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 Carlos, CA
Air duct cleaning in San Carlos runs between $390 and $690 for most homes, depending on system size and how much moisture has gotten into the ductwork over the years. The western hillside neighborhoods pull in fog that Redwood City largely misses, and that marine moisture settles inside older ducts in ways we rarely see a few miles south. This page explains what San Carlos jobs actually involve, what they cost, and how to reach us at (469) 972-3151.
Why San Carlos Homes Are Different
San Carlos sits just north of Redwood City’s “banana belt,” so the western hills catch coastal fog and marine moisture that pass right over the flats. That fog drifts into attic and crawl-space duct runs, raising humidity levels inside unconditioned spaces even when the rest of the house stays dry. Over time, that steady moisture settles on fiberglass duct liner and inside flex duct, feeding mold and mildew growth that never shows up on a bright, warm afternoon.
The flatlands between El Camino Real and Highway 101 tell a different story. Homes built between roughly 1948 and 1968 often still run their original galvanized sheet-metal ductwork, and in the oldest examples, fiberglass duct board that has deteriorated to the point of shedding particles into the airstream. That means a San Carlos flatland cleaning job is often as much about removing decades of accumulated dust as it is about identifying liner that has passed its useful life. Hillside properties above Alameda de las Pulgas add another layer: irregular duct routing built to accommodate sloped lots, which takes more time to clean thoroughly and costs more than a simple rectangular layout.
Our Main San Carlos Services
Two services account for nearly every call we take from San Carlos homeowners. Each has its own page with local pricing and what the job looks like on-site.
Air Duct Cleaning in San Carlos
Most San Carlos homes we clean have never had their ducts opened, which means the registers, boots, and main trunk lines carry decades of dust, pet dander, and in hillside homes, moisture-related growth. We run a Rotobrush rotary brush through the duct walls to dislodge debris, then a Nikro negative-air unit pulls everything out without blowing it back into your living space. Western hillside jobs above Alameda de las Pulgas frequently reveal condensation staining on flex duct exteriors, which changes how we approach the cleaning. Full details, including what we find in older flatland ranch homes, are on the Air Duct Cleaning in San Carlos page.
Dryer Vent Cleaning in San Carlos
San Carlos laundry rooms in 1950s and 1960s ranch homes often vent through long, narrow runs with multiple elbows, and lint accumulates faster in those than in a straight, modern vent. We clear the entire run from the dryer connection to the exterior termination using a rotary brush, then verify airflow at the exit point so you know it is actually clear. Hillside homes sometimes route vents through crawl spaces where fog-driven humidity turns lint into a dense, matted blockage. The Dryer Vent Cleaning in San Carlos page covers local pricing and how we handle long, awkward vent runs.

In San Carlos, the biggest price driver is moisture.

Whatever the scope, you get a written price before any work starts, and that number does not change when our technician arrives.

FAQs About Air Duct Cleaning Company in San Carlos
Most San Carlos appointments are scheduled within three to five business days of your call. Hillside jobs above Alameda de las Pulgas sometimes take a little longer to schedule because they require more time on-site. Call (469) 972-3151 and we will give you a specific window when you book.
In almost every case, no. Duct and dryer vent cleaning is interior work that does not alter the exterior of the property or require permits. If your San Carlos HOA has specific rules about rooftop access for dryer vents, we can coordinate with the association office, but that is rare.

What San Carlos Customers Say
"Bought an older home and the previous owners had pets everywhere. After Kestrel did the ducts the stale smell was just gone. On time, quick, and they showed me the filter they pulled."
- Preston Ngata"Our dryer was taking two cycles to dry a load. They cleaned the vent and pulled out a frightening amount of lint. Dries in one cycle now and honestly I feel better about the fire risk."
- Marcus Lee"Set up an appointment for the whole house plus the dryer line. They called the morning of to confirm, showed up in the window, and showed me pictures of the gunk they pulled out. Worth it."
