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.

AfterAir Duct Cleaning Company in Fairfax, CA
Air duct cleaning in Fairfax typically runs $450 – $850 for a standard single-system home, and most jobs are completed in a single afternoon. Fairfax homes sit in a narrow valley with steep, wooded lots, older 1950s – 1970s construction, and a damp microclimate that pushes more debris through ductwork than most of Marin County. If you’re wondering what it costs, how long it takes, or what actually gets cleaned, call us at (737) 727-2314 and we’ll walk you through the exact scope for your home.
Why Fairfax Homes Are Different
Fairfax sits at the foot of the Cascades, where cool marine air meets the valley floor and holds moisture longer than it does in San Rafael or Larkspur. That moisture is the reason we see more fine dust accumulation, mild biological growth, and filter loading in Fairfax homes than in drier parts of the county. The housing stock amplifies it: most homes here were built between the 1950s and late 1970s, with original duct runs that were never designed for the debris load a redwood-adjacent valley produces.
The terrain matters too. Homes along Bolinas Road, Scenic Road, and up toward Deer Park sit on sloped lots with crawlspaces that trap humidity. Ductwork in those crawlspaces runs cooler, condensation forms faster, and the result is sticky dust that a standard vacuum pass won’t fully pull loose. That’s why we run Rotobrush agitation ahead of negative-pressure extraction on nearly every Fairfax job. On flatter streets near downtown and along Sir Francis Drake Boulevard, we see the same aging ductwork but less moisture exposure, which usually means a faster, lighter cleaning. Either way, the age of the system is the dominant factor in Fairfax, not the size of the house.
Our Main Fairfax Services
Fairfax homeowners call us most often for dryer vent work and full air duct cleaning, with HVAC cleaning close behind before the summer heat or the first real cold snap. Here’s what each job actually involves in Fairfax, and the page that covers it in depth.
Dryer Vent Cleaning in Fairfax
Dryer vents in Fairfax run long and awkward, especially in older homes where the laundry room sits on an interior wall and the vent exits through a crawlspace or a second-story soffit. Every extra foot of vent run and every bend adds lint buildup, and in a town where homes sit close together under tree cover, a blocked dryer vent isn’t just a fire risk – it’s a monthly drying-time problem. Our Dryer Vent Cleaning in Fairfax covers full-length brush agitation, HEPA vacuum extraction at the exhaust point, and a before-and-after airflow reading so you can see the difference in writing.
Air Duct Cleaning in Fairfax
Fairfax’s damp crawlspaces and older duct runs mean most systems carry a mix of fine Marin dust, construction debris from decades of remodels, and the kind of sticky particulate that clings to return-side duct walls. Full Air Duct Cleaning in Fairfax starts with a visual inspection of your supply and return registers, then Rotobrush mechanical agitation to break the buildup loose, followed by Nikro HEPA vacuum extraction under negative pressure so the loosened debris goes straight into the collection unit, not back into your living room. You get before-and-after photos of your own registers and plenums, not a stock image.
HVAC Cleaning in Fairfax
When your furnace or air handler has been pulling Fairfax’s damp, dusty air through its coil and blower assembly for a decade or more, the whole system runs less efficiently than it should. HVAC Cleaning in Fairfax includes a full coil cleaning, blower motor and wheel service, condensate pan and drain line flush, and filter housing detail, all done with the same Rotobrush and Nikro equipment we use on ducts. Before the first hot week in September or the first cold spell in December, it’s the single highest-impact service a Fairfax homeowner can schedule.

FAQs About Air Duct Cleaning Company in Fairfax
Most Fairfax jobs are scheduled within 3 to 5 business days, and many neighborhoods can be booked same-week. We’re not a company that promises a 2-hour window and shows up whenever; you get a live trackable arrival time under The Relay Standard, so you know exactly when the uniformed technician will arrive.
Duct cleaning, dryer vent cleaning, and HVAC cleaning do not require a permit in Fairfax, and no homeowner’s association in the area requires approval for interior mechanical maintenance. If you live on a steep lot where roof access is needed for an HVAC unit, that’s between you and your HOA only if the rooftop unit is in a shared or visible area. Call us at (737) 727-2314 if you’re unsure about your property’s specifics.
All of it. We run crews into Deer Park, the hillside homes off Bolinas Road, Cascade Canyon, and every street in between. The only difference is that steep-lot and crawlspace jobs take a bit longer and may run toward the upper end of the posted pricing range because of access time and equipment hauling.
