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 Belmont, CA
Air duct cleaning in Belmont typically costs $350 to $560 for a whole-home system, and most jobs are completed in half a day. Belmont homes present a unique challenge that flatland Peninsula cities rarely face: year-round hillside moisture working its way into crawl-space ductwork. If you’re looking for a duct cleaning company in Belmont that understands damp crawl spaces, fog-fed slopes, and aging flex duct, call us at (980) 447-2498.
Why Belmont Homes Are Different
Belmont’s residential hillsides were built out heavily from the 1950s through the 1970s, and the dominant housing type is the ranch-style or split-level with ductwork routed through a crawl space. That crawl space is the problem. Belmont sits right where the marine layer banks against the Santa Cruz Mountains foothills, so hillside lots stay measurably damper than San Mateo or Redwood City. Groundwater seepage and fog drip work into crawl spaces, and duct joints that were never sealed well let that moist air inside the system.
What we find in Belmont more than almost anywhere else on the Peninsula is fiberglass duct liner inside older sheet-metal trunks that has absorbed decades of ambient moisture. It delaminates, separates from the metal, and starts shedding particles into the air your family breathes. That failure mode is invisible from the outside. A visual check of the registers won’t catch it. You need a camera pushed through the ductwork, and that’s part of every Belmont job we quote.
The older flex ducts in these 1960s-era hillside homes fare no better. Sustained humidity breaks down the plastic outer sleeve, condensation forms on the inside, and the result is mold colonization and particulate buildup inside the duct lining. In Belmont, air duct cleaning is a moisture-damage correction job as much as it is a dust-removal job.
Our Main Belmont Services
Most Belmont homeowners call us first for either whole-system air duct cleaning or dryer vent cleaning. Here’s what each involves in Belmont’s housing stock.
Air Duct Cleaning in Belmont
We run negative-pressure extraction through Riverside-style ranch homes and split-levels built into the Belmont hills, using Rotobrush and Nikro equipment to pull built-up particulate, mold spores, and delaminated liner debris out of the ductwork without filling the living space with dust. For Belmont’s aging flex duct and sheet-metal systems, we camera-inspect first, then clean, then verify with photos. See Air Duct Cleaning in Belmont for full pricing and process details.
Dryer Vent Cleaning in Belmont
Belmont’s hillside laundry rooms are often tucked into tight interior spaces with long vertical or near-horizontal vent runs that exit through roof or exterior wall caps. Lint accumulates faster when vent runs are long and have multiple elbows, which describes a lot of Belmont’s older split-levels. We clear the full run, address any lint trap bypass issues, and verify airflow at the exterior termination. See Dryer Vent Cleaning in Belmont for what’s included.
Air Duct Repair in Belmont
When a Belmont home’s ductwork has disconnected joints, crushed flex runs, or torn liner from years of hillside moisture, cleaning alone won’t fix it. We repair or replace damaged sections, reseal joints to stop crawl-space air from being pulled into the airstream, and bring the system back to proper static pressure. Every repair carries a written guarantee and a free second visit if the repair does not hold. See Air Duct Repair in Belmont for repair-specific pricing.

We service all major brands and keep common replacement components in our Bay Area stock, including Nikro and Rotobrush cleaning accessories and air-quality products from our brands like Honeywell and Aprilaire, so most repairs don’t wait on shipping.

What pushes a Belmont job toward the top of these ranges is access.

What Belmont Customers Say
"Tech arrived with a badge and a printed sheet of what he'd be doing. Ran a camera through the main trunk before and after so I could see the dust difference. Vents smell cleaner already."
- Gina R."Priced by the system, not by the vent, and he told me up front. No pressure to add the sanitizer and I said no without any fuss."
- Faith N."We had construction dust packed into every register after a remodel. They sealed off the returns, used negative pressure, and left the floors cleaner than they found them."
- Paul E.
