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 typically runs $450 – $850 for a whole-home system, with most jobs completed in a single visit. The persistent marine layer and fog that roll off the Pacific keep duct interiors damp year-round, which means Hollis crews treat mold and mildew as standard concerns here, not afterthoughts. We’re part of the Garrison Partners family, and our San Francisco Bay Area office dispatches background-checked, uniformed technicians to Daly City homes with Rotobrush rotary systems and Nikro negative-air machines. Call (361) 326-5060 for a written estimate before any work starts.
Why Daly City Homes Are Different
Daly City’s cool, foggy summers and near-constant dampness create conditions we rarely see even a few miles inland. The marine layer keeps humidity high and sunshine scarce, which means duct interiors stay moist enough for mold and mildew to establish themselves without the temperature spikes that would dry them out elsewhere.
The housing stock compounds the problem. Many homes are post-WWII tract houses built from the 1940s through the 1960s with original galvanized steel ductwork. That steel corrodes in the salt-laden coastal air, creating pits and rough surfaces where mold spores anchor and colonize. Split-level and stucco-clad homes throughout the city often route ducts through unheated crawlspaces or attics where condensation forms on cold metal during foggy mornings.
In Westlake, we regularly find black mold inside return ducts where decades of fog infiltration have kept the system perpetually damp. These aren’t cosmetic issues. When the furnace or fan kicks on, those spores circulate through living spaces. That’s why Daly City jobs almost always include antimicrobial treatment and moisture assessment alongside mechanical cleaning.
Our Main Daly City Services
Most Daly City homeowners call us for one of three jobs. Each has its own page with full details, pricing, and neighborhood-specific notes.
Air Duct Cleaning in Daly City
We clean the full supply and return network with a Rotobrush rotary brush system that scrubs duct walls while a Nikro negative-air machine pulls loosened debris out of the house entirely. In Daly City, we pay special attention to return plenums and trunk lines where the marine layer has kept surfaces damp for years. Every job includes visual inspection with a duct camera so you see the condition before and after. Air Duct Cleaning in Daly City covers full pricing and what to expect.
Dryer Vent Cleaning in Daly City
Lint accumulation accelerates in humid coastal air, and Daly City’s older homes often have dryer vents routed through walls or crawlspaces that are hard to access and rarely cleaned. We pull the full lint column with a high-velocity air whip and inspect the termination point for proper airflow. Blocked dryer vents are a leading cause of house fires nationwide, and the dampness here makes thorough cleaning essential. Dryer Vent Cleaning in Daly City has the details.
Duct Sealing in Daly City
Corroded galvanized steel and gaps at plenum connections leak conditioned air into crawlspaces and attics, which is especially costly when you’re already fighting humidity. We seal accessible joints with mastic and apply aerosolized duct sealant where appropriate. In Daly City’s fog-prone climate, sealing also reduces the unfiltered outside air that draws moisture and spores into the system. Duct Sealing in Daly City explains the full process and pricing.
