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.

AfterHow Much Does Air Duct Cleaning Cost in San Francisco?
Air Duct Cleaning services in San Francisco typically cost $450 to $900 for an average single-family home, with most jobs landing between $550 and $700. Larger Victorian and Edwardian houses with multiple systems or long duct runs push past $1,200, while a small condo with one HVAC system often comes in under $500. The number that matters is the one in writing before any technician touches your vents, and at Linden Air Duct Cleaning that written price comes first, every time.
We’re an independently owned and operated location within the Threshold Group family, serving Bay Area homeowners since 2004 under the Threshold Verified standard. If you want a straight answer on what your San Francisco home will cost, call (980) 447-2498 and a live person will pick up, day or night.
Air Duct Cleaning Cost Breakdown (2026)
Here’s how air duct cleaning costs in nearby San Jose, CA compare, and how pricing breaks down in the San Francisco market this year. These are real ranges, not teaser rates that change once the truck arrives.
| Service | Typical Price Range | Notes |
|---|---|---|
| Standard duct cleaning, 1 system | $450 – $700 | Up to 10 vents, includes supply and return lines |
| Whole-home, 2+ systems | $750 – $1,200 | Common in two-story Noe Valley and Richmond District homes |
| Condo / small unit (under 800 sq ft) | $350 – $500 | Single system, limited run length |
| Dryer vent cleaning (add-on) | $150 – $250 | Roof or long-run vents cost more |
| Air duct repair (sealing, reconnecting) | $250 – $850 | Depends on how many runs need work |
| Mold or heavy contamination treatment | $400 – $1,500 additional | Usually tied to a past moisture event |
| Sanitizing / antimicrobial fogging | $150 – $400 | Optional, priced separately |
| Filter upgrade (Honeywell, Aprilaire) | $80 – $350 | Depends on filter and housing |
What pushes a job toward the top of these ranges? Number of systems, duct length, how accessible the runs are, and how much contamination we find. A Sunset District home with two furnaces and 40 feet of attic flex duct is a different job than a Marina condo with short hard-pipe runs. We don’t estimate by square footage alone, and we don’t guess over the phone. A quick look at your setup gives you a real number you can hold us to.
A note on the low end: when you see a $99 or $149 air duct cleaning advertised in San Francisco, that price almost always covers one vent or a single trunk line, not the full system. The final invoice is where the rest shows up. We put our price in writing before any work begins, so there’s no surprise line at the end.
What Affects Air Duct Cleaning Pricing in San Francisco
Pricing here isn’t the same as air duct cleaning costs in Seattle, WA or the East Bay. A few local realities shape the number.
- Housing stock and duct age. A large share of San Francisco homes were built before 1940. Victorian and Edwardian houses often have original or retrofitted ductwork with odd turns, undersized runs, and asbestos-era materials we have to work around. Older systems take longer, and time is the biggest cost driver.
- Number of HVAC systems. Two-story homes in areas like Noe Valley, the Inner Richmond, and Bernal Heights frequently run two separate systems. Each one is cleaned as its own job.
- Attic and crawlspace access. Fog Belt homes near the coast deal with year-round damp air, and that moisture feeds dust, mildew, and debris inside ducts and attics. If access means crawling through a tight knee wall, the labor adds up.
- Contamination level. Pets, recent remodeling, or a past water leak all raise the workload. Drywall dust from a kitchen remodel can coat an entire system in a weekend.
- Duct material. Hard metal pipe cleans fast. Flex duct, common in additions and remodels, has ridges that trap debris and takes more care.
- Add-ons you choose. Dryer vent cleaning, sanitizing, and filter upgrades are separate line items. We’ll tell you plainly which ones your home actually needs.
If you want to understand how we handle older Bay Area ductwork specifically, our home page walks through the equipment and methods we bring to every job, including the Rotobrush and Nikro machines we use for negative-pressure extraction (that’s the vacuum-and-seal approach that pulls debris out instead of blowing it around your house).
How to Save on Air Duct Cleaning
There’s no coupon you need to chase. A few sensible moves keep the price honest.
- Get the price in writing before work starts. This is the single biggest money-saver. An upfront written price means nothing changes mid-job. It’s a standing commitment at Linden Air Duct Cleaning, not a promotion.
- Bundle duct and dryer vent cleaning. Doing both in one visit usually costs less than two separate trips, and dryer vents are a real fire risk we’d rather you address anyway.
- Clear your vents first. Move furniture and take down any floor grates before we arrive. It sounds small, but it shortens the visit.
- Skip add-ons you don’t need. Sanitizing and antimicrobial fogging help in some homes and do nothing in others. Ask us, and we’ll tell you honestly whether yours is one of them.
- Address repairs before they spread. A disconnected duct run is cheap to fix early. Left alone, it dumps conditioned air into your attic for years and drives up both your energy bill and the eventual repair cost.
Everything starts with a free estimate. Call (980) 447-2498 and a real person will answer, any hour of the day or night. No voicemail loop, no callback queue.
FAQs – Air Duct Cleaning Cost
How much does air duct cleaning cost in San Francisco?
Most San Francisco homeowners pay between $450 and $900, with the average landing near $600. Condos usually fall under $500; multi-system Victorian and Edwardian homes run $750 to $1,200 or more. Call (980) 447-2498 for an exact quote on your address. Estimates are free.
Is it cheaper to clean my ducts or replace them?
Cleaning is almost always cheaper. Full duct replacement in San Francisco can run $3,000 to $8,000, so cleaning at $450 to $900 makes sense for the vast majority of homes. Replacement is only worth considering when ductwork is collapsed, badly sized, or contaminated beyond cleaning. We’ll tell you which one you’re facing.
Can you come today?
Often, yes. Same-day appointments are frequently available depending on the schedule. When you call, you’ll reach a live person 24/7 who can check availability right away. Call (980) 447-2498 to see what’s open.
Why is air duct cleaning more expensive in San Francisco than other cities?
Labor costs, older housing stock, and tight attic or crawlspace access all add to the job here compared to air duct cleaning costs in Staten Island, NY. A pre-1940 home with original ducts takes more time and care than a newer suburban build. That’s the honest reason the San Francisco number runs higher.
Do you offer a written guarantee?
Yes. Every air duct repair from Linden Air Duct Cleaning carries a written guarantee, and it’s backed by our 365-Day Done Right Promise: if the work isn’t right, we make it right, and we come back at no charge if a covered repair fails. It’s in writing on the job, not just in a phone conversation.
One more thing worth knowing before you book anyone: when our technician is headed your way, you’ll get their name and photo before they arrive, and they’ll show a photo ID badge at the door. Every technician is background-checked, identity-verified, and in a clean, marked uniform. If you’re home alone, have young kids, or simply don’t like opening the door to a stranger, that protocol exists for exactly that reason. It’s called The Threshold Standard, and we’ve held it since 2004.
Pricing reflects the San Francisco market as of 2026. Linden Air Duct Cleaning offers free estimates – call (980) 447-2498.
