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 means working on thousands of nearly identical Henry Doelger tract homes built between 1948 and 1965, most still running original or early-replacement forced-air duct systems now 60-plus years old. Daly City sits hard against the Pacific fog belt, so these aging ducts pull in chronically damp marine air all year, which changes the job compared to inland Bay Area cities just a few miles east. We’ve learned what that fog does to a return plenum in Westlake, and we price the work honestly up front. Call (980) 447-2498 to talk to a real person about your home.
Why Daly City Homes Are Different
The Westlake district is one of the largest intact concentrations of Doelger-built tract homes in the country. That means block after block of stucco-over-wood-frame houses sharing nearly the same floor plan: furnace closet in the same interior-wall spot, return-air grille in the hallway ceiling, and duct runs that were sealed to 1960 standards, not today’s. Most of that ductwork is original galvanized metal or early flex duct, and it has had six or seven decades to collect dust, pet hair, and the fine gritty residue that coastal fog carries in.
Daly City’s marine layer keeps outdoor relative humidity above 80 to 90 percent on most days, and there is no dry-season break. Heating systems cycle even in summer to cut the chill, which pushes that damp air through the ductwork constantly. The return closest to an exterior wall, especially on west and northwest-facing elevations, almost always shows the heaviest staining. We see mold growth in ducts here as a routine finding, not an exception, and it shapes how we quote and how we clean.
Our Main Daly City Services
Most Daly City homeowners call us first about air duct cleaning and dryer vent cleaning, with air duct repair close behind once we show them what the camera saw. Each service has its own Daly City page with local pricing and details.
Air Duct Cleaning in Daly City
We run negative-pressure extraction through every supply and return run, pulling out decades of accumulated debris while the system stays sealed. In Daly City we pay special attention to return plenums and branch runs near exterior walls, where fog-driven moisture has typically left mold staining that inland homes rarely show. We use Rotobrush and Nikro equipment sized for the tight crawl spaces and short attic clearances common in Doelger-era construction. See Air Duct Cleaning in Daly City for full pricing and what to expect.
Dryer Vent Cleaning in Daly City
Daly City laundry rooms are often on the ground floor of a two-story Doelger plan, which means the dryer vent run is longer than typical and turns more corners before it exits. That geometry, combined with the fog belt’s damp air, makes lint stick to duct walls and pack tighter. We clean the full run from dryer to exterior termination and check the lint trap bypass, the gap lint slips past when the trap is full or the mesh is worn. Dryer Vent Cleaning in Daly City covers the process and local pricing.
Air Duct Repair in Daly City
Original Doelger ductwork was sealed with materials never meant to last 60 years in coastal air. Collapsed flex runs, rusted galvanized sections, and return plenums pulling fog-damp air through failed joints are common findings. We repair and reseal what we can, and we tell you plainly when a section is beyond saving. Every repair carries a written guarantee for 365 days, and if it fails we return at no charge. See Air Duct Repair in Daly City for scope and pricing.

What pushes a Daly City quote higher is usually mold remediation on damp return runs and the extra labor of working in tight Doelger-era crawl spaces. You get a written price before any work begins, and it is one flat price per system or job, not a per-vent number that grows once the van is parked.

What Daly City Customers Say
"Thorough job on all eleven vents and the main trunk. Took longer than the three hours they quoted, but he told me early and kept working. Air feels fresher."
- Meredith L."Tech arrived with a badge and a printed sheet of what he'd be doing. Ran a camera through the main trunk before and after so I could see the dust difference. Vents smell cleaner already."
- Gina R."Priced by the system, not by the vent, and he told me up front. No pressure to add the sanitizer and I said no without any fuss."
- Faith N.
