning Company in Kentfield, CA
Air duct cleaning in Kentfield, CA typically costs $450 – $850 for a standard whole-home system, and most jobs are finished in a single visit. What makes Kentfield work a little different from nearby Marin towns comes down to three things: older custom homes built between the 1950s and 1980s, mature landscaping that puts real pollen and fine debris into return air, and a microclimate where fog meets dry inland heat. We’re Cardinal Air Duct Cleaning, part of the Relay Home Co. family founded in 2005, and every Kentfield job includes a written price before any work starts. Call (737) 727-2314 and a live person answers.
Why Kentfield Homes Are Different
Kentfield sits in a narrow band of Ross Valley where the marine layer rolls over the hills every evening and burns off by mid-morning. That daily temperature swing matters for ducts: condensation forms inside sheet metal runs overnight, and anything already sitting in the ductwork – dust, pet dander, construction debris – turns into a paste that clings instead of blowing through. Homes along Sir Francis Drake Boulevard and up into the Kent Woodlands neighborhoods tend to run larger, with long horizontal duct runs through crawl spaces and over garages. Those extended runs lose more conditioned air to leakage, which means the system pulls harder and draws more unfiltered attic or crawl space air through every gap. We see this pattern constantly: a 1970s Kentfield home with original flex duct and a 3,000-square-foot footprint moves far more debris through its returns than a newer Corte Madera townhouse ever would.
Housing stock here tilts toward custom builds from the mid-century boom, and many have gone through phased remodels. That means mixed duct materials – original sheet metal in one wing, flex duct added during a 1990s addition somewhere else. Each material cleans differently, and a one-size-fits-all truck-mounted shop vac approach leaves the flex runs untouched. We run Rotobrush rotary brush systems through the hard pipe and use negative-pressure extraction – that means loosened debris goes straight into our Nikro HEPA vacuum, not back into your living room – so both materials get the right treatment in the same visit.
Our Main Kentfield Services
Kentfield homeowners call us most often about two things: dryer vents that have never been cleared and full HVAC systems that have picked up decades of Ross Valley dust. Here’s what each job looks like in Kentfield.
Dryer Vent Cleaning in Kentfield
Dryer vent runs in Kentfield homes frequently extend 15 to 25 feet or more, often through a crawl space or up through an interior wall to a roof cap. That length, plus the lint that Marin’s hard water leaves behind from washed fabrics, creates a real fire risk when it accumulates. We clean the full run with rotating brush systems and confirm proper airflow at the exterior termination point. If you’re not sure when your vent was last cleared, start with a Dryer Vent Cleaning in Kentfield visit and we’ll show you before-and-after photos of your own vent line.

Air Duct Cleaning in Kentfield
Whole-system air duct cleaning in Kentfield means opening the supply and return plenums, brushing every accessible run, and pulling the loosened debris out under negative pressure with a Nikro HEPA vacuum. In older Kentfield homes with original sheet metal and newer flex additions, we inspect each section for leaks, damaged insulation, or collapsed runs before we start. Loose duct connections in a Kentfield crawl space pull in damp, particulate-heavy air. The full breakdown of what we check and how we price it is on our Air Duct Cleaning in Kentfield page.

HVAC Cleaning in Kentfield
HVAC cleaning in Kentfield goes further than the ducts themselves: we clean the evaporator coil, blower motor housing, condensate pan, and the supply registers throughout the house. A coated coil in a Kentfield home’s furnace closet or attic air handler cuts airflow and drives up cooling costs all summer. We use Abatement Technologies containment units to capture anything brushed loose during the job. For coil specifics, filters, and the written guarantee that covers every repair, see HVAC Cleaning in Kentfield.
