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 somewhere between $390 and $720 for a full-home system, and it’s a different job here than in neighboring Marin cities. The canyon neighborhoods holding Corte Madera Creek’s marine fog create chronically damp attics and crawl spaces. That moisture doesn’t just sit. It feeds the biological growth inside duct systems, which is why we approach Larkspur homes with a moisture-first plan, not a generic dust-and-allergens pitch. You can reach us at (323) 918-4345 for a written quote before anyone touches your vents.
Why Larkspur Homes Are Different
Larkspur sits in a geographic pocket where fog pushes inland along the Corte Madera Creek corridor and then gets trapped by the surrounding hills. Baltimore Canyon and Madrone Canyon get less direct sunlight than nearly anywhere else in Marin. Redwood and bay laurel canopy shades rooftops year-round. What that means for ductwork is simple: the exterior jacket of flex duct stays damp far longer than it would in San Rafael or Novato. We routinely find flex duct insulation that is visibly darkened and musty on the outside, even when the interior surfaces look clean. The material degrades from the outside in. Homeowners with 1990s-era HVAC often assume their system is fine. In Larkspur, that assumption usually costs more down the road.
Downtown Larkspur and the canyon neighborhoods are also packed with Craftsman bungalows and wood-frame cottages built between 1910 and the 1940s. Those homes were retrofitted with forced-air systems decades after construction. Duct runs got shoehorned through wall cavities and crawl spaces never designed for them. Larkspur Landing’s 1980s condominiums have their own issue: original flex duct and duct board now approaching or past its 30-to-40-year service life. Different housing, same root problem. Moisture works on whatever it can reach.
Our Main Larkspur Services
Two jobs make up nearly every call we take in Larkspur: cleaning the duct system, and clearing the dryer vent that pushes moisture out of the laundry room.
Air Duct Cleaning in Larkspur
We connect a professional-grade negative-air collection system to your ductwork and work register by register. In Larkspur, the real diagnostic question is moisture. We check the exterior jacket of flex runs in attic and crawl spaces before we clean, because a musty jacket means the insulation itself has been compromised by shade and damp. Our service includes surface cleaning of registers, the supply and return trunks, and accessible branch lines. The goal is not just removing dust. It’s removing the organic debris from redwood and bay laurel that feeds biological growth. Air Duct Cleaning in Larkspur has the full detail, including what we protect while we work.
Dryer Vent Cleaning in Larkspur
A clogged dryer vent is a genuine fire risk no matter where you live. In Larkspur, the marine air adds another layer: lint gets damp inside the vent and clings to the pipe walls instead of blowing through. That damp buildup compresses, hardens, and restricts airflow faster than in dryer climates. We run professional rotary brushes and high-volume extraction the full length of the vent, from the dryer exhaust to the exterior vent cap. We also check that the termination point hasn’t been buried under fallen bay laurel debris. Dryer Vent Cleaning in Larkspur covers what we do step by step.

What Larkspur Customers Say
"Spotless work. They laid drop cloths everywhere and I was honestly impressed there was zero mess at the end. Showed me the dirt they pulled out so I could see it was worth it."
- Shelby Dunham"New house, old dusty ducts. They were gentle in the house, laid down drop cloths, and double checked every register was sealed back up. Air smells fresh now."
- Scott Hemmings"Friendly, calm crew that clearly cared about the house. Covered their shoes, protected the floors, and double checked they'd closed up every vent cover properly. Would have them back."
