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 Francisco, CA
Air duct cleaning in San Francisco runs anywhere from $350 to $750 for a typical two-bedroom flat, and up to $900 or more for a large Victorian with shared duct runs and decades of marine-layer moisture inside. This is not a dusty-desert city. In the Sunset, the Richmond, and anywhere west of Twin Peaks, ducts collect condensation, mold, and collapsed flex liner that you won’t find in Oakland or San Jose. If your vents smell musty or the airflow has gone weak, call Kestrel Air Duct Cleaning at (469) 972-3151 and we’ll give you a written price before any work begins.
Why San Francisco Homes Are Different
San Francisco’s housing stock was mostly built before central forced-air heat existed. The Victorians and Edwardians that line the avenues were framed between 1880 and 1915, and when central heating finally arrived decades later, ductwork got threaded through crawl spaces and floor cavities as an afterthought. That means flex duct runs that are undersized, poorly supported, and often partially collapsed. In the western neighborhoods, the near-daily marine layer keeps humidity high year-round, and condensation forms inside that old duct liner on cool mornings even in July. A duct cleaning job here is often as much a mold-and-mildew remediation as a dust removal.
Multi-unit Edwardian flats add another layer. Shared or cross-connected duct runs between floors are common, which changes the scope and the quote. Our technicians assess for active microbial growth on every San Francisco inspection, because in the Outer Sunset and Outer Richmond it’s routine to pull a section of flex duct and find the interior liner visibly darkened. The homeowner usually had no idea, because the furnace almost never runs long enough to reveal the airflow loss.
Our Main San Francisco Services
San Francisco homeowners call Kestrel for two jobs more than anything else: cleaning the ducts that carry heated air through the house, and clearing the dryer vent that pushes lint outside. Each has its own San Francisco page with full pricing and FAQs.
Air Duct Cleaning in San Francisco
Duct cleaning here means more than brushing out dust. Because fog air condenses inside crawl-space ducts, our crews run a Rotobrush rotary system to dislodge debris stuck to the duct wall, then a Nikro negative-pressure unit to pull it out while Abatement Technologies HEPA filtration keeps loosened particles from re-entering the living space. We inspect every run for moisture damage and collapsed flex before quoting, because a San Francisco duct system with mold needs a different job than one with ten years of dust.

Dryer Vent Cleaning in San Francisco
Dryer vents in San Francisco flats are often long, narrow, and kinked through old framing, which is exactly what traps lint and holds moisture from the fog. When airflow stops, the dryer runs hotter and longer. Our technicians clean the full run from dryer to exterior cap, bypass the lint trap, and confirm airflow at the termination point before we leave. In multi-unit buildings with a shared stack, we also check for cross-connected venting between floors. Dryer Vent Cleaning in San Francisco

What 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."
