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 Kentfield, CA
Most Kentfield homes were built without air conditioning, so their duct systems are often heating-only runs that haven’t been cleaned in decades. Combined with the area’s heavy tree canopy, those ducts become repositories for fine redwood and oak pollen rather than the dust-and-mold mix we see in hotter inland markets. We’re Hollis Air Duct Cleaning, part of the Garrison Partners family, and our crews serve Kentfield from our San Francisco Bay Area office with the same equipment commercial jobs demand: Rotobrush rotary systems, Nikro negative-air machines, and filtration from brands like Honeywell and Aprilaire. Call us at (361) 326-5060 for a free estimate.
Why Kentfield Homes Are Different
Kentfield’s housing stock is dominated by mid-century ranch homes and custom hillside houses built from the 1950s through the 1970s. Many still run on original galvanized or early flexible ductwork, and that material deteriorates faster when it’s exposed to the damp coastal air that rolls through Kentfield’s canyon lots.
The climate here shapes the work in specific ways. Mild, damp winters and foggy summers keep ducts free of the heavy condensation problems that plague air-conditioned homes inland, but that same moisture promotes surface mold and mildew in unsealed crawl spaces and attics. When we clean ducts in Kentfield, we’re often focused on microbial remediation rather than the thick dust loads we pull from drier climates.
After a windy October, our technicians regularly find redwood needles and fine oak pollen packed into return registers under eaves. It’s a pattern we don’t see in towns without Kentfield’s density of mature canopy. The terrain matters too: hillside homes with long duct runs and multiple levels require different access strategies than flat-lot ranches in the flats near College Avenue.
Our Main Kentfield Services
These are the three services Kentfield homeowners call us about most often.
Air Duct Cleaning in Kentfield
We clean the full supply and return system with a Rotobrush rotary brush and high-velocity vacuum, or a Nikro negative-air method when the duct layout calls for it. In Kentfield, we pay special attention to microbial growth in unconditioned spaces and the fine pollen that settles in heating-only systems. Every job gets a written price before we start and is covered by our 365-Day Done Right Promise. Air Duct Cleaning in Kentfield
Dryer Vent Cleaning in Kentfield
Dryer vent blockages are a fire hazard, and they’re more common in Kentfield homes where long vent runs through crawl spaces or exterior walls trap lint in the damp air. We clear the full run from appliance to termination, inspect for proper airflow, and note any damage to the vent hood. Pricing is written before work begins. Dryer Vent Cleaning in Kentfield
Duct Sealing in Kentfield
Leaky ducts in Kentfield’s older homes pull musty crawl-space air into living spaces and waste the heating output your furnace already struggles to deliver through deteriorated flexible duct. We seal accessible joints with mastic and mechanical fasteners, then pressure-test to verify the improvement. Duct Sealing in Kentfield
