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.
Fast, Reliable Air Duct Cleaning Across Kentfield
Air duct cleaning in Kentfield typically costs between $450 and $1,400 for a whole-home system, depending on the number of air handlers and whether ducts run through damp crawl spaces that need camera inspection first. Most Kentfield jobs take four to seven hours, and you get the price in writing before we touch a vent. If you’re calling from the Ross Valley side of town, the phone rings to a live person at (980) 447-2498 any hour of the day.
We know Kentfield homes because we work in them nearly every week. The mid-century ranchers off Sir Francis Drake, the hillside properties up past the College of Marin, the custom builds along Woodland Road. Each one has its own duct layout, and we treat it that way.
Why Linden Air Duct Cleaning Is Kentfield’s Preferred Air Duct Cleaning Company
Homeowners in Kentfield tend to ask the same questions before they book: who exactly is coming, what will it cost, and how do I know you actually did the work. Those are fair questions. Here is how we answer them.
Every technician who enters your home is background-checked, identity-verified, and trained to the Threshold Standard, which has been our operating bar since 2004 as part of the Threshold Group family. Before the visit, you get the tech’s name and photo sent to your phone. At the door, they show a photo ID badge before stepping inside. No exceptions. Marcus Veale, who leads our team, set this protocol up precisely because he knows what it means to let a stranger into your home.
We don’t ask you to trust a brand name. We ask you to verify a person.
Kentfield customers also expect documentation. When a technician spends five hours in your crawl space, you deserve to see what they found and what they removed. That is standard practice on every job, not an add-on.
Air Duct Cleaning Services in Kentfield
Air Duct Cleaning Services in Kentfield means something specific here: source removal under negative pressure, not a brush-and-go. Your ducts run through pier-and-beam crawl spaces and unconditioned attic spans, where fog-driven condensation and fifty-plus inches of annual rainfall keep surfaces damp. That moisture turns ordinary dust into a sticky biofilm that a basic rotary brush won’t lift. Our Air Duct Cleaning team runs truck-mounted and portable HEPA-filtered extraction units to pull the contaminant load out before we finish.
A typical single-system Kentfield home runs $450 to $750. Homes with two or three air handlers run higher, which we’ll cover below.
Full System Cleaning
We clean supply ducts, return ducts, plenums, and the blower compartment as one job. Kentfield homes with original 1950s and 1960s sheet-metal trunk lines need this comprehensive approach, because contamination in one section re-seeds the rest within months if left in place.

Video Inspection
Before we start and after we finish, we run a camera through the main trunk lines. You see the before footage and the after footage on the same screen, with the same angles. If there’s a disconnected joint or a collapsed section hidden in your crawl space, you’ll see that too, and we’ll give you a repair price in writing rather than a surprise at the end.

