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 Millbrae, CA
Air duct cleaning in Millbrae is a different job than it is almost anywhere else in the Bay Area, and it comes down to location. Homes here sit directly beneath SFO’s flight paths, which means windows stay sealed against noise and exhaust, and the HVAC system becomes the only lung the house has. Add in 1950s and 60s ranch-style ductwork, marine fog, and crawl spaces that trap moisture, and Millbrae duct interiors accumulate far more than ordinary dust. Kestrel Air Duct Cleaning works on these systems every week, with written pricing before any work starts. Call (469) 972-3151 for a free estimate.
Why Millbrae Homes Are Different
SFO’s approach corridors pass right over Millbrae Avenue, the El Camino Real corridor, and the residential blocks that fill the flat between the hills and the Bay. Jet-exhaust ultrafine particles settle into every home, but the response makes it worse: aircraft noise pushes residents to keep windows shut and weatherstripping tight year-round. That means whatever enters the return-air system stays inside and recirculates. Millbrae techs routinely find duct interiors coated with a fine dark residue that tests show contains aviation-related particulates, especially in the neighborhoods closest to the airport perimeter.
The housing stock compounds the issue. Most Millbrae homes were built between the late 1940s and early 1970s, ranch-style and split-level, with original galvanized sheet-metal ducts that were never designed to handle today’s filtration demands. These systems were sized for leaky windows and natural air exchange, not a sealed, tight building envelope. In the crawl spaces under many Millbrae homes, we find aging flex duct that shows tears, sagging, and rodent intrusion points. The dense marine fog that funnels through the San Bruno Gap and lingers over Millbrae most mornings keeps crawl-space humidity stubbornly elevated, which means mold colonization inside older uninsulated runs is a recurring service finding here, not an anomaly.
Our Main Millbrae Services
Two jobs make up nearly everything Millbrae homeowners call us about: the full HVAC duct system and the dryer vent line that runs from the appliance to the exterior.
Air Duct Cleaning in Millbrae
Most Millbrae homes still use the original duct trunks installed in the 1950s and 60s, and those galvanized runs accumulate a specific kind of contamination here: fine aviation particulates bound into household dust and pet dander. Our Air Duct Cleaning in Millbrae service covers the full supply and return pathway using negative-pressure extraction and rotary brush agitation, pulled from a portable HEPA-filtered unit that keeps loosened debris out of the living room. Long flex runs under a raised foundation are checked for tears and disconnected joints before anything is agitated through them.
Dryer Vent Cleaning in Millbrae
Millbrae’s sealed-building habit affects dryer vents too: a lint-clogged line in a tight house means moisture from every load lingers indoors, and the exhaust path from a basement-level laundry up through a crawl space can run 15 feet or more before it reaches daylight. Our Dryer Vent Cleaning in Millbrae service clears the entire run from dryer to exterior cap with brush agitation, checks the cap for proper operation, and documents the before-and-after airflow. This is also a fire-prevention service: restricted airflow from accumulated lint is a leading cause of dryer fires in single-family homes.

What Millbrae Customers Say
"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."
- 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."
