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 Kensington, CA
Air duct cleaning in Kensington, CA typically runs $450 – $850 for a whole-home system, with most jobs completed in a single visit. The town’s heavy oak and maple canopy, combined with post-WWII housing stock and original galvanized steel ductwork, creates a maintenance profile we don’t see in newer Bay Area suburbs. Hollis Air Duct Cleaning dispatches crews from our San Francisco Bay Area office to handle Kensington’s specific conditions, from rust-prone basement ducts to leaf-litter infiltration that standard cleaning often misses. Call (361) 326-5060 for a free estimate.
Why Kensington Homes Are Different
Kensington sits in a pocket of central Connecticut where the housing tells a clear story. Most homes here were built between 1940 and 1980, ranches, capes, and colonials with forced-air systems installed during the post-WWII building boom. Many still run on original galvanized steel ductwork, the kind that rusts internally and traps debris in ways modern flex-duct simply doesn’t.
The heavy oak and maple canopy is the other factor. In autumn, Kensington’s leaf litter gets pulled into outdoor intakes. In spring, pollen loads spike. Standard cleaning that works fine in a newer subdivision often leaves this material behind because it bonds with the rough, rusted interior surfaces of older metal ductwork.
Humidity drives the third problem. Kensington’s summers run damp, and that moisture settles into basement and crawl-space ducts where mold finds a foothold. Winter flips the script, dry forced-air heat circulating dust that has accumulated over months. The result is a year-round cycle, humid growth season, dry distribution season, that demands more than a once-over with a shop vacuum.
Homes near the Town Center carry an additional quirk. Mid-century renovations often left duct joints poorly sealed, and technicians regularly find pressure imbalances that worsen when heating or cooling peaks. You feel it as hot or cold spots, rooms that never quite match the thermostat setting. The duct system itself is the culprit, not the furnace.
Our Main Kensington Services
Most Kensington homeowners who call Hollis need one of three things. Each has its own page with full detail on what we do, what it costs, and what to expect.
Air Duct Cleaning in Kensington
We clean the full supply and return network using a Rotobrush rotary brush system paired with Nikro negative-air machines. In Kensington, the job starts with an inspection for rust scale and leaf-litter accumulation, common in the galvanized steel runs found here. We remove registers, agitate the interior walls mechanically, and extract debris under controlled negative pressure so nothing escapes into your living space. Air Duct Cleaning in Kensington covers full pricing and what happens during the visit.
Dryer Vent Cleaning in Kensington
Dryer vent blockages are a genuine fire hazard, and Kensington’s mature trees compound the problem with lint that mixes with pollen and organic debris. We run a rotary brush through the full vent line to the exterior termination, then verify airflow with a meter. If the vent runs through an original 1960s chase with tight turns, we note structural limitations and discuss routing options. Dryer Vent Cleaning in Kensington has the full breakdown.
Duct Sealing in Kensington
Leaky joints from mid-century renovations are a pattern we see near the Town Center and in surrounding neighborhoods. We apply duct sealing mastic and mechanical fasteners to restore pressure balance, then test static pressure before and after. The goal is even temperatures room-to-room and lower utility bills because conditioned air stops escaping into walls and crawl spaces. Duct Sealing in Kensington explains the process and pricing.
