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 San Mateo, CA
Linden Air Duct Cleaning is the air duct cleaning company San Mateo homeowners call when they want to know exactly who is coming to their door and exactly what the job will cost before any work starts. San Mateo’s coastal marine layer and dense stock of 1940s – 1960s Peninsula tract homes create duct conditions you simply don’t see ten miles inland. If your system hasn’t been inspected in years, call (980) 447-2498 for a written, upfront price.
Why San Mateo Homes Are Different
San Mateo sits in a coastal marine zone where summer fog and bay-side humidity keep crawl spaces and attics damp for months at a time. That moisture settles inside ductwork, even in systems that rarely run. Many homes in Baywood, Beresford, and Shoreview were built between the 1940s and 1960s, when forced-air heating was retrofitted through tight, moisture-prone crawl spaces rather than purpose-designed chases. The result is duct runs with inconsistent materials, odd joint angles, and insulation that absorbs bay humidity year-round.
The most striking example is the elevation split across the city. In the low-lying Shoreview neighborhood east of US-101, where 1950s tract homes sit closest to the Bay, ground moisture wicks into crawl spaces constantly. Technicians routinely find flex-duct sections with collapsed inner liners and visible mold at joints. Drive a mile west toward the Highlands, where homes sit on higher, drier ground, and that same failure mode almost never appears. The difference is elevation and moisture, not homeowner neglect. Because San Mateo’s heating and cooling demand is so low, systems go years without extended run cycles that might alert you to degraded air quality. Inspection intervals here tend to be far longer than the national average, which means problems get time to develop quietly.
Our Main San Mateo Services
Most San Mateo homeowners call us for one of two reasons: ductwork that has never been cleaned since a renovation, or a dryer vent that is taking longer to dry clothes than it used to. Here is what each job involves here.
Air Duct Cleaning in San Mateo
We run professional-grade negative-pressure extraction equipment through every accessible supply and return run in your San Mateo home, removing the moisture-laden dust and debris that accumulates in crawl-space-routed systems. In Shoreview and other low-lying neighborhoods, we often find mold at duct joints that homeowners have never seen because the registers look clean from the outside. The equipment we use includes trade-trusted brands like Rotobrush and Nikro, and we document the interior condition before and after so you can see what was actually removed. Read the full breakdown on our Air Duct Cleaning in San Mateo page.
Dryer Vent Cleaning in San Mateo
San Mateo’s older ranch homes often have dryer vents that run long distances through crawl spaces or up through attics, and those runs collect lint differently than a short exterior wall vent. We clear the entire run, not just the accessible section behind the dryer, and check the exterior termination point for proper airflow. A clogged dryer vent in a damp crawl space traps moisture and lint together, which is a recipe for slow drying and a real fire hazard. See our Dryer Vent Cleaning in San Mateo page for pricing and what the job includes.
Air Duct Repair in San Mateo
Older Peninsula homes with piecemeal duct modifications often have failed joints, crushed sections, or insulation that has separated from the duct body. We repair or replace damaged sections using materials matched to your system, then seal joints properly so air reaches the rooms it is supposed to. Every repair we make in San Mateo is covered by a written guarantee, and if a covered repair fails within 365 days, we come back at no charge. Details are on our Air Duct Repair in San Mateo page.

What San Mateo Customers Say
"Thorough job on all eleven vents and the main trunk. Took longer than the three hours they quoted, but he told me early and kept working. Air feels fresher."
- Meredith L."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.
