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 Broadmoor
Air duct cleaning in Broadmoor runs $450 – $850 for a typical full residential system, and most jobs are finished in a single visit. The price depends on home size, how many returns the system has, and how much biofilm the coastal humidity has left behind. If you’re calling from the Broadmoor Village tract or the streets around Colma Creek, call (980) 447-2498 and we’ll give you a written price before anyone sets foot in your door. No per-vent games, no invoice that changes at the end of the job.
We know Broadmoor’s homes because we work in them every week. The fog that sits over this part of the Peninsula does something specific to forced-air systems, and it’s the reason a real source-removal clean matters more here than it does ten minutes inland.
Why Linden Air Duct Cleaning Is Broadmoor’s Preferred Air Duct Cleaning Company
The Threshold Standard is the reason Broadmoor homeowners call us before other duct cleaners. Every technician we send is background-checked and identity-verified. You get their name and photo before the visit, and they show a photo ID badge at your door. That matters when you’re letting someone into a crawl space under a 1940s Broadmoor home while your kids are upstairs.
We’ve been at this since 2004 as part of the Threshold Group family, and the standing commitments haven’t changed: a written price before work starts, a written guarantee on every repair, and a free second visit if a covered repair fails. Those are not promotional offers. They’re included on every single job. Marcus Veale leads our team, and he holds every tech to the same standard on every Broadmoor job, from the Village to the streets above El Camino Real.
Calls are answered by a live person around the clock. Not a voicemail tree. You can call (980) 447-2498 at 10 p.m. and a human picks up.
Air Duct Cleaning Services in Broadmoor
Air Duct Cleaning Services in Broadmoor mean one thing on paper: we remove the accumulated dust, debris, and biological growth from the full duct run, then verify it with camera footage. In practice, in this CDP, the job is as much about moisture management as it is about dust. A proper clean here should include the crawl space and attic runs, because those are the surfaces where fog-belt condensation condenses and feeds mold all year. Expect $450 – $850 depending on the size of the system, and expect to see before-and-after photos of your own ducts.
Residential Duct Cleaning
For the single-family homes that define Broadmoor, typically two-to-four bedroom 1940s and 1950s construction, residential cleaning usually covers 8 – 14 supply runs, one or two returns, and the trunk lines. We run the system under negative pressure with HEPA filtration and agitate the inner walls to release what’s stuck. We’re not fogging anything. We’re pulling material out.
Full System Cleaning
Full system cleaning adds the return side, the plenums, and the blower compartment. In Broadmoor’s damp crawl spaces, returns are often the most contaminated part of the system, because that’s where cold metal sweats and where flex connections degrade. If your system has never been cleaned, this is the service we recommend.

HVAC Duct Cleaning in Broadmoor
HVAC Duct Cleaning in Broadmoor is the same physical job, but the focus is the interaction between the ducts and the furnace or air handler. Over decades of fog-season cycling, condensation wets the inside of trunk lines every time the furnace kicks on and off. Dust sticks to that moisture, layer by layer, until the ducts are lined with a gray paste. In Broadmoor, the HVAC side of the clean is the side that determines whether the musty smell comes back in four weeks or not.
Supply Duct Cleaning
Supply ducts carry the air you actually breathe, so this is where a proper clean pays off fastest. We see surface mold at register boots in Broadmoor even in homes with no plumbing leaks, no roof damage, and no standing water anywhere. It’s pure fog-belt humidity. Removing that growth from the supply side, not masking it with a scent, is the job.
Return Duct Cleaning
Return ducts pull air from your living space back to the furnace. In Broadmoor’s original 1950s sheet-metal systems, failing flex connections at the return drops let moist crawl space air straight into the duct run. We identify those during the camera inspection and flag them for repair. Cleaning the returns without addressing the breach is temporary at best.
Trusted Brands We Service in Broadmoor
Our Broadmoor techs run professional-grade equipment from Rotobrush and Nikro. That matters here because the biofilm we need to remove in fog-belt ductwork does not come out with a shop vac. We also install air-quality products from Honeywell and Abatement Technologies, including filtration upgrades that make sense for high-humidity return air. We stock common parts in our metro fleet, which means most Broadmoor jobs are completed the same day they’re scheduled.
Common Air Duct Cleaning Problems We See in Broadmoor Homes
- Visible surface mold at register boots. This is the signature Broadmoor finding. No leak, no flood, just chronic marine-layer humidity condensing on cold metal. A proper source-removal clean removes it; fogging a sanitiser over it feeds it.
- Original 1940s and 1950s sheet-metal trunks with failing flex connections. These post-WWII homes were built fast, and the ductwork shows it. Degraded flex collars are the single biggest air-quality breach we find in the Village tract.
- Condensation-wet inner walls in crawl space runs. Every furnace cycle that pulls damp air across cold duct surfaces deposits a new layer of moisture. Dust binds to it. Then biological growth starts.
- A musty smell that returns weeks after a cheap cleaning. That happens when someone fogged or sprayed without removing the underlying accumulation. The moisture stays, and the growth comes right back.
Pricing for Air Duct Cleaning in Broadmoor, CA
A straightforward single-system home in Broadmoor typically runs $450 – $650. Larger two-story layouts or homes with multiple returns run $650 – $850.

FAQs About Air Duct Cleaning in Broadmoor
The smell is almost always biological growth inside the ducts, fed by fog-belt humidity rather than a plumbing or roof leak. Cold duct surfaces in your crawl space attract condensation every time the furnace cycles, and that moisture, combined with decades of accumulated dust, supports mold and mildew near the register boots. The fix is removing the material from inside the ducts, not masking it. Call (980) 447-2498 and we’ll confirm it with a camera inspection.
Yes, measurably. Broadmoor sits in the Peninsula’s coastal fog belt where the marine layer lingers nearly year-round, so relative humidity stays elevated even in summer. San Mateo and San Bruno burn off the fog more regularly, which gives duct surfaces a chance to dry. In Broadmoor, the damp cycle is nearly continuous, so biofilms form faster and return faster after a shallow clean.
A real clean includes negative-pressure extraction with HEPA filtration, mechanical agitation of the supply and return runs, and camera-verified before-and-after footage. A fogging sanitiser that is sprayed without source removal is an upsell that can make the problem worse: the wet, sticky layer it leaves behind feeds new microbial growth in already-humid ducts. Don’t pay for a UV light or fogger while the flex connections are still failing. Call (980) 447-2498 for an honest quote.
It changes what we look for. Original sheet-metal trunks from the post-WWII tract era usually have degraded flex connections and unsealed joints that pull damp crawl space air straight into the duct run. We inspect those before and during the clean, and if we find failing collars, we recommend repair before or alongside the cleaning so the job actually holds.
Every three to five years for most Broadmoor homes, and closer to every three if you have a damp crawl space, original 1950s ductwork, or you notice a musty smell at the start of heating season. The marine layer does not let up, so the condensation cycle does not let up. A home that might go seven years in Sacramento needs more attention here. Call (980) 447-2498 and we’ll help you set a schedule that matches your system.
