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.
Air Duct Cleaning Company in San Mateo, CA
Air duct cleaning in San Mateo runs $425 – $775 for a typical single-family home, with most jobs completed in a half day. We’re Cardinal Air Duct Cleaning, part of the Relay Home Co. family, and we handle duct work, HVAC cleaning, and dryer vent jobs across the Peninsula from our Bay Area dispatch. San Mateo’s mix of 1950s ranchers, hillside properties, and newer townhome developments means every job starts with a real look at your system, not a guess. Call (737) 727-2314 for a written quote before any work begins.
Why San Mateo Homes Are Different
San Mateo sits in a fog belt that does not treat ductwork kindly. Homes in the flats near downtown and the Aragon neighborhood pull in damp marine air most mornings from June through August, and that moisture settles inside return ducts and around evaporator coils. Combine it with the fine dust that drifts off 101 and El Camino Real, and you get a sticky gray film that builds faster than homeowners expect. Hillside properties in Baywood Knolls and Sugarloaf run their systems harder during warm spells, which pulls more air through already-coated filters.
Housing stock adds another layer. Many of the ranch homes built in the 1950s and 60s have never had their ducts opened since construction. Townhomes and newer condos in the downtown corridor often share tight mechanical closets where duct runs bend sharply, making access a job for a professional-grade Rotobrush system rather than a shop-vac. And where HOAs govern exterior vents and shared walls, we already know the access patterns in most San Mateo blocks. That local knowledge means fewer surprises on install day.
Our Main San Mateo Services
Three jobs keep our San Mateo schedule full: dryer vent work that prevents very real fire risks, full air duct cleaning that resets the air you breathe, and HVAC cleaning that keeps the whole system running clean and quiet. Each has its own page below.
Dryer Vent Cleaning in San Mateo
Lint is a combustion risk, not just an inconvenience, and San Mateo’s older laundry rooms often vent through long, narrow runs that hide buildup. Our techs work with Nikro HEPA extraction to pull lint from the entire run, from the dryer collar to the exterior hood. Hillside homes and those with rooftop or second-story vent terminations need care at every bend. We check the hood, the flexible transition hose, and the hidden stretch inside the wall or crawlspace. See Dryer Vent Cleaning in San Mateo for full details and local pricing.

Air Duct Cleaning in San Mateo
A full duct cleaning means getting eyes and tools inside your supply and return runs, and for many San Mateo homes that also means facing decades of dust, pet hair, and the odd construction debris from a past remodel. We use Rotobrush rotary agitation with Nikro HEPA-negative extraction, so debris is captured immediately rather than pushed around. Every job includes a written price first and before-and-after photos of your own ducts. The details live at Air Duct Cleaning in San Mateo.

HVAC Cleaning in San Mateo
Your blower, coils, and drip pan are the heart of the system, and San Mateo’s damp summers encourage a lot of biological growth in exactly those spots. We open the air handler, clean accessible components with professional equipment, replace basic filtration, and confirm the system runs quietly afterward. We’re set up to work with Honeywell, Aprilaire, Abatement Technologies, and Guardsman filtration media. For the full scope in this city, see HVAC Cleaning in San Mateo.

What pushes price upward in San Mateo is access: hillside crawlspaces, rooftop unit housings, runs longer than most in newer developments, and decades of deferred cleaning that doubles labor time. Whatever the number, you get it in writing before a single duct is touched, and it does not change at the door.

FAQs About Air Duct Cleaning Company in San Mateo
We schedule jobs across San Mateo every weekday, and most residents get a window within the same week of calling. We never promise a same-day arrival, but our dispatch team will give you a live, trackable arrival time once the booking is confirmed. Call (737) 727-2314 to check current availability for your neighborhood.
For most single-family homes, no approval is needed for interior duct cleaning. For condos and townhomes, exterior vent terminations and shared mechanical spaces sometimes require a heads-up to the HOA. Our crews know the common patterns in San Mateo complexes and will flag anything that needs board sign-off before we start.
No. Access and system size drive the cost. A single-story Hayward Park rancher typically falls at the lower end of the $425 – $775 range, while a hillside home with a long rooftop vent run and a zoned system runs higher. You will have a written price before any work begins, and that number will not change at your door.
