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 Daly City, CA
Air duct cleaning in Daly City costs between $450 and $900 for most homes, depending on the number of vents and the condition of the system. This page is your starting point for understanding what makes duct work different here and what you should expect to pay. Daly City’s fog, humidity, and thousands of Doelger-built tract homes create a specific set of duct problems we see again and again. Both of our main services have their own detailed Daly City pages, linked below. Call (469) 972-3151 when you’re ready for a written quote.
Why Daly City Homes Are Different
Daly City sits directly in the path of Pacific marine air. It is foggier and more humid than nearly any other dense residential city on the Bay Area peninsula. While cities a few miles east get afternoon sun, Daly City’s marine layer often hangs around all day. Ambient relative humidity regularly sits above 80 to 90 percent. That persistent moisture drives condensation inside older duct systems, and condensation feeds mold.
The housing stock compounds the problem. Henry Doelger built tens of thousands of stucco tract homes across Westlake from the late 1940s through the 1950s, most with nearly identical floor plans and nearly identical forced-air heating systems. Because Daly City’s mild climate never demanded central air conditioning, most of these homes run heating-only ductwork that can go years without inspection. Fiberglass duct liner and uninsulated sheet metal absorb moisture from the coastal air. In Westlake, Broadmoor, and St. Francis Heights, we find moisture-fed biological growth in ducts that would stay dry in Colma or South San Francisco. The routing is predictable: under-floor duct chases, crawl spaces, and tight garage-adjacent runs that trap humid air. When we clean one Doelger home, we usually know exactly what the neighbors will find.
Our Main Daly City Services
Daly City homeowners call us most often for two jobs: full air duct cleaning and dryer vent cleaning. Each has its own detailed Daly City page below.
Air Duct Cleaning in Daly City
Full air duct cleaning removes years of accumulated dust, pet dander, and the moisture-fed buildup that Daly City’s humidity encourages. Our technicians use Rotobrush rotary brush systems to dislodge debris at the duct wall, then Nikro negative-pressure units pull it out of the home. In many Westlake and Broadmoor homes, we’re working in tight under-floor chases where moldy fiberglass liner needs real agitation, not a shop vac. See the full breakdown of the process, local pricing, and what to expect at Air Duct Cleaning in Daly City.
Dryer Vent Cleaning in Daly City
Daly City homes built in the Doelger era often vent dryers through long, narrow roof or crawl-space runs. Lint builds, airflow drops, and the humid coastal air makes the problem worse. Our dryer vent cleaning clears the full run from the dryer to the exterior cap, using brushes sized to the pipe and checking airflow before and after. For the complete local breakdown including pricing and signs of a clogged vent, see Dryer Vent Cleaning in Daly City.

What Daly City 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."
