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 Marino, CA
Air duct cleaning in San Marino usually runs between $425 and $780 for a whole-home system, and because most houses here are large pre-war estates with long retrofitted duct runs, the work typically takes a full morning rather than an hour or two. We’re Kestrel Air Duct Cleaning, and we put a written price in your hands before a single vent is touched. If you’re noticing dust settling back on furniture a day after you wipe it down, or musty air when the system kicks on, call (469) 972-3151 and we’ll talk through what’s going on.
Why San Marino Homes Are Different
San Marino doesn’t have the tract-built housing stock you see in most of the San Gabriel Valley. Virtually all of the city’s roughly 4,000 homes are large single-family estates built between 1920 and 1955, in styles that were never designed around forced air: Spanish Colonial Revival, Tudor, and Colonial Revival. Those homes originally had gravity or radiator heating. Forced-air systems came decades later, which means the ductwork was retrofitted through attics and wall cavities never meant to carry it. The result is long, segmented, often convoluted duct runs that collect more debris than a comparably aged house in, say, Alhambra or Pasadena would.
San Marino’s location makes the problem worse. The city sits in the San Gabriel Valley basin with mountains hemming it in to the north, which traps smog and particulate matter. When wildfire smoke rolls down from the foothills – the Bobcat Fire in 2020 is the one most homeowners remember – it doesn’t just stay outside. It gets pulled into return-air intakes and deposited inside ductwork as fine ash. After any significant foothill fire, we see a spike in San Marino calls, and our technicians know to check the return plenum for ash and char odor before diagnosing a “musty smell” complaint. What looks like a mold issue is often wildfire residue, and the fix is different.
There’s another piece to this. Some of these 1920s-to-1950s retrofits still have original flex or sheet-metal ductwork with old joint tape, and occasionally asbestos-wrapped plenums. Those have to be identified before any cleaning work begins, not after a brush has already gone through. That’s a San Marino-specific consideration most companies never mention, and it’s why we walk the attic and mechanical spaces before starting any job here.
Our Main San Marino Services
San Marino homeowners call us most often for two things: the full air duct cleaning in these large estate homes, and dryer vent cleaning for laundry rooms tucked into basements or interior closets with long vertical vent runs.
Air Duct Cleaning in San Marino
Most San Marino homes have 20 to 35 duct runs, and many exceed 40 on the larger 5,000-square-foot estates. That’s a full-day job when it’s done correctly, not a quick pass with a shop vac. We run a Rotobrush rotary agitation system through the supply and return side, pair it with negative-air extraction to pull loosened debris out rather than blowing it into living spaces, and document the before-and-after with photos you can actually see. In these older homes we also check for disconnected duct joints and loose return plenums, which are common after decades of settling and seismic activity. See the full breakdown on our Air Duct Cleaning in San Marino page.
Dryer Vent Cleaning in San Marino
Dryer vents in San Marino often run 15 to 30 feet through walls, crawl spaces, or attics because of where laundry rooms sit in these older floor plans. That’s well beyond the safe length recommended by most dryer manufacturers, which means lint accumulates fast and the risk of a dryer fire climbs with every load. We clean the full vent run and check the exterior termination point for proper airflow. This is a scheduled job, not an emergency call, but it’s one of the highest-value services we do in San Marino given how many vents here are simply too long. Details are on our Dryer Vent Cleaning in San Marino page.

FAQs About Air Duct Cleaning Company in San Marino
San Marino is a small city, and we schedule most appointments within a few business days of the call. The work itself typically takes a half day to a full day depending on the size of the home and the number of duct runs. Call (469) 972-3151 for our current availability.
In most cases, no. Duct cleaning is interior work and doesn’t require a permit from San Marino’s building department. If you’re in an HOA-governed neighborhood, exterior access like roof or yard entry is uncommon for this work, so approval is rarely needed. We’ll flag anything unusual during the walkthrough.
The written price covers the full job as scoped: all duct runs, the return plenum, the air handler compartment, and a post-cleaning airflow check. You get that figure in writing before any work starts, and it doesn’t change unless we find something that genuinely requires a separate scope – in which case we stop and talk to you first.

What San Marino Customers Say
"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."
- Terrence Boyd"My wife's allergies were awful every morning. Had the ducts done and it's made a real difference. Tech was on time and wore booties in the house without me asking."
- Rob Pendergast"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."
