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.

We know San Rafael’s valley-specific duct problems because we work here every week.
Our Air Duct Cleaning crews serve homes from the flats near downtown to the hillside streets above Gerstle Park and the ranch tracts of Terra Linda. We understand what your system is up against. The phone is answered by a live person, not a voicemail tree. The tech’s name and photo arrive before the visit, and their photo ID badge is shown at the door.
Why Linden Air Duct Cleaning Is San Rafael’s Preferred Air Duct Cleaning Company
San Rafael homeowners keep hiring us for one reason above all: we tell them exactly who is coming, exactly what the job will cost, and exactly what happens if anything falls short. That accountability is the Threshold Standard, and it has been the foundation of our work since 2004 as part of the Threshold Group family. Every technician is background-checked, identity-verified, and arrives in a clean, marked uniform.
We are not a call center that subcontracts to whoever is closest. Our San Rafael work is handled by technicians who know the difference between a Gerstle Park Victorian’s retrofitted supply runs and a Terra Linda ranch’s original 1960s galvanized trunk lines. Marcus Veale leads our team, and the standard he enforces is simple: the price in writing before any work begins, and a 365-Day Done Right Promise on every job. If the work is not right, we make it right. In writing. Every time.
Residential Air Duct Cleaning in San Rafael
Residential Air Duct Cleaning in San Rafael is a source-removal process, not a surface wipe-down. We use negative-pressure extraction to pull settled dust, pet dander, insulation fibers, and wildfire ash out of your supply and return ducts without blowing it back into your living space. A typical single-family home in San Rafael runs $425 – $690 for a complete system clean, and the price is written down before we start.
Supply Duct Cleaning
Supply ducts deliver conditioned air to each room. In San Rafael’s older homes, these runs often pass through unconditioned attic space where heat and fog cycles have loosened connections and pulled in debris. We clean the full interior surface of each supply run using HEPA-filtered negative pressure and mechanical agitation.
Return Duct Cleaning
Return ducts pull air back toward the blower. In Terra Linda ranch homes with partially crushed or disconnected runs, returns often draw attic air directly into the system. We inspect and clean every return path, and flag disconnections that need repair before the next smoke or fog season loads your ducts again.
Commercial Air Duct Cleaning in San Rafael
Commercial Air Duct Cleaning in San Rafael covers offices, retail spaces, medical suites, and multi-family buildings throughout the city. We understand that a commercial job means coordinating around occupant schedules and minimizing downtime. Commercial system pricing in San Rafael typically runs $1,100 – $2,800 depending on square footage, number of rooftop units, and duct complexity. Every commercial job receives the same written price before work begins and the same 365-Day Done Right Promise.
Full System Cleaning
A full-system commercial clean includes supply and return trunks, branch runs, air handler interiors, and blower compartments. We use Rotobrush and Nikro equipment sized for larger commercial duct networks, with HEPA filtration throughout the job. Your tenants or employees keep working while we clean.
Video Inspection
Before and after every San Rafael commercial job, we run a camera through the system. You see what was in your ducts and what was removed. That record is yours, and it is the same proof we provide on residential jobs.
Trusted Brands We Service in San Rafael
Our technicians work with professional-grade equipment from Rotobrush and Nikro, and we recommend air-quality products from Honeywell, Aprilaire, Abatement Technologies, and Guardsman where they solve a real problem. If your San Rafael home needs a better media filter or an air-quality upgrade following a smoke season, we can supply and install the right component. Because we stock common parts locally, we can often complete a full duct clean and a filter upgrade in the same visit, with one written price covering both.
Common Air Duct Cleaning Problems We See in San Rafael Homes
- Marine fog and wildfire smoke compounding in ducts: San Rafael’s valley bowl traps both, so ducts here hold damp marine particulate and fine ash in the same system. That layered contamination is harder to remove and reaccumulates faster than in drier neighboring cities.
- Disconnected original duct runs in Terra Linda ranch homes: We regularly find 1960s galvanized trunk lines that have separated at joints in unconditioned attics. The system pulls attic air, not filtered air, into living spaces.
- Mold and dust-mite growth from condensation cycling: The swing between winter fog and 95°F+ summer heat inland creates condensation inside attic ducts. That moisture feeds microbial growth on settled dust and ash.
- Blower compartments recontaminating clean ducts: If the blower motor and housing are not cleaned during a duct job, fine particulate from San Rafael’s fog-and-smoke cycles blows back into supply runs within weeks. We clean the blower compartment as part of every full-system job.

FAQs About Air Duct Cleaning in San Rafael
Because San Rafael’s valley geography traps two contaminant loads that those other areas rarely see at the same concentration. Winter marine fog pushes damp particulate into duct systems, and North Bay wildfire seasons from 2017, 2019, and 2020 deposited fine ash and PM2.5 that settled into supply and return runs. Coastal San Francisco gets fog without the same wildfire ash load, and the South Bay gets heat without the same trapped moisture. San Rafael gets both, and the condensation cycles between damp winter air and 95°F+ summer heat in inland neighborhoods like Terra Linda turn that combined debris into a microbial growth medium. A home here genuinely benefits from cleaning every three to five years, and more often if you live near open space chaparral. Call (980) 447-2498 and we will tell you honestly whether your system needs work now.
No. Fogging or misting wets whatever is already in your ducts, including settled ash and dust, and in San Rafael’s damp winter air that moisture can feed mold growth rather than stop it. A sanitizer applied over contamination is not source removal. A genuine clean removes the settled debris first using negative pressure, HEPA filtration, and mechanical agitation; only then, if the system still shows microbial growth, is a registered antimicrobial applied according to label directions. Be wary of any company that leads with fogging as the headline service. Call (980) 447-2498 and ask us to walk you through what a real NADCA-standard clean includes before you book anything.
Watch for musty odor when the heat cycles on, visible dust blowing from registers, and rooms that never quite reach the temperature the thermostat says they should. Original Terra Linda ductwork is frequently galvanized trunk line run through unconditioned attic space. Heat expansion over 60 years separates joints, and partial crushing from decades of attic traffic disconnects runs entirely. When that happens, the system pulls attic air straight into the supply side. A camera inspection shows exactly what is happening before you pay for any cleaning. We do that inspection as part of every estimate in Terra Linda. Call (980) 447-2498 for a free estimate with camera inspection.
You look for three signals: a persistent musty or earthy smell that gets stronger when the system runs, visible dark spotting around register openings or inside accessible duct sections, and family members experiencing allergy-like symptoms that improve when they leave the house. San Rafael’s winter fog and inland summer heat create condensation cycles inside attic ducts, and condensation on settled dust and wildfire ash is exactly what mold needs to grow. A camera inspection can confirm whether the staining is active growth or just old discoloration. We do not sell you a mold treatment unless the inspection shows a real problem. Call (980) 447-2498 and we will show you the footage.
In most San Rafael homes, yes, and the reason is simple: both systems share the same lint and particulate environment. Lint buildup in dryer vents is a fire hazard, and blocked vents force your dryer to work harder and run synthetics through repeated heating cycles. If we are already at your San Rafael home with negative-pressure equipment, adding dryer vent cleaning typically costs $85 – $150 depending on vent length and access. Both jobs are done in one visit, with one written price. Call (980) 447-2498 for a combined quote.
