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 Bruno, CA
Air duct cleaning in San Bruno typically costs between $310 and $610 for a standard single-system home, with most jobs completed in 3 to 5 hours. The hillside lots, older housing stock, and fog-driven humidity from the Pacific make San Bruno ductwork collect dust, pet hair, and moisture-related debris differently than homes over the hill in Millbrae. We’re Cardinal Air Duct Cleaning, and every San Bruno job starts with a written price before any work begins. Call (737) 727-2314 for a same-week estimate.
Why San Bruno Homes Are Different
San Bruno sits in a microclimate pocket where fog rolls over Sneath Lane and Crestmoor Canyon most mornings, then burns off by early afternoon. That daily moisture cycle matters for ductwork: it keeps dust slightly damp, which lets it cling to return-air plenums and around register boots instead of blowing loose. Homes in the Rollingwood and Mills Park neighborhoods, many built between the 1940s and 1970s, often have original galvanized duct runs with more seams and internal ridges than newer flex-duct systems. Those seams trap debris, and the fog cycle effectively glues it in place.
Terrain also changes how jobs run. A lot of San Bruno houses sit on slopes, which means crawlspaces and attics can be tight, and main trunk lines sometimes run at a grade that requires our Rotobrush system to work in shorter passes. We plan for that on the front end, not when the technician is already in the attic. If you’re off Huntington Avenue or near San Bruno Park, access is usually straightforward. Higher up near Crestmoor, we may need to stage equipment at the street and run containment lines up a driveway.
Our Main San Bruno Services
San Bruno homeowners call on us most often for two things: clearing lint-clogged dryer vents and deep-cleaning the supply and return side of a heating system. Here’s how each plays out in San Bruno specifically, with the full detail on each service’s own page.
Dryer Vent Cleaning in San Bruno
Dryer vents in San Bruno run short in single-story ranchers but often stretch 15 to 25 feet in split-levels and hillside additions, which means more bends, more lint collection, and longer drying cycles. The fog season from May through August puts extra moisture into exterior vent hoods, which can turn lint into a matted plug faster than in drier cities. We clean the full run from dryer to exterior termination and leave you with before-and-after photos so you can see the interior was actually cleared. That’s standard on every visit. Full details are on the Dryer Vent Cleaning in San Bruno page.
Air Duct Cleaning in San Bruno
Most San Bruno systems we clean serve forced-air furnaces in homes built before 1980, and many of those supply trunks have accumulated 30-plus years of layered debris. We use a Rotobrush rotary agitation system inside the ductwork, paired with a Nikro HEPA vacuum running negative-pressure extraction, which means loosened debris gets pulled straight into the vacuum rather than pushed back into your living room. The fog-damp dust we mentioned earlier responds well to this method because the brush breaks the surface bond, then the vacuum captures it. See the Air Duct Cleaning in San Bruno page for complete pricing and process detail.
HVAC Cleaning in San Bruno
HVAC cleaning here covers the components beyond the ductwork itself: the evaporator coil, blower motor housing, and condensate pan inside the air handler or furnace cabinet. In San Bruno’s damp microclimate, those parts grow a thin biofilm if the system short-cycles during fog months, and that film holds dust the way duct interiors do. We clean the accessible components with the same HEPA extraction standard, and we include Abatement Technologies containment where attic or crawlspace conditions call for it. Everything we touch is documented with photos. Learn more on the HVAC Cleaning in San Bruno page.

FAQs About Air Duct Cleaning Company in San Bruno
Most San Bruno appointments are scheduled within the same week, often within a few business days. The Relay Standard gives you a live trackable arrival window, so you’ll see exactly when your technician is on the way. Call (737) 727-2314 and we’ll find a slot that fits your week.
No. Air duct cleaning, dryer vent cleaning, and HVAC cleaning are routine maintenance items and do not require city permits or HOA approval anywhere we’re aware of in San Bruno. If your HOA has specific contractor access rules for hillside streets, let us know and we’ll work within them.
That’s common in older Rollingwood and Mills Park homes, and it’s something we handle regularly. Crawlspace access adds time to a job and may affect the final written price, but we’ll identify that before work starts and build it into the quote. There are no surprise charges once we’re on site.