HVAC Duct Cleaning in Kentfield
HVAC Duct Cleaning in Kentfield is not a luxury when your ductwork predates your heat pump by four decades. Many Kentfield homeowners replace a furnace or add a heat pump but leave the original duct trunks untouched, and the new equipment starts pulling air through decades of accumulated oak pollen, fiberglass insulation fragments, and mold. That is the exact scenario where we get called in.
We clean the full HVAC air path, including the return side, which is where Kentfield’s woodland microclimate deposits the heaviest organic material. A full HVAC duct cleaning for a single system in Kentfield runs $500 to $900. Multiple systems cost more because the labor is per unit and per linear foot of duct, not a flat per-vent rate.
Return Duct Cleaning
Return-air intakes on Kentfield’s east-facing hillside homes back up against Marin Municipal Water District watershed land, under a dense oak and bay laurel canopy. We consistently pull heavy loads of pollen, leaf matter, and spider webs out of these returns. If your return grill looks clean but the duct behind it hasn’t been opened in twenty years, that’s where the problem sits.
Supply Duct Cleaning
Supply ducts carry what the return pulls in. In Kentfield homes with original flex runs through damp crawl spaces, the supply side is where we find mold colonization most often. We use Rotobrush and Nikro equipment with HEPA filtration to clean and capture, not stir up and leave behind.
Trusted Brands We Service in Kentfield
We clean and service duct systems connected to all major HVAC brands, and we stock replacement registers, grilles, and access panels that fit Kentfield’s older ranch-home layouts. Our equipment runs on Rotobrush and Nikro platforms, and we carry air-quality products from Abatement Technologies and Guardsman when a Kentfield home needs filtration help beyond the duct cleaning itself. That matters here because the wildfire smoke seasons of 2017 and 2019 – 2020 pushed fine particulate deep into Bay Area duct systems, and a standard filter swap does not touch what settled inside the trunk lines.
Common Air Duct Cleaning Problems We See in Kentfield Homes
- Mold in pier-and-beam crawl space ducts. Original sheet-metal trunk lines under hillside homes spend most of the year damp from fog and rain. Once mildew takes hold inside the duct, it spreads to the supply side and into living areas on every cycle.
- Oak and bay laurel debris in return-air intakes. Homes bordering watershed land collect an unusual amount of pollen, leaf litter, and fine organic dust. Return ducts on these properties clog faster than flat-valley homes in San Anselmo or Corte Madera.
- Wildfire ash caked inside trunk lines. The 2017 and 2019 – 2020 smoke events that sat over the Ross Valley for days left fine ash deep inside ducts. Rotary brushes alone push this material around; only source removal with HEPA capture actually removes it.
- Unsealed duct joints pulling crawl space air. Older Kentfield homes often have joints that loosened decades ago. If your system is pulling damp, mold-scented crawl space air through those gaps and mixing it with conditioned air, a cleaning alone will not fix it. We seal what we can and show you what needs repair.
Pricing for Air Duct Cleaning in Kentfield, CA
We price per system, not per vent. That is the honest way to quote a Kentfield home, because a three-air-handler hillside property has three distinct duct networks, and cleaning one while leaving two untouched does not solve the air-quality problem. A typical single-system home in Kentfield runs $450 to $750. A two-system home runs $700 to $1,000. A three-system property runs $950 to $1,400. The written quote you receive before any work begins reflects the actual layout of your home, including crawl space access and duct length. Call (980) 447-2498 and we’ll schedule a walkthrough and give you a firm number in writing before you commit to anything.
One flat price per system. Agreed before work starts. That’s the whole deal.

FAQs About Air Duct Cleaning in Kentfield
Homes with original pier-and-beam duct runs in Kentfield should be cleaned every three to four years. The fog-driven moisture cycle and the heavy organic load from the watershed canopy compress that timeline compared to drier East Bay communities. If you smell mustiness when the HVAC runs, or if family members have worsening allergies at home but not away from home, don’t wait for a schedule to tell you. Call (980) 447-2498 and we’ll help you figure out what’s actually going on.
Because a flat rate assumes your house has one system and one duct network, and many Kentfield homes do not. Hillside properties often have separate air handlers for upper and lower levels, plus long trunk runs through unconditioned crawl spaces. If a company quotes you a flat whole-house price without asking how many systems you have, they are pricing a house that is not yours.
Yes, when the mold is inside the ductwork itself, source removal cleaning removes the material that is carrying the odor. But if the source is in the crawl space or a leaking duct joint, cleaning alone will not stop the smell from returning. We camera-inspect before we clean, so you know which situation you are in before any money is spent.
You get before-and-after camera footage of your main trunk lines, a written report of what was found and what was removed, and a written price that was agreed before the work started. If a repair is needed, you get a written guarantee with a free second visit if the repair fails. The 365-Day Done Right Promise covers the work on every job, in writing.
The oak and bay laurel canopy on the east-facing hillside slopes drops pollen and fine organic debris through most of the year, and the return-air intakes pull that material in on every cycle. It’s a microclimate problem that flat-valley homes in Marin don’t share. Regular filter changes help, but the duct behind the filter still needs periodic source removal. Call (980) 447-2498 and we’ll explain what you’re looking at.
What We Found in One 1960s Kentfield Rancher
We were called to a 1960s ranch off Woodland Road where the homeowners had just replaced their furnace but were still smelling mustiness in the living room. Camera inspection of the original sheet-metal trunk line showed heavy mildew growth and a mat of oak pollen clogging the return-air intake. After sealing the system and running a Rotobrush with HEPA filtration under negative pressure, we pulled nearly two gallons of organic debris from the main supply and return ducts. The homeowner said the difference in air feel was immediate. That is a typical Kentfield job for us, not an extreme case.
