Fast, Reliable Air Duct Cleaning Across San Francisco
Air duct cleaning in San Francisco typically costs $450 – $850 for a full residential system, with the final price set in writing before we start. The work takes most of a day, and the real challenge here isn’t the cleaning itself. It’s the housing. San Francisco’s pre-1960 stock has forced-air systems retrofitted into Victorians and Edwardians, which means long, narrow duct runs, galvanized steel with asbestos tape, and decades of plaster dust and knob-and-tube wiring fibers packed inside. You need equipment built for that reality, not a portable vacuum and a leaf blower. Call (951) 527-6259 for a free estimate, and we’ll tell you exactly what the job requires before anyone shows up at your door.

We serve every neighborhood in San Francisco, from the fog-heavy Sunset and Richmond out to Bayview, the Mission, Noe Valley, and Pacific Heights. Marcus Veale leads our crew, and he makes sure every tech who arrives at a San Francisco home is background-checked, photo-badged, and introduced by name before the visit. That’s the Threshold Standard, and we’ve run that way since 2004 as part of the Threshold Group family.
Why Linden Air Duct San Francisco Is San Francisco’s Preferred Air Duct Cleaning Company
San Francisco homeowners call us for a specific reason: we treat old ductwork with the caution it demands. Most of the homes here were built before 1960, and the duct runs reflect that. They wind through tight framing, they’re held together with asbestos tape, and they’ve been collecting ocean salt and fog moisture for decades. A careless cleaning job can make things worse, and that’s the honest truth. We use negative-pressure extraction from Rotobrush and Nikro equipment, which means debris gets pulled out of the duct rather than pushed into your living room.
Our Air Duct Cleaning team has spent years working inside San Francisco’s specific housing types, and it shows in how we approach a job. We camera-inspect before we agitate, we verify airflow after, and we don’t sell fogging treatments as a substitute for source removal. San Francisco customers also get something no price-based competitor offers: a written price before any work starts, every time, no exceptions. The number we quote is the number you pay. And if a repair doesn’t hold, we come back at no charge. That’s our 365-Day Done Right Promise, and it’s written into every job.
When you call us, a live person answers. Not a voicemail loop. That matters when you’re home alone, or you’ve got kids, or you’re trying to decide whether the company on the other end of the phone is someone you can actually let through the door. Our reputation with San Francisco customers comes down to that accountability, and it’s why homeowners here choose us over the coupon mailers.
Styles & brands we work with




Commercial Air Duct Cleaning in San Francisco
Commercial Air Duct Cleaning in San Francisco means working in buildings where access is even tighter than a typical Victorian home. We handle small apartment buildings, fourplexes, offices, restaurants, and retail spaces across the city. The job involves source-removing debris from supply and return duct runs, inspecting for the corrosion and microbial growth that San Francisco’s salt air accelerates, and documenting the work with before-and-after camera footage. A commercial clean in San Francisco runs $800 – $2,500 depending on the number of units or zones, system layout, and how much of the ductwork is reachable without cutting access panels. We give you a written price first, not a range that balloons later.
Apartment and Fourplex Duct Cleaning
Older San Francisco apartment buildings share one thing: duct runs that snake through walls no one has opened since the Eisenhower administration. We clean them with negative-pressure equipment and HEPA filtration, which is the only safe way to handle decades of accumulated plaster dust and wiring insulation debris. Landlords in the Inner Richmond and Sunset call us after tenant complaints about musty air, and the fix usually starts with source removal, not a fogging spray.
Office and Retail Duct Cleaning
Commercial spaces near downtown and SoMa deal with their own issue: recirculated air for 9-plus hours a day, which concentrates whatever is in the ducts. We schedule after-hours or weekend work when buildings are empty, and every job ends with video verification. You see what we saw before, and what you got after.
Air Duct Cleaning Services in San Francisco
Air Duct Cleaning Services in San Francisco cover the full path air travels through your home: supply ducts, return ducts, the plenum, and the main trunk lines. We clean all of it, not just the vents you can see from the floor. A typical single-family home in San Francisco costs $450 – $850, and we confirm the exact number in writing before work begins. What changes the price is access: if your furnace is squeezed into a basement crawlspace in the Richmond or a closet in a Noe Valley flat, the labor is different than a wide-open garage install.
Supply and Return Duct Cleaning
Supply ducts push conditioned air out. Return ducts pull room air back in. Both need cleaning, because the return side often carries the most debris: skin cells, pet hair, cooking residue, and the fine gray salt-and-dust film that San Francisco’s ocean air deposits on everything. We clean both sides under negative pressure and camera-inspect after.

