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.

AfterFast, Reliable Air Duct Cleaning Across San Rafael
Air duct cleaning in San Rafael typically costs $450 – $900 for a full system on a standard single-family home, and most jobs are completed in 3 – 6 hours. That’s a real range for this market, where housing stock runs from 1940s Eichler-inspired ranches in Terra Linda to newer builds in the Canal and downtown condos. We know San Rafael’s streets, its microclimates, and the way coastal air moves through a house here. If your registers are blowing dust or the furnace smells when it kicks on, call (737) 727-2314 and we’ll give you a straight answer before we ever send a truck.
Why Cardinal Air Duct Cleaning Is San Rafael’s Preferred Air Duct Cleaning Company
We’re the Air Duct Cleaning team San Rafael homeowners call when they want a price they can trust and a crew that shows up on time. Omar Haddad leads our San Rafael work, and he runs every job by one rule: the written price you approve is the price you pay. No per-vent surprises, no add-on charges once the tech is inside. That’s how we’ve built our reputation across Marin, from Gerstle Park to Sun Valley and up toward Lucas Valley.
San Rafael is a phone-first town. People here book services from their phones between meetings or while the kids are at soccer practice in Albert Park. So we built our whole process around that. You call, a live person answers, you get a live trackable arrival window, and you see before-and-after photos of your actual ducts when the job is done. This is the Relay Standard, and it’s non-negotiable on every booking.
Our technicians are background-checked, uniformed, and carry professional-grade Rotobrush and Nikro equipment. You’ll know the tech’s name before they knock. And every job is covered by the 365-Day Done Right Promise: if the work isn’t right within a full year, we return and correct it at no charge. That’s the longest satisfaction window in the trade, and it applies to every single job in San Rafael.
Vent Cleaning in San Rafael
Vent Cleaning in San Rafael is the most common request we get from homeowners in neighborhoods like Bret Harte and Smith Ranch. San Rafael’s coastal fog means dust and fine particulate settle into supply and return vents during the damp months, then bake on when the heater runs in winter. Most standard vent cleaning jobs in San Rafael run $250 – $450, depending on how many supply registers and return grilles the home has.
What a Vent Cleaning Actually Covers
We remove every supply register and return grille, wash them, and run agitation tools through the visible duct runs. Then we set up negative-pressure extraction, which means the loosened debris goes straight into our HEPA-filtered Nikro vacuum rather than back into your living room. In San Rafael homes with older galvanized ductwork, we also check for loose joints that let dust re-enter from unconditioned crawl spaces.
When San Rafael Homeowners Should Call
If you can see dust trails on the wall above a register, or if your furnace smells like lint when it first fires up in November, that’s the signal. San Rafael’s mild climate means systems sit idle for months at a stretch, so dust accumulates in supply runs and then gets pushed out all at once when heating season starts.
Air Duct Repair in San Rafael
Air Duct Repair in San Rafael usually means one of three things: torn flex duct in a crawl space, a disconnected elbow joint above a dropped ceiling in an Eichler-style home in Terra Linda, or a crushed return under a house in Glenwood. Typical repairs run $180 – $400, with the price locked before any work starts. If we find damage during a cleaning, we show you a camera image on the spot and quote the repair separately before touching it.
Duct Sealing and Joint Repair
Older San Rafael homes often have sheet-metal ducts with failing tape or dried-out mastic at the joints. We cut away the old sealant, re-attach the joint with mechanical fasteners, and apply a fresh air-seal that stops conditioned air from leaking into the crawl space or attic. This is one of the best returns on investment we see for Marin County HVAC systems.
Crushed or Disconnected Flex Runs
In crawl-space-heavy neighborhoods like San Rafael’s hillside streets above 101, animals and poorly supported flex duct lead to kinks and disconnects. A disconnected return means your system is pulling in unfiltered crawl-space air. We inspect with camera scopes, show you exactly what we found, and repair it the same visit if parts are on the truck.
