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 Services in Daly City
Air Duct Cleaning Services in Daly City means one thing to us: removing the damp lint, microbial growth, and rust debris that fog-belt homes accumulate, and showing you the proof with your own photographs. We never quote per-vent pricing. You get one flat price for the entire system before work begins, and that number doesn’t change when the technician arrives.
A standard cleaning includes camera inspection, negative-pressure extraction with a HEPA vacuum, rotary agitation through the supply and return runs, and a walkthrough of the before-and-after photos. Most Daly City homes fall between $395 and $695 for the full system.
Residential and Full System Cleaning
For single-family homes, townhouses, and condos across Daly City, we clean supply ducts, return ducts, registers, and the air handler cabinet. The camera inspection happens before any agitation, so we see exactly what’s inside your return lines before we touch anything.
Video Inspection
In Daly City’s fog belt, video inspection isn’t an upsell. It’s the only way to know whether the dark film in your return duct is ordinary dust or damp microbial growth that needs source removal. We include it on every full system job.

HVAC Duct Cleaning in Daly City
HVAC Duct Cleaning in Daly City tackles the entire heating and cooling loop, from the return grilles to the supply runs to the blower motor cabinet. The marine layer that rolls in off the Pacific keeps interior surfaces damp for months, and that’s where HVAC ducts here differ from inland Bay Area homes. Rusted register faces and microbial growth around the air handler are ordinary findings here, not surprises.
We run a Nikro HEPA vacuum under negative pressure, so loosened debris goes straight into the vacuum instead of back into your living room. Then we run a Rotobrush or Abatement Technologies agitation system through the full supply and return network. Most HVAC duct cleanings in Daly City run $450 – $750, depending on system size and access.
Supply and Return Duct Cleaning
Supply ducts deliver conditioned air; return ducts pull room air back to the blower. Both get coated in Daly City’s damp lint and debris, and both need attention for the system to breathe. Our flat per-system price covers both sides, plus the air handler.
Trusted Brands We Service in Daly City
We clean ducting on every major HVAC brand found in Daly City homes, including Rheem, Carrier, Trane, Lennox, and Goodman systems. We also work with Guardsman filtration and Aprilaire components when homeowners want improved air quality after a cleaning. Our technicians stock common fittings and replacement components for the systems most common in the Broadmoor, Westlake, and Serramonte neighborhoods, which means less waiting when a repair comes up during inspection.
Common Air Duct Cleaning Problems We See in Daly City Homes
- Microbial growth in return ducts from fog-driven humidity. The marine layer keeps duct interiors damp for weeks at a stretch. Without a camera inspection, that growth goes untreated and the musty smell comes back.
- Rusted register faces and flaking debris. Salt air and persistent moisture eat at metal registers in Daly City homes faster than inland. Flakes end up in the air and on your furniture.
- Per-vent pricing that skips the air handler. Registers get wiped while the blower cabinet and deep supply runs stay coated with damp lint. Our flat per-system price covers the whole system, not just the vents you can see.
- No before-and-after photos. In a foggy city where growth is common, visual proof that negative pressure and source removal actually happened matters more, not less. Every Cardinal job includes your own photographs.

FAQs About Air Duct Cleaning in Daly City
Every 3 to 5 years is the honest answer for most Daly City homes, but fog-belt conditions can shorten that. If you smell a musty odor when the system runs, see visible dust on registers, or notice rust flakes on furniture, have a camera inspection done now. Homes with pets, recent remodeling, or smokers typically need cleaning closer to every 3 years. Call (737) 727-2314 and we’ll help you gauge it honestly, without selling you a cleaning you don’t need.
Because the fog belt’s persistent damp keeps duct interiors wet long enough for microbial growth to take hold, and you can’t see that from the register. A camera inspection identifies whether the dark film is ordinary dust or something that needs source removal. In Daly City specifically, skipping the camera step means treating the symptom while the musty cause stays inside your return ducts. We include video inspection on every full system job.
It means the price you agree to before we start is the price on your invoice, and it covers the entire system: supply ducts, return ducts, registers, and the air handler. No per-vent pricing. No add-on charge for doing the blower cabinet. If we open the system and find worse conditions than the camera suggested, the flat price still doesn’t change. Call (737) 727-2314 to get your written quote.
Yes, on every job. We run a Nikro HEPA vacuum under negative pressure, which means the loosened debris goes straight into the vacuum instead of back into your living room. Then we run Rotobrush or Abatement Technologies agitation tools through the full supply and return network. That’s the standard in Daly City, not an upgrade.
Yes, every time. You’ll see camera stills of what the inside of your ducts looked like before we started, and what they look like after source removal and extraction. Visual proof isn’t a courtesy in Daly City, it’s the only way to know the damp growth is actually gone. The photos are delivered with your digital invoice, payable by link from your phone.
