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
Air duct cleaning in South San Francisco runs $450 to $850 for a typical single-family home, with most jobs falling between $550 and $700 for a full system using negative-air or rotary brush methods. We price every job in writing before we start, and every cleaning is backed by our 365-Day Done Right Promise. South San Francisco’s split housing stock and unique SFO-corridor air quality mean duct conditions here differ from neighboring cities, and our crews train specifically for both the pre-war bungalows east of El Camino and the terraced tract homes west of Highway 101. Call us at (361) 326-5060 for a free estimate.
Why South San Francisco Homes Are Different
South San Francisco sits in a narrow coastal plain between San Francisco Bay and the San Bruno Mountain foothills, and that geography shapes every duct system we open. East of El Camino, the 1920s-1950s bungalows often carry original gravity-duct chases or early forced-air retrofits through shallow crawlspaces that stay damp year-round from the marine layer pushing through the Golden Gate gap. West of Highway 101, the terraced 1960s-80s tracts on the Sign Hill slopes run flex duct through unconditioned attics that bake on west-facing exposures, accelerating insulation breakdown and joint separation.
The city’s position directly under SFO’s approach corridor adds a layer you won’t find in Daly City or San Bruno to the same degree. Our technicians regularly pull grey-black fibrous lint from return plenums in houses that otherwise look spotless, a mix of jet-exhaust particulate, harbor-corridor grime, and freeway dust that coats duct walls in a distinctive film within three to five years. The persistent summer fog keeps relative humidity high even when temperatures stay mild, so mold and musty odors show up in ductwork without ever hitting a true heat wave. Come September and October, the dry offshore wind shifts and kicks up pollen and construction dust that loads returns just as homeowners start heating season.
Our Main South San Francisco Services
Most calls we get from South San Francisco homeowners fall into three categories. Each has its own dedicated page with full pricing, process details, and local conditions.
Air Duct Cleaning in South San Francisco
Our Air Duct Cleaning in South San Francisco covers the full supply and return network, from main trunk to each register. In the older flats east of El Camino, we often find decades of layered dust in original metal ducting with no filtration history; in the hillside tracts, we address collapsed flex runs and disconnected boots that leak conditioned air into attics. We use Rotobrush rotary systems for light to moderate buildup and Nikro negative-air machines for heavy contamination or post-renovation jobs. Every cleaning includes before-and-after photos of your own ducts.
Dryer Vent Cleaning in South San Francisco
Our Dryer Vent Cleaning in South San Francisco targets the leading cause of home fires in California. South San Francisco’s older bungalows often have dryer vents routed through 20-plus feet of wall cavity to exterior walls, while hillside homes may have vertical runs through two stories of framing. The same SFO-corridor particulate that loads HVAC returns also clogs dryer lint screens faster here than inland. We clear the full run from appliance to termination, test airflow with a manometer, and flag any damaged venting that needs replacement.
Duct Sealing in South San Francisco
Our Duct Sealing in South San Francisco addresses the leaks that waste 20 to 30 percent of heated and cooled air in most homes. In the terraced west-side tracts, we routinely find flex duct pulled apart at seams by decades of thermal cycling in hot attics. In the older east-side homes, metal duct seams have often lost their original sealant to moisture and vibration. We apply duct sealing mastic and mechanical fasteners to restore system pressure, then verify with a smoke pencil or pressure test. Sealed ducts mean cleaner air, more even temperatures, and lower energy bills.

What you won’t see is a price that changes once we’re inside. We write the full cost down before any work starts, and it does not move at the door.
