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.

AfterFast, Reliable Air Duct Cleaning Across San Bruno
Air duct cleaning in San Bruno typically costs $525-$875 for a full single-family system, depending on the number of returns and duct runs we’re working with. That’s the written price you’ll get before any tool touches a panel. We clean residential and commercial duct systems across San Bruno, from the Crestmoor hills down to the flats near Tanforan, and we’ve learned that the homes here carry a distinct particulate load you won’t find in Burlingame or San Mateo. If your registers are pushing out air that smells faintly of jet fuel or old damp, call (806) 606-6902 and we’ll bring a camera.
Why CleanRun Air Duct Cleaning Is San Bruno’s Preferred Air Duct Cleaning Company
We’re independently owned and operated under the Haven Standard, and we’ve been at this since 2013. Every San Bruno job gets a written price before work starts (Haven Standard Clause 1), a background-checked crew in uniform, and a documented photo record of every duct run we touch. That last part matters here more than almost anywhere on the Peninsula, because what we photograph in San Bruno ducts is not the usual household dust. It’s a dark, fine-grained film that other cities don’t see at the same rate.
Our Air Duct Cleaning team works San Bruno regularly enough to know the difference between a 1950s sheet-metal return and a Crestmoor rebuild with newer flex duct. That’s not trivia. It changes how we quote and how we clean. Tomas Reyes, who leads our crews, insists on a camera pass before any agitation tool goes in. On older systems, that’s the difference between a clean that improves airflow and an aggressive run that tears a deteriorated flex connection.
Our Air Duct Cleaning Services in San Bruno
Residential Duct Cleaning
Most San Bruno homes we service are post-WWII construction from the late 1940s through the 1960s. Many still run on original sheet-metal ductwork. Our residential clean covers the full supply and return sides, registers, and the plenum, using negative-pressure extraction with HEPA-filtered air so what we pull out doesn’t get pushed back into living spaces. We photograph every run before and after and include that record in your job file.
Commercial Duct Cleaning
Offices and retail spaces near El Camino Real and the Tanforan area deal with the same SFO-adjacent particulate load as homes, but with longer runtimes and more foot traffic. We schedule commercial jobs during off hours and provide the same documented photo record and written scope of work that our residential customers get. No fogging upsells. No per-vent pricing games. One written price before work starts.
Supply Duct Cleaning
The supply side carries conditioned air out to your rooms. In San Bruno, supply ducts on the north and west sides of the city foul faster because they draw in return air that’s been circulating through a home pulling in outside air through windows, door gaps, and the HVAC intake. That outside air carries the ultrafine particulates from SFO departure corridors. A supply-only clean leaves the return side untouched, which means you’re pulling dirty air back through the system the moment the blower kicks on.
Return Duct Cleaning
Return ducts are where we find the heaviest buildup in San Bruno. The return side is under negative pressure, so it acts like a vacuum pulling in whatever’s floating in the house. In older tract homes, that often includes decades of dust, pet dander, and a persistent oily residue that we trace back to jet-exhaust infiltration. We recommend cleaning both sides together. A half-cleaned system is a system that will recontaminate itself.
Full System Cleaning
A full system clean means supply ducts, return ducts, registers, the plenum, and the air handler cabinet. For the kinds of contamination we see in San Bruno, this is the only approach that makes sense. We run the blower during the process so that what we dislodge gets captured by the negative-pressure collector, not pushed into your living room.
Video Inspection
Every San Bruno job starts with a camera pass. We push an inspection camera into the first run before we touch any tool, and we show you what we see. In a 1952 Crestmoor home we inspected recently, the return was packed with a dark, oily film that coated the lens on first contact. That photo went to the homeowner, and it dictated the rest of the job. You shouldn’t pay someone to clean ducts blind.

