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
Full-system air duct cleaning in Belmont typically runs $400 – $700 for a standard single-family home, with most jobs completed in one visit. Belmont’s hillside location between the bay and the Santa Cruz Mountains means we see more smoke residue and moisture-related buildup than flatland cities, so our crews arrive with HEPA vacuums and negative-air equipment sized for the job. If you’re ready to schedule, call Hollis Air Duct Cleaning at (361) 326-5060 for a free written estimate.
Why Belmont Homes Are Different
Belmont’s terrain isn’t flat. The city climbs from the bay up into the coastal hills, and that elevation change shapes every HVAC system we touch. Mid-century ranchers on the lower slopes often have galvanized steel ductwork in crawlspaces that have seen sixty-plus years of marine-layer moisture. Move uphill toward the canyon neighborhoods and you’ll find newer construction with flex duct in attics, but those same hills channel wildfire smoke from the Santa Cruz Mountains straight into soffit vents and aging return plenums.
The housing stock tells the story. Most Belmont homes were built between the 1940s and 1970s, with original duct materials that weren’t designed for today’s air quality challenges. Galvanized steel rusts. Flex duct sags and tears. After the 2020 wildfire season, we started finding fine ash coating the interior of flexible ducts even after homeowners had changed their HVAC filters three times. The particles slip past standard filtration and embed in duct walls, where they re-circulate every time the system cycles.
Marine-layer fog rolls in most mornings, especially on the western slopes. That moisture settles into crawlspace ductwork and attic flex runs, promoting mold and mildew that a simple filter change won’t address. Belmont’s narrow hillside streets also mean our Nikro negative-air machines and Rotobrush rotary systems need to be sized for tight access, not just power.
Our Main Belmont Services
Belmont homeowners call us for three jobs most often. Each has its own page with detailed pricing and process.
Air Duct Cleaning in Belmont
We clean the full supply and return system with a Rotobrush rotary brush and Nikro negative-air machine, pulling debris out rather than pushing it deeper. In Belmont, we pay special attention to flexible ducts in hillside homes, where smoke particles from wildfire season bond to the interior walls. Every job gets a written price before we start and before-and-after photos of your own ductwork. Air Duct Cleaning in Belmont covers full pricing and what to expect.
Dryer Vent Cleaning in Belmont
Dryer vents in Belmont’s older ranchers often run through crawlspaces or exterior walls with multiple elbows, creating lint traps that standard brushes can’t reach. We use flexible auger tools and high-velocity air to clear the full run, then verify airflow with a meter. Blocked dryer vents are a leading cause of house fires, and Belmont’s tight hillside lots mean a fire spreads fast. Dryer Vent Cleaning in Belmont has full details.
Duct Sealing in Belmont
Belmont’s original galvanized steel ducts develop leaks at seams and joints, especially in crawlspaces where decades of moisture have corroded the connections. We apply duct sealing mastic and mechanical fasteners to restore system pressure, which cuts energy waste and stops crawlspace air from entering your supply. Homes with flex duct get inspected for tears at sag points. Duct Sealing in Belmont explains when sealing beats replacement.
