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 South San Francisco, CA
Most homes in South San Francisco need air duct cleaning for a reason that has little to do with dust: the San Bruno Gap channels wet Pacific fog into the city almost daily, and that moisture ends up inside ductwork. Kestrel Air Duct Cleaning handles the consequences, including mold around registers and failing foil-tape seams on original post-war sheet metal. We give a written price before any work begins, and we back it with the 365-Day Done Right Promise. Call (469) 972-3151 for a free estimate.
Why South San Francisco Homes Are Different
South San Francisco sits directly in the path of the San Bruno Gap, a low break in the Coast Range that funnels dense marine fog and cold, moisture-laden air into the city nearly year-round. Even in summer, when San Bruno and Millbrae get warm afternoons, South San Francisco stays cool and damp. HVAC systems cycle on and off without ever fully drying out, so condensation builds inside supply and return ducts. Homeowners rarely suspect it until an inspection reveals mold growth that standard dust-only cleaning would never address.
The housing stock makes this worse. Sunshine Gardens, the streets around Grand Avenue, and older neighborhoods east of El Camino Real are full of post-WWII tract homes built between the late 1940s and 1960s for shipyard and industrial workers. Many still have their original galvanized or bare sheet-metal ductwork with foil-tape seams that failed decades ago. Those failed seams pull moist crawlspace or wall-cavity air into the duct run, depositing mold spores and debris downstream. Any duct cleaning in South San Francisco that ignores moisture-driven contamination is only doing half the job.
Our Main South San Francisco Services
South San Francisco homeowners call us about two things most often: cleaning the air ducts that move conditioned air through the house, and clearing the dryer vent that carries hot, damp exhaust outside. Each has its own page here with full pricing and local detail.
Air Duct Cleaning in South San Francisco
Air duct cleaning in South San Francisco means removing the dust, pet hair, and mold-affected debris that has built up inside the supply and return lines, especially in the older sheet-metal systems common east of El Camino Real. We use Rotobrush rotary brush systems to dislodge debris at the duct wall, and Nikro negative-pressure units to pull it out without blowing it into your living room. The local fog means we check for condensation damage at every job. Full details are on the Air Duct Cleaning in South San Francisco page.
Dryer Vent Cleaning in South San Francisco
Dryer vent cleaning in South San Francisco deals with lint that packs into the vent run because the humid coastal air keeps it sticky and heavy rather than dry and loose. A clogged dryer vent in a Sunshine Gardens or Grand Avenue home forces the dryer to run longer, and that lint is a fire hazard. We run professional-grade brushes through the full vent length and confirm airflow at the exterior termination. Read the specifics on the Dryer Vent Cleaning in South San Francisco page.

What South San Francisco 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."
