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.
Air Duct Cleaning Company in Fairfax, CA
Air duct cleaning in Fairfax costs between $390 and $790 for a typical single-family home, with most finishing right around $540. The number that matters in this town is humidity. Fairfax sits at the mouth of the San Geronimo Valley, where Pacific fog funnels inland and hangs over the town, and that steady moisture works its way into the duct systems of the 1940s to 1970s homes that make up most of Fairfax’s housing stock. We’re Kestrel Air Duct Cleaning, and we approach every Fairfax job with that in mind: the ducts here aren’t just dusty. They’re often damp. Call us at (469) 972-3151 for an honest assessment and a written price before any work begins.
Why Fairfax Homes Are Different
Most of Fairfax was built between the 1940s and 1970s, and the homes reflect that era: craftsman bungalows and wood-frame ranches, many still running their original galvanized sheet-metal ducts with fibrous interior liner. That liner was meant to quiet the system. What nobody planned for was the San Geronimo Valley’s fog, which pushes in from the coast and holds the town in sustained humidity even through the summer months. Condensation forms inside the ductwork, the liner soaks it up, and over years that material becomes a home for mold and bacteria. We see it on nearly every job along Sir Francis Drake Boulevard: sections of flex or galvanized duct that look fine from the vent opening, but once we’re inside, there’s black staining deep in the liner, not just surface dust. Ductwork routed through Fairfax’s unconditioned crawl spaces and attics makes it worse, because those spaces never dry out completely. This is a different cleaning than what a drier town needs. In Fairfax, it’s a mold-remediation job disguised as a dust job, and the homeowners we meet rarely know the liner is even there until we explain it.
Our Main Fairfax Services
Fairfax homeowners call us for two jobs more than anything else: cleaning the air ducts themselves, and clearing dryer vents that the town’s persistent lint and older vent runs make prone to clogging. Tap either one for the full Fairfax page with local pricing and what the job involves.
Air Duct Cleaning in Fairfax
This is the job Fairfax’s older homes need most. We run a Rotobrush rotary brush system through the ductwork to dislodge debris at the duct wall, then pull it out with a Nikro negative-pressure unit so nothing escapes into your living room. In Fairfax specifically, we’re also inspecting the fibrous liner in those 1940s-to-1970s ducts for moisture damage and mold staining. Many homeowners here have never had the system opened since the house was built. Here’s the full breakdown on our Air Duct Cleaning in Fairfax page.

Dryer Vent Cleaning in Fairfax
Fairfax’s older homes often have long, winding dryer vent runs through crawl spaces or along exterior walls, and those runs collect lint faster than short, straight vents in newer construction. Add in the valley’s humidity and that lint becomes a dense, damp plug. We clean the full run from dryer to exterior cap, using a lint trap bypass to get past the dryer itself so the whole line gets cleared, not just the first few feet. Fairfax’s local conditions make this a job worth doing every year, not every three. Details are on our Dryer Vent Cleaning in Fairfax page.

FAQs About Air Duct Cleaning Company in Fairfax
Most Fairfax jobs are scheduled within a few days of the call, and we give you a defined arrival window before we show up. If you call (469) 972-3151, a live person answers and can give you real availability, not an automated message.
No permit is required in Fairfax for air duct or dryer vent cleaning, and no HOA in town restricts the work itself. Some hillside neighborhoods have narrow roads or limited turnarounds worth flagging when you book. Tell us about your street and we’ll plan the vehicle access accordingly.
It can, and that’s the honest truth. Fairfax’s fog-driven humidity means the conditions that cause mold in duct liner can return, which is why we recommend an annual check here, not the “every five years” advice that works in drier towns. We’ll tell you what we saw, show you photos, and give you a straight recommendation.

What Fairfax Customers Say
"My wife's allergies were awful every morning. Had the ducts done and it's made a real difference. Tech was on time and wore booties in the house without me asking."
- Rob Pendergast"Bought an older home and the previous owners had pets everywhere. After Kestrel did the ducts the stale smell was just gone. On time, quick, and they showed me the filter they pulled."
- Preston Ngata"Our dryer was taking two cycles to dry a load. They cleaned the vent and pulled out a frightening amount of lint. Dries in one cycle now and honestly I feel better about the fire risk."
- Marcus Lee
