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.

Why Cardinal Air Duct Cleaning Is Fairfax’s Preferred Air Duct Cleaning Company
Fairfax homes aren’t like the tract housing you find in newer parts of Marin. A lot of what we clean here are century-old bungalows and mid-century cabins built into oak and redwood canyons, with return runs that snake through tight crawlspaces. That changes how the job gets done, and it’s why generic duct cleaning checklists fall short. Our crews know these houses because we work in them week after week.
We’re part of the Relay Home Co. family, founded in 2005, and we operate under The Relay Visibility Guarantee. That means every Fairfax booking comes with a live trackable arrival window, before-and-after photos of your actual ducts, and a written price handed to you before a single register comes off. Omar Haddad leads the Cardinal team, and every technician who arrives at your door is background-checked, uniformed, and equipped with professional-grade Rotobrush agitation tools and Nikro HEPA-rated negative-air vacuums. You’ll know your tech’s name before they arrive.
We’ve heard from enough Fairfax homeowners who got burned by low per-vent teaser quotes that we built our entire pricing model around flat per-system rates. One price for the whole house. Agreed in writing. It doesn’t change once the van is in your driveway.
Residential Air Duct Cleaning in Fairfax
Residential Air Duct Cleaning for Fairfax homes means pulling the debris that accumulates inside your supply and return runs: dust, pet hair, the fine grit that seeps in from canyon roads, and in many older Fairfax houses, leaf litter and rodent evidence from crawlspace returns. The process is called source removal, which means we physically agitate the interior walls of the ducts and extract the loosened material with negative-pressure HEPA filtration rather than just blowing it loose with air.
A standard whole-house cleaning for a 3-bedroom Fairfax home runs $450 – $850 depending on the number of returns, crawlspace access, and whether the blower compartment needs attention. We include a camera inspection before we start so you can see what’s actually in there, not what a sales script tells you is in there.
Return Runs and Crawlspaces
In Fairfax, the return side is often where the real problem lives. Long, low-clearance return runs routed through dirt crawlspaces pull in whatever is down there: leaf litter, rodent nesting material, fine silt. A supply-only cleaning never touches that. We clean both sides, and we show you photos of the return interior when we’re done.
Air Handler and Blower Compartment
If the return run is contaminated, the blower motor compartment has been breathing that air every time the furnace cycles. We clean the air handler access area and blower housing as part of the job, because leaving it untouched just re-seeds the system within weeks.
Commercial Air Duct Cleaning in Fairfax
Commercial Air Duct Cleaning for Fairfax businesses covers the same source-removal process scaled to larger systems: retail spaces along Sir Francis Drake Boulevard, offices, restaurants, studios, and community buildings. Commercial jobs in Fairfax typically run $800 – $2,200 depending on square footage, duct length, and the number of rooftop or closet-mounted air handlers involved. We schedule around your hours, including early mornings before you open.
Every commercial job includes the same written price before work starts and before-and-after photo documentation. The Air Duct Cleaning process we use relies on Abatement Technologies containment where needed, especially in occupied buildings where we need to isolate the work area from customer-facing spaces.
Restaurants and Food-Service Spaces
Grease vapor and flour dust settle in duct interiors and become a fire load over time. Fairfax restaurants on Broadway and Bolinas Road need scheduled duct cleaning that addresses both the supply and return sides, plus filter replacement at the unit. We stock common filter sizes on the truck.
Offices and Studios
For offices around downtown Fairfax, indoor air quality complaints usually trace back to return grilles clogged with years of dust and the fine particulate that canyon air pushes through open windows. One visit resets the system, and we provide a digital invoice you can pay by link.
Trusted Brands We Service in Fairfax
We carry filtration products from Aprilaire and Guardsman on our trucks, and our cleaning equipment includes Rotobrush rotary brush systems and Nikro HEPA vacuums. If your Fairfax home has an Aprilaire media filter housing or you’ve been meaning to upgrade to a Guardsman filter, we can usually install it the same day we clean. For older custom-built Fairfax systems with non-standard filter slots, we’ll measure and order what fits, then bring it back on the return visit. No shipment runaround, no guesswork.
Our crew was called to a 1940s bungalow off Bolinas Road where the homeowner noticed dust blowing from the registers whenever the furnace kicked on. The air handler was cycling hot and the return ducts were pulling air through a cracked, debris-filled crawlspace run. We set up negative pressure with HEPA filtration at the unit, used agitation tools and a camera inspection on the trunk and branch lines, and pulled about two gallons of dry oak leaf litter, rodent nesting material, and fine silt from the return before sealing the accessible gaps. The static pressure at the blower motor dropped, the homeowner stopped seeing dust clouds at the registers, and we handed them before-and-after photos of their own duct interiors.
Common Air Duct Cleaning Problems We See in Fairfax Homes
- Crawlspace return contamination: Fairfax’s older housing stock frequently routes returns through dirt crawlspaces, and the negative pressure pulls in leaf litter, rodent debris, and silt. A supply-only cleaning misses this entirely, which is why we always inspect the return side.
- Overheating air handlers: With redwood and oak canopy shading many Fairfax lots, homeowners often close off registers in unused rooms, which increases static pressure and makes blowers work harder. A restricted, dirty evaporator coil or blower wheel compounds the heat load.
- Rodent and vermin debris in ducts: Canyon-adjacent Fairfax homes see more rodent traffic than flatland areas, and duct interiors become travel corridors. We find nesting material and droppings in return runs regularly, which is a health concern for anyone with allergies or asthma.
- Renovation dust from old-house remodels: Fairfax bungalows get remodeled in phases, and drywall dust, sanding residue, and demolition grit get pulled into the ducts during construction. That fine particulate stays airborne and recirculates until the system is source-removed.

FAQs About Air Duct Cleaning in Fairfax
Most Fairfax homes need a full source-removal cleaning every 3 to 5 years, but canyon-adjacent properties with crawlspace returns often need it more often, sometimes every 2 to 3 years. If you’ve had a remodel, a rodent issue, or a recent wildfire smoke season, that timeline shortens. Call (737) 727-2314 and we’ll help you figure out whether you’re due.
We charge one flat price per system. Per-vent pricing is how low-ball quotes turn into inflated invoices once the technician finds a dirty crawlspace return or a contaminated blower compartment. Your written quote covers the whole house, the supply and return sides, and the air handler access.
We set up negative-pressure extraction at the air handler, which means the loosened debris gets pulled into a HEPA-filtered vacuum instead of blown into your living room. Then we agitate the trunk and branch lines with rotary brushes, clean the return runs, inspect with a camera, and seal accessible gaps. Every step is documented with photos.
Yes. Every Fairfax job includes before-and-after photos of your actual duct interiors, not stock images. You’ll see what was in there before we cleaned and what the surfaces look like after. If you want, we’ll show you the debris we pulled out before it goes in the disposal.
No, and we don’t pretend to. Real duct cleaning in Fairfax is a scheduled job that takes four to six hours for a typical home, longer with crawlspace returns. We promise a live trackable arrival window through The Relay Standard, a written price before work begins, and a 365-Day Done Right Promise on every job. Call (737) 727-2314 to schedule a visit that actually fits your calendar.
