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 Larkspur, CA
Air duct cleaning in Larkspur runs $450 to $950 for most homes, with the final figure set by the number of systems, duct length, and how much redwood debris and moisture-driven mold the system has collected. Kestrel Air Duct Cleaning handles both air duct cleaning and dryer vent cleaning in Larkspur, backed by a written price before any work begins and a 365-Day Done Right Promise. Dale Whitmore and our team work on Larkspur homes every week, and the thing that separates Larkspur jobs from the rest of Marin is what the coastal redwood canopy puts into the air. Call (469) 972-3151 for a free estimate.
Why Larkspur Homes Are Different
Larkspur sits in a sheltered valley that traps the marine layer rolling in off San Francisco Bay, and that means higher sustained humidity than Corte Madera or San Rafael just a few miles away. Marin’s mild temperatures mean HVAC systems run infrequently, so ducts stay cool and damp for long stretches. Mold spores find that environment welcoming.
Old Town Larkspur adds another layer. The Victorian-era and early-1900s cottages there often have original or retrofit duct systems, some with gravity floor-register configurations that were never designed for modern forced-air flow rates. Decades of particulate settle into those ducts, and a standard cleaning has to account for duct generations that don’t always match even within a single house. Mid-century ranches fill out the rest of the city, so our technicians regularly see mismatched ductwork within individual neighborhoods.
The Baltimore Canyon neighborhood deserves its own mention. Homes there sit directly beneath a coastal redwood canopy, and the fine, waxy redwood needles, spores, and pollen that collect in return-air intakes behave differently than ordinary household dust. Combine that with year-round marine moisture, and you get a duct contamination profile unlike anything in the flatter parts of Marin.
Our Main Larkspur Services
Two jobs account for almost every call we get from Larkspur homeowners: full air duct cleaning and dryer vent cleaning. Each has its own page with pricing, FAQs, and photos, linked below.
Air Duct Cleaning in Larkspur
In Larkspur, air duct cleaning typically means removing years of accumulated dust, pet dander, redwood pollen, and sometimes mold growth from the supply and return sides of the system. We use negative-air extraction, which means a powerful vacuum pulls loosened debris out of the ducts while HEPA filtration keeps it from re-entering the living space. In Baltimore Canyon and other tree-heavy neighborhoods, we often add a wet-extraction step because the pollen and moisture combine into a biofilm that dry brushing alone leaves behind. See Air Duct Cleaning in Larkspur for full pricing and details.
Dryer Vent Cleaning in Larkspur
Dryer vents in Larkspur clog faster than people expect, and the reason is simple: the same damp marine air that complicates duct cleaning also lets lint clump and stick to vent walls instead of blowing through. We run a rotary brush through the full vent run and clear the lint trap bypass area, which is the bend most homeowners never see. In older Larkspur homes, vents often run longer distances to exterior walls, which gives lint more pipe to collect in. Full details are on the Dryer Vent Cleaning in Larkspur page.

Pricing for Air Duct Cleaning Company in Larkspur, CA
Most Larkspur homes fall within the ranges below. Your written quote is confirmed before work begins, and that price does not change at the door.
| Service | Typical Range in Larkspur |
|---|---|
| Air duct cleaning, one system | $450 - $650 |
| Air duct cleaning, two systems | $650 - $950 |
| Mold remediation add-on per duct run | $50 - $110 |
| Dryer vent cleaning | $90 - $180 |
| Rooftop dryer vent run | $150 - $215 |
| Furnace cleaning add-on | $65 - $90 |
| Access panel installation | $65 - $90 |
| Air filter replacement (supplied by Kestrel) | $18 - $40 |
Larkspur prices trend toward the upper end of those ranges when a home sits in Baltimore Canyon or another redwood-heavy pocket, because pollen biofilm and dampness often call for a wet-extraction pass and extra time on mold remediation. Whatever the number, you see it in writing before a single vent is touched.

What Larkspur Customers Say
"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"Set up an appointment for the whole house plus the dryer line. They called the morning of to confirm, showed up in the window, and showed me pictures of the gunk they pulled out. Worth it."