Trusted Brands We Service in San Rafael
We service and clean systems from every major brand installed across Marin: Carrier, Lennox, Trane, Rheem, Goodman, and Aprilaire filtration setups. Because we work in San Rafael weekly, we keep common sizes of flex duct, grille boots, and filter media on the truck for quick turnaround. If you have a Guardsman or Aprilaire media cabinet, we can swap in the correct replacement filter during your cleaning to save you the second trip.
Common Air Duct Cleaning Problems We See in San Rafael Homes
- Fog-season dust buildup. San Rafael’s coastal fog settles fine particulate that works its way through registers into supply ducts, then sits there through the warm months. Many homeowners don’t notice until the heater pushes those particles out in a visible plume the first cold morning of November.
- Musty furnace smell at season start. A common San Rafael pattern is a musty or sour smell when the heater first kicks on in late fall. That’s often a dirty blower motor cage plus accumulated dust and moisture in the air handler, not just the ducts themselves.
- Disconnected or kinked flex duct in crawl spaces. Hillside homes and older ranches in San Rafael frequently have flex duct that’s sagged, kinked, or pulled loose from the supply boot, which can silently siphon heated air into the crawl space for years without detection.
- Lint migration into return runs. In homes where the laundry closet backs up to a return chase, dryer lint sometimes gets pulled into the return path. A camera inspection through the register reveals lint accumulation that more basic cleanings miss entirely.
Pricing for Air Duct Cleaning in San Rafael, CA
A full-system air duct cleaning in San Rafael runs $450 – $900 for most single-family homes. That covers all supply runs, return runs, the main trunk, registers, grilles, and the air handler. Condos and townhomes in places like downtown or the Canal typically run $300 – $500 because there are fewer linear feet of ductwork. Larger homes in Lucas Valley or off Point San Pedro Road can push $900 – $1,200. We give you one flat price per system before work starts, never a per-vent price, and we photograph your ducts before and after so you can see exactly what was removed.

FAQs About Air Duct Cleaning in San Rafael
We tell San Rafael homeowners 4 – 7 years, not the 2 – 3 years some national chains push. Because San Rafael sits in a cool coastal fog belt, systems run heat only a few months a year, so mechanical wear is lower and dust settles more slowly than in a Central Valley home with heavy AC use. The best way to know is a camera inspection. If your ducts are clean, we’ll tell you that and save you the money. If they’re dirty, you’ll see the footage yourself before we recommend anything.
One flat price per system. Always. We don’t quote a per-vent price because that’s how bait-and-switch pricing happens: a low per-vent teaser turns into a huge bill once the tech counts every register in your San Rafael home. Before any work starts, you get a written price that covers the full system. Call (737) 727-2314 for an exact quote.
A real cleaning means we cover every supply register and return grille with a containment barrier, hook a HEPA-filtered negative-air machine to the main trunk, and run pneumatic agitation through each run. We then clean the air handler, blower motor, and evaporator coil if accessible. We finish by photographing the inside of your ducts before and after. That’s a NADCA-standard cleaning, and it’s the only kind we do in San Rafael.
Yes, and here’s the San Rafael-specific irony: the fog belt means ducts collect a season’s worth of fine particulate, and then the system sits undisturbed for months. So dust builds in the supply and return runs even when the system isn’t moving air. We often find a camera inspection showing more buildup than the homeowner expected, even in a mild climate. But we also check the air handler and blower motor before recommending a full cleaning, because sometimes a San Rafael system looks dirtier than it actually performs.
Yes. While we’re on site for your duct cleaning, we can clean and inspect your dryer vent as well, including the full run from dryer to exterior. This is a common add-on for San Rafael homes where the laundry room is centrally located and the dryer vent run is long or has multiple elbows. It’s a flat price, quoted before we start, and photographed after. Call us and ask about bundling it with your air duct cleaning.