BeforeAfterTrusted Brands We Service in San Bruno
The equipment we use on San Bruno jobs comes from manufacturers you can look up independently: Rotobrush, Nikro, Abatement Technologies, Honeywell, Aprilaire, and Guardsman. These are professional-grade tools built for source removal, not the shop-vac-and-brush setup that gives this industry its reputation. If your system includes an Aprilaire filter housing or a Honeywell whole-house media cabinet, we’re familiar with the components and we clean around them without damaging the seals.
Common Air Duct Cleaning Problems We See in San Bruno Homes
- Jet-exhaust particulate loading. Homes on the north and west sides under SFO departure paths collect a dark, fine-grained residue in ductwork that we rarely see in comparable volume elsewhere on the Peninsula. It fouls filters fast, which is why some San Bruno homeowners replace a one-inch filter twice as often as their friends in Burlingame.
- Marine-fog moisture and microbial growth. San Bruno sits between the coastal hills and the Bay, and the persistent marine layer keeps attic and crawlspace humidity elevated much of the year. Inside flex ducts that never fully dry out, mold and mildew colonize quickly. A standard dry-brush cleaning misses this; a HEPA-filtered negative-pressure extraction does not.
- Deteriorating flex-duct connections. Original tract homes from the 1950s often have flex sections that were added during a remodel or a partial replacement. Those connections loosen over time. A cleaning crew that doesn’t check duct age before agitating can tear a connector and blow debris toward the air handler. We camera-check first, every time.
- Fogging sanitizer upsells that mask instead of removing. Some companies sell a fogging service as a substitute for actually extracting what’s in the ducts. A fogger can’t remove a three-inch deposit of oily residue; it just adds a chemical scent on top of it. If the source load stays, the smell comes back, usually within a season.
Pricing for Air Duct Cleaning in San Bruno, CA
A typical full-system residential duct cleaning in San Bruno runs $525-$875. Smaller condos or apartments may come in under that range; a large home with multiple return drops or significant contamination can exceed it. Commercial pricing depends on square footage, run count, and access. Here’s a breakdown of what San Bruno homeowners typically pay:
| Service | Typical Range, San Bruno |
|---|---|
| Full System Cleaning (single-family) | $525-$875 |
| Supply or Return Only (one side) | $275-$425 |
| Video Inspection Add-On | $95-$150 |
| Commercial Per-Visit Cleaning | $700-$1,400 |
What drives the price up here compared to drier Peninsula cities is moisture. Ducts that have been humid for years often need longer extraction time and more agitation passes to remove microbial film attached to metal surfaces. We’ll tell you what we found and what it will take, in writing, before we start. We also offer a Free Second Opinion on any written estimate: bring a competitor’s quote and we’ll put our number next to it. Call (806) 606-6902 for your price.

FAQs - Air Duct Cleaning in San Bruno
The black filter you’re seeing is ultrafine particulate from jet exhaust. San Bruno sits directly under SFO departure corridors, and the combustion byproducts that aircraft engines produce settle into the air and get pulled into home HVAC systems. Burlingame is east of the main climb-out path and doesn’t get the same concentration. We’ve photographed the difference in the same week across the two cities; the San Bruno filter is always darker. Call (806) 606-6902 if you want a camera pass to see what’s collecting in the ducts themselves.
Yes. San Bruno’s position between the coastal hills and the Bay means the marine layer sits over the city for long stretches of the year. Attic and crawlspace humidity stays high, and flex ducts that never fully dry become a surface for mold and mildew to colonize. We find microbial film on roughly half of the older systems we inspect in San Bruno, especially in homes without crawlspace vapor barriers. The fix is source removal with HEPA-filtered negative pressure, not a fogger.
A real duct cleaning removes the material that’s actually inside the ducts using negative-pressure extraction and agitation tools. A fogging sanitizer sprays a chemical mist into the same ducts and calls it done. If your ducts carry jet-exhaust residue and moisture-fed microbial growth, a fogger leaves all of that in place; it just adds a smell on top. The material is still there. We document what we remove with before-and-after photos so you know the difference wasn’t just theoretical. Call (806) 606-6902 for a written quote.
You can check the register openings yourself. Pull one off and look inside with a flashlight. Original sheet-metal ducts are rigid, silver, and often show rust at the seams. If you see a plastic-covered wire coil with a shiny or grey inner liner, that’s flex duct, likely from a later remodel. The Crestmoor neighborhood in particular has a patchwork of original metal and newer flex because of the rebuilds after the 2010 pipeline explosion. We camera-inspect every run before quoting so we know what we’re working with before any tool goes in.
Because the return side is where the heaviest contamination collects. The return ducts are under negative pressure, pulling in air from the house, which in San Bruno includes the ultrafine particulate load from SFO departure corridors. If you clean the supply side only, the return side keeps pulling that material through the system, and the blower redistributes it within weeks. A full-system clean addresses both sides and gives you a system that isn’t recontaminating itself the moment it turns on. Call (806) 606-6902 for a written price on the full system.