Full System Cleaning With Video Inspection
This is the package that makes sense for most San Francisco homeowners. We clean supply and return runs, the main trunk, and the plenum, then run a camera through every accessible duct run and show you the footage. If we find corrosion spots or damage, we flag them and tell you what needs attention now versus what can wait. No scare tactics. Just honest reporting.

Trusted Brands We Service in San Francisco
We run Rotobrush and Nikro cleaning equipment, and we work with air-quality products from Abatement Technologies, Guardsman, and Honeywell. That matters in San Francisco because the equipment has to handle long, narrow, corrosion-prone runs without falling short. We keep the consumables and filter media on hand for San Francisco jobs, which means we’re not waiting on a shipment to finish your clean. When you’ve got a 1920s Edwardian in the Inner Richmond that needs source removal, the last thing you want is a crew showing up with tools meant for a suburban tract home.

AfterCommon Air Duct Cleaning Problems We See in San Francisco Homes
- Corrosion from ocean salt and fog. In the Sunset and Richmond districts especially, the daily marine layer leaves a fine gray film on metal ductwork. Over years it eats through galvanized steel, and we regularly find rust-through spots within five blocks of Ocean Beach.
- Decades of plaster dust and wiring debris. Homes built before 1960 in the Mission, Bernal Heights, and Glen Park carry the residue of original knob-and-tube wiring and old plaster walls. It settles in the ducts and narrows airflow dramatically.
- Asbestos tape on duct seams. Many pre-1960 San Francisco systems used asbestos tape to seal joints. Aggressive brushing can disturb it, so we use negative pressure and careful source removal instead of brute-force agitation.
- Microbial growth in fog-belt neighborhoods. Closed windows, damp air, and organic dust build a film inside ducts that regrows quickly if you don’t remove the source. Fogging sprays mask the smell for a week or two. They don’t fix it.

FAQs About Air Duct Cleaning in San Francisco
Your ducts pull return air from inside the house, not directly from outside, but the moisture and salt in San Francisco’s marine air enters through windows, crawl spaces, and wall penetrations. Once that damp, salty air settles in the ducts, it combines with organic dust to form a thin film on the metal. That film is what feeds microbial growth, and it’s why homes within a few blocks of Ocean Beach show corrosion sooner than places in Noe Valley or the Mission. A proper clean source-removes that film under negative pressure. Call (951) 527-6259 and we’ll inspect your system and tell you honestly whether it’s needed.
No. Fogging sprays coat the inside of ducts with a chemical that masks odor for a week or two, but they don’t remove the salt crust, the organic film, or the debris that microbial growth feeds on. In the Richmond and Sunset, the regrowth window is short because the moisture source never goes away. Source removal with negative pressure, followed by HEPA filtration, is the only approach that addresses the actual cause. If a company leads with a fogging upsell, ask them what they’re removing first. Then call (951) 527-6259 for a straight answer.
San Francisco’s pre-1960 housing stock has long, narrow, winding duct runs retrofit into Victorian and Edwardian floor plans. Portable vacuums can’t hold negative pressure across those runs, which means dislodged debris stays inside and blows into living spaces. True negative-pressure machines, like the Rotobrush and Nikro units we use, pull the debris out at the source. That’s the difference, and it’s why the equipment conversation matters more in San Francisco than in suburbs with wide, straight, modern duct runs.
Yes, if it’s done wrong. Asbestos tape on pre-1960 duct seams can release fibers if it’s aggressively brushed or disturbed without proper containment. We treat any system with suspect tape as a hazardous-material job: negative pressure, HEPA filtration, careful source removal, and no brute-force agitation. The wrong cleaning method can absolutely make your air worse, which is why you want a crew that knows what it’s looking at before it starts. Call (951) 527-6259 and we’ll tell you what your system needs.
If your vents push out visible dust, your rooms smell musty within hours of cleaning, or you can see dark residue around the register covers, the ducts themselves are carrying debris. A filter change is a stopgap. A camera inspection tells you for certain, and we include that with every full system cleaning. For an honest assessment without a hard sell, call (951) 527-6259 and we’ll walk you through what we’d look for and what it costs.
